Book Review: The Precipice

I have titled my annual blog post summarizing where I donate my charitable budget as “How can we use our resources to help others the most?” This is the fundamental question of the Effective Altruism movement which The Precipice‘s author, Toby Ord, helped found. For a while, Toby Ord focused on figuring out how to fight global poverty, doing the most good for the worst off people in the world. Now, he is focusing on the long term future and existential risk.

The Precipice is fantastic. It’s incredibly well written, engaging, and approachable. It covers a lot of ground from why we should care about the world, what risks humanity faces in the future, how we might think about tackling those risks, and what the future might look like if we succeed.

The Precipice eloquently interweaves fairly philosophical arguments with more empirical analysis about the sources of existential risk and tries to statistically bound them. The book discusses a pretty concerning topic of the potential end of humanity, but it does so with an eminently reasonable approach. The complexities of philosophy, science, probability, epidemiology, and more all are brought into the narrative, but made easily digestible for any reader. I honestly wish Toby Ord could teach me about everything, his writing was so clear and engaging.

The main discussion is never overwhelming with technical details, but if you ever find a point interesting, even the footnotes are amazing. At one point I came up with a counterpoint to Ord’s position, wrote that down in my notes, only to find that the next several paragraphs addressed it in its entirety, and there was actually a full appendix going into more detail. Honestly, this will be less of a book review and more of a summary with a couple final thoughts, because I think this book is not only excellent, but its content is perhaps the most important thing you can read right now. You are welcome to read the rest of this blog post, but if you have found this compelling so far, feel free to stop reading and order Toby Ord’s book posthaste.

Existential Risk

The consequences of 90% of humans on Earth dying would be pretty terrible, and given our relatively poor response to recent events, perhaps we should better explore other potential catastrophes and how we can avoid them. But The Precipice goes further. Instead of 90% of humans dying, what happens if 100% of us die out? Certainly that’s strictly worse with 100>90, but in fact these outcomes are far apart in magnitude: if all humans die out today, then all future humans never get to exist.

There’s no reason we know of that would stop our descendants from continuing to live for billions of years, eventually colonizing the stars, and allowing for the existence of trillions of beings. Whatever it is that you enjoy about humanity, whether that’s art, engineering, or the search for truth, that can’t continue if there aren’t any humans. Full stop. As far as we know, we’re the only intelligence in the universe. If we screw up and end humanity before we get off this planet, then we don’t just end it for ourselves but perhaps we end all intelligent life for the remaining trillions of years of the universe.

Even though I was aware of the broad thesis of the book, I was continually impressed with just how many different angles Ord explores. He early on notes that while we might normally think of a catastrophic extinction event, like an asteroid impact, as the thing we are keen on avoiding, in fact there are several scenarios that would be similarly devastating. For example, if humanity were to suffer some calamity that did not kill everyone but left civilization stuck at pre-industrial technology, that would also preclude humanity from living for trillions of years and colonizing the stars. A 1984 style global totalitarian state would also halt humanity’s progress, perhaps permanently.

Ord also discusses the fundamental moral philosophy implications of his thesis. The natural pitch relies on utilitarian arguments as stated above; if humanity fails to reach its potential, this not only harms any humans currently alive but all future generations. Other arguments against extinction include a duty to our past and what we owe to our ancestors, the rights of those future generations who don’t get to decide for themselves, and the simple fact that we would lose everything we currently value.

The book categorizes three types of risk: natural, anthropogenic, and future risks. Natural includes asteroids, supervolcanoes, and stellar explosions. These are pretty diverse topics, and Ord is quite informative. The story about asteroid risk was particularly fascinating to me. In the 90s, the relatively new discovery of the dinosaurs’ demise led Congress to task NASA with identifying all the largest near-Earth asteroids to see if they pose a threat to Earth. They allocated some money, and NASA tracked every near-Earth asteroid over 10 km in length, and determined that none pose a threat in the next century. They then moved on to 1 km asteroids and have now mapped the vast majority of those as well. The total cost of the program was also quite small for the information provided — only $70 million.

This is one of the rare successes in existential risk so far. Unfortunately, as Ord points out several times in the book, current foundational existential risk research at present is no more than $50 million a year. Given the stakes, this is deeply troubling. As context, Ord points out that the global ice cream market is about $60 billion, some 1000x larger.

I’ll skip the other natural risks here, but the book bounds natural risk quite skillfully; humans have been around for about 200,000 years, so it seems natural risk can’t be much higher than 0.05% per century. Even then, we’d expect our technologically advanced civilization to be more robust to these risks than we have been in the past. Many species survived even the largest mass extinctions, and none of them had integrated circuits, written language, or the scientific method.

That doesn’t mean that all risk has declined over time. On the contrary, according to Ord, the vast majority of existential risk is anthropogenic in origin. Nuclear weapons and climate change dominate this next section. It’s remarkable just how callous early tests of nuclear weapons really were. Ord recounts how there were two major calculations undertaken by a committee of Berkeley physicists before the Manhattan project got underway in earnest. One was whether the temperature of a sustained nuclear reaction would ignite the entire atmosphere in a conflagration (the committee believed it would not). The other was whether Lithium-7 would contribute to a thermonuclear explosion (it was believed it would not). It turns out that Lithium-7 can contribute to a thermonuclear explosion as was found out when the Castle Bravo test was about three times larger than expected, irradiating some 15 nearby islands.

It turned out the other calculation was correct, and the first nuclear explosion in 1945 did not ignite the atmosphere. But clearly, given the failure of the other calculation, the level of confidence here was not high enough to warrant the risk of ending all life on Earth.

Luckily, current risk from nuclear weapons and climate change that would wipe out humanity seems quite low (although not zero). Even a nuclear winter scenario or high sea level rise would not make the entire Earth uninhabitable, and it is likely humans could adapt, although the loss of life would still be quite catastrophic.

Instead, the bulk of the risk identified by Toby Ord is in future technologies which grow more capable every year. These include engineered pandemics from our increasingly powerful and cheap control over DNA synthesis, as well as artificial intelligence from our increasingly powerful and integrated computer systems.

The threat of engineered pandemics is particularly prescient as I write this in August 2020 where SARS-CoV-2 is still sweeping the world. Ord notes that even given quite positive assumptions about whether anyone would want to destroy the world with a virus, if the cost is cheap enough, it only takes one crazy death cult to pull the trigger. Even an accidental creation of a superweapon is a serious risk, as production is cheap and there are many examples of accidental leakages of bioweapons from government laboratories in the past. Unfortunately, we are also woefully unprepared on this front. The Biological Weapons Convention had a budget of $1.4 million in 2019, which Ord notes is less than most McDonald’s franchises.

Risks from unaligned artificial intelligence are similarly related to technical advancements. Ord notes that artificial intelligence has had some impressive achievements recently from photo and face identification to translation and language processing to games like Go and Starcraft. As computer hardware gets better and more specific, and as we discover more efficient algorithmic applications of artificial intelligence, we should expect this trend to continue. It therefore seems plausible that sometime in the future, perhaps this century, we will see artificial intelligence exceed human ability in a wide variety of tasks and ability. The Precipice notes that, were this to happen with some sort of general intelligence, humanity would no longer be the most intelligent species on the planet. Unless we have some foresight and strategies in place, having a superior intelligence with it own goals could be considerably dangerous.

Unfortunately, we are already quite poor at getting complex algorithms to achieve complicated goals without causing harm (just take a look at the controversy around social media and misinformation, or social media and copyright algorithms). The use of deep learning neural networks in more high stakes environments means we could be facing opaque algorithmic outcomes from artificial intelligence that we don’t know if we’ve correctly programmed to achieve the goals we actually want. Throw in the fact that human civilizational goals are multifaceted and highly debated, and there is a great deal of mistakes that could occur between what humans “want” and what a superior intelligence attempts to accomplish. While Toby Ord doesn’t think we should shut down AI research, he does suggest we take this source of risk more seriously by devoting resources to addressing it and working on the problem.

So What Do We Do?

I’ve spent a lot of time on enumerating risks because I think they are a concrete way to get someone who is unfamiliar with existential risk to think about these ideas. But Ord isn’t writing a book of alarmism just to freak out his audience. Instead, starting with the high levels of risk and adding the extremely negative consequences, Ord details how we might begin to tackle these problems. Unprecedented risks come with modeling challenges: if an existential risk cannot by definition, have ever occurred, how can we know how likely it is? We have to acknowledge this limitation, use what incomplete knowledge we can have access to (number of near misses is a good start), and start building institutions to focus on solving these hard problems.

International coordination is a major factor here. Many of these problems are collective action problems. Humanity has found ways around collective action issues with international institutions before (nuclear arms treaties), and so we need to replicate those successes. Of course, we can’t establish new or better institutions unless we get broad agreement that these issues are major problems that need to be solved. Obviously, that’s why Ord wrote this book, but it’s also why I feel compelled to blog about it as well. More on that momentarily.

In this section of the book, The Precipice outlines preliminary directions we can work towards to improve our chances of avoiding existential catastrophes. These include obvious things like increasing the funding for the Biological Weapons Convention, but also discussions on how to think about technological progress, since much of our future existential risk rises as technology improves. We also obviously need more research on existential risk generally.

Finally, I want to wrap up discussing Appendix F, which is all of Ord’s general policy recommendations put into one place. As policy prioritization has long been an interest of mine, I found Toby Ord’s answer to be quite fascinating. I wrote a post a few months back discussing the highest impact policies actually being discussed in American politics in this election cycle. Comparing it to Toby Ord’s recommendations, the overlap is essentially nonexistent except for some points on climate change, which most democrats support such as the U.S. rejoining the Paris Climate Agreement. There’s also a point about leveraging the WHO to better respond to pandemics, and given Trump has essentially done the exact opposite by removing U.S. funding for the WHO, I suppose I should at least include that as relevant policy debate.

I want to emphasize that Ord has 9 pages of policy ideas, and many of them are likely uncontroversial (improve our understanding of long period comets, have the Biological Weapons Convention have a real budget), but our political system is failing to even address these challenges, and I think it’s important to highlight that.

There is room for optimism; human knowledge is improved by discussion and research, and that includes reading and blogging. If you find these ideas interesting, or even more broadly, if you think there are valuable things in the world, one of the most effective activities you could do this year might be to just read The Precipice. Even without the weight of humanity, the concepts, problem solving, and prose are worth the read all by themselves. This is definitely by favorite book I’ve read this year, and I’ve skipped over summarizing whole sections in the interests of time. Ord even has a whole uplifting chapter about humanity’s future potential, and is overall quite positive. Please attribute any gloominess on this topic to me and not the book.

And if you do read this book, it also just makes for intriguing conversation. I couldn’t help but tell people about some of the ideas here (“are supervolcanoes a national security threat?” ), and the approach is just wonderfully different, novel, and cross-disciplinary.

For more on this, but slightly short of reading the whole book, I also recommend Toby Ord’s excellent interview on the 80000 Hours Podcast. On that page you can also find a host of awesome links to related research and ideas about existential risk. I’ll also link Slate Star Codex’s longer review of The Precipice, and places to buy it.

Links 2019-03-07

First links post in a while because I have some housekeeping. After trying to have comments just on reddit, I’ve realized it makes way more sense to just have comments right below the articles again. I really don’t like the WordPress default comment system so I’ve opted instead for Disqus. These have been implemented for a while, but I wanted to bring your attention to them.

I’ve also finally updated the site to default to https. Kind of an embarrassment for a site promoting encryption to not have https defaulted, but this blog is a volunteer project done for personal interest (and personal expense!).

I’ve removed Greg Mankiw’s blog from the sidebar because I realized I wasn’t reading it much anymore and it doesn’t talk about too much interesting econ stuff very often. I also removed Jeffrey Tucker’s blog beautiful anarchy, because I don’t think he posts there anymore now that he’s running aier.org.

I’ve added gwern.net because this past year I’ve realized how much more I’ve been going to his site even though I’ve known about it for a long time. Gwern is a rationalist independent researcher. He doesn’t really write blogs so much as essays on a topic. I recommend his site wholeheartedly. Seriously, his site is the first link on this post for a reason. If you are overwhelmed by the amount of content, see if anything in his “Most Popular” or “Notable” categories jump out at you and start there. I personally found “Embryo Selection For Intelligence” to be quite engrossing.

Slate Star Codex has had some good posts about the importance of OpenAI’s GPT-2. First some background on GPT-2. Next, GPT-2 seems to have learned things haphazardly, in almost a human-like way, to attain its goals of creating good responses to prompts. It connects things in a stream of consciousness reminiscent of a child’s thoughts. As Scott says, simply pattern matching at a high level is literally what humans do.

Also on AI, I found an amazing 2018 AI Alignment Literature Review and Charity Comparison by LessWrong user Larks. It’s a very impressive in depth look at groups concerned about the AI alignment problem.

From Vox: “The case that AI threatens humanity, explained in 500 words”.

Noah Smith writes A Proposal for an Alternative Green New Deal. It makes vastly more sense than the vague, progressive wishlist discussed by current Democratic members of Congress. However, even Smith’s suggestions seem pretty poorly thought out to me; he endorses massive subsidies to green technology, on the order of $30 billion a year, without addressing how the state will know where to invest the money. As I recall, the government isn’t a great central planner. He also just kind of tosses in there universal health insurance, apparently paid for by the government, which sounds like Medicare for all. That seems to both massively politically complicate anything actually trying to fix climate change, and also destroy the entire federal budget, which I think is a national security problem.

Related, on a more nuanced note, John Cochrane discusses a letter signed by many economists endorsing a carbon tax, which seems much more precise and useful to people concerned about climate change. To make it politically palatable, they suggest making a carbon dividend paid to all taxpayers out of this tax. Noah Smith also endorsed this approach as just one piece of his Green New Deal. On brand, The Economist endorses carbon taxes as well.

Bitcoin Hivemind developer Paul Sztorc writes about Bitcoin’s future security budget. It’s a really good technical discussion of how Bitcoin can be funded in the future, and why we need sidechains to help pay for the cost of keeping Bitcoin secure.

Bruce Schneier writes about the need for Public Interest Cybersecurity, envisioning it as a parallel to public interest legal work. It’s an interesting take, and I’m not sure how I feel about it. On the one hand, he’s right that lawmakers know little about the technologies they are supposed to regulated, but that’s also true of literally every industry. Sure it would be great if we had more things like the EFF, but I’m have to ask 80,000 Hours if they thought people going into charity work should work for the EFF or AI Alignment research or other existential risk. I’m also not sure I agree that there aren’t enough incentives to invent new security protocols. Google is taking security very seriously on their own, but so are tons of Bitcoin and cryptocurrency developers who are constantly seeking ways to make their projects more secure and do more creative things with crypto.

The U.S. trade deficit hit a 10 year high. Here is the actual Bloomberg article. This is silly political bickering, so I won’t spend much time on it, but it reflects just how the president fails to grasp very simple economics. The trade deficit doesn’t mean anything by itself, it’s just a measure of the goods traded, and it’s not even very good at that (goods designed here but manufactured in another country see their whole value “subtracted” in the trade deficit despite American labor inputs). The drivers of the trade deficit are things like relative values of currencies and national savings rates, not the levels of tariffs. Meanwhile, Trump’s tax cuts have spurred U.S. growth while the rest of the world has been sluggish, leading to higher trade deficits because Americans are relatively more wealthy. This flurry of economic activity prompted the Fed to raise rates to stave off inflation, which also drives up the trade deficit, and so Trump has taken the horrible tact of trying to publicly attack the Fed to lower rates, which is terrible for any sort of responsible Fed policy. The whole thing is a ridiculous mess which could have been avoided if Trump had any semblance of economic knowledge.

The Fifth Column podcast is a highly entertaining libertarian politics podcast. Episode 132 is a little different as Michael Moynihan takes the opportunity to interview Mark Weisbrot, Co-Director of the Center for Economic and Policy Research, a left-wing think tank, on the Maduro government in Venezuela. I have a lot of thoughts on this interview, but my foremost is whether Weisbrot counts as an actual representative voice of the Left. I think one of the worst things social media does is to hold up the most controversial person on one side because they generate the most clicks and buzz and force both sides to jump in and flame each other. In an hour long interview, Weisbrot takes, as far as I can tell, no opportunity to criticize the Maduro regime, nor offers any way in which they could have improved their policies. He accepts and touts statistics that support his view, and dismisses, minimizes, or ignores stats that counter him–even if they are all from the same source! Even though he’s a big deal at a left-wing think tank, I have to point out that most left-leaning academics don’t need to be in think tanks because most university politics skew left. This might explain how someone with this level of willful ignoranceg could hold such a key position. I think the interview is worth listening to if you would like to see the extent of what humans can do to put up mental barriers to seeing their own logical inconsistencies and motivated reasoning. Nonetheless, I feel bad about linking to this interview as I think it unfairly represents actual socialists who would like to nationalize all industries and seize the means of production.

Urbanization and Free Markets

I’m not an environmentalist. I find global warming problematic because it will likely make living on Earth more expensive for humans. Preservation of natural resources is not inherently important to me because I don’t find it morally wrong to consume these resources at high levels. Nonetheless, it could be valuable to preserve natural resources if there is a tragedy of the commons where resources are underpriced by the market and are thus being inefficiently overconsumed. I also think humans tend to enjoy at least visiting and observing pleasant natural land and seascapes, but it only makes sense to preserve them to the extent of which the value of observing these natural areas outweighs their economic value in improving human lives through development.

Unfortunately, I find a lot of the arguments for urbanization tend to emphasize the environmental benefits. These types of arguments will not do well in convincing libertarians that they should also promote urbanization. The goal of this post is to present an argument for libertarians, classical liberals, and free market economists on why they should be interested in urbanization and urban policy.

Cities

Cities are a vital part of human civilization due to specialization, economies of scale, and network effects. You can’t build a hospital with specialized departments and research facilities in a town of 100 people. You can’t make an engineering startup in a town without stores that sell specialized equipment. You can’t teach specific niche courses in cryptography if your city can’t support a university large enough to have advanced Math and Computer Science departments.

Cities also provide more for their inhabitants to consume due to economies of scale. Cities have more diverse food and cultural entertainment like museums, concerts, or festivals. These experiences are also in constant competition, spurring innovation. We think of cities as being more expensive than living in the country, but that’s somewhat misleading; diverse experiences are available in cities rather than rural areas because they can only be provided cheaply in cities. The selection of products is much narrower in less densely inhabited areas. In cities, supply chains can focus on getting tons of varied products to a single location where everyone lives, rather than transporting fewer standardized products across a giant area. The internet is a mitigating factor to some of this, but it’s also true that you can’t get continued technological innovation without concentrating innovators in cities!

There’s another important point about cities from a libertarian or postlibertarian perspective: they offer anonymity and individuality. Cities pack enough people into an area that you can make choices about your social interactions. Unlike a small town where your personal relationships are limited by geography to the few people in the town. It is far more likely you can meet with others that share your obscure interests in a large city rather than a small town. You’re not forced to conform to what your few neighbors believe are acceptable social behavior or beliefs. Diverse cities allow for varied cultural norms, and I’d argue increased tolerance.

The policies and discussions surrounding urbanization and urban planning have mostly been driven by those on the political left. Their political enemies, the Red Tribe (for more explanation, see section IV of I Can Tolerate Anyone Except the Outgroup), is often identified by its opposition to rich urban elites. Libertarians themselves have streaks of this disdain for progressive cities and yearning for an idealized Jeffersonian yeoman farmer nation, where everyone lives on their own separate plots of land and does as they please. But postlibertarians and the Grey Tribe should not cede urban policy to the left so easily; cities are largely vital for the economic reasons I’ve put forward. While today they are often bastions of progressive politics, cities are too important to be left to be governed by the ideas of a single political group.

Dense Cities

Since there are benefits to people who live in cities as described above, it seems to follow that denser cities might emphasize those benefits to a greater degree.

The economic argument seems to make sense here: if cities concentrate people, denser cities should concentrate logistical costs. That means less investment cost in infrastructure per person and less cost to deliver a larger amount of physical goods to the same people. There should be better economies of scale for transportation when cities are packed together. Another interesting benefit might be that with locations closer together, fewer people would use cars, so there would be less total hours wasted in traffic for a city of similar size but lower density. Perhaps this would be offset by longer total transportation time since walking is slower than driving. Certainly it seems that fewer people would die in car accidents at least.

Another benefit specifically for libertarians might actually be fewer road square footage per person. Roads are expensive, are often centrally managed by the city, and so don’t respond to price signalling. Optimal road work is thus not easily achievable, leading to poorly timed construction (overabundance of construction due to road opportunity cost not being priced) or not enough road repairs (too little construction due to no consumer payment for roads). Narrower streets specifically would essentially privatize space in a dense city, space that is highly valuable.

There is also a little bit of anecdotal evidence for cultural benefits of dense cities too. For example, we might expect denser cities to have more people from an odd subculture willing to meet than the population of the city might suggest (due to close proximity). As an example, let’s use Slate Star Codex’s series of local meetups earlier this year. If we expected SSC meetup populations to be based solely on total population, we’d see it match the US Census’ Core Based Statistical Area ranking: New York, Los Angeles, Chicago, Dallas, Houston, Philadelphia, Washington, Miami.

If we expected denser cities to show the social/cultural benefits to a greater extent than spread out cities, we should expect the SSC meetup populations to more closely match the population density of top cities. Unfortunately there’s no exact definition for a dense city. The simple way to define it is total population within a city’s political borders divided by the land area under that polity. However, cities usually extend beyond the political boundaries specifically because those municipal governments get in the way. If we go by this definition, the top US cities should be New York, San Francisco, Boston, Chicago, Philadelphia, and Miami. Now this actually matches the top SSC American cities pretty well, with the exception of Miami which didn’t meet the 10 person minimum despite being in the top seven cities in both total population and density. Another way we can represent density is through the number of high density areas in each metropolitan area. This yields in order: New York, Los Angeles, Philadelphia, Miami, Boston, Chicago, San Francisco.

There are obviously other factors at work in the SSC meetups including culture of the city (Silicon Valley/startup culture is probably the best predictor of SSC readers, as we see small Silicon Valley towns like Mountain View on the list) as well as a number of English speakers (explains why dense foreign cities are not high on the list), and college degrees. This last point is interesting. This article discusses how denser cities only seem to realize productivity gains in high human capital situations. Finance, technology, and other professional industries requiring higher education stand to gain from higher density cities. One question then is whether college graduates are attracted to dense urban cores or whether urbanization simply occurs around where college graduates tend to be (around universities?). To me it seems that cities clearly predate modern universities and college graduates. The establishment and growth of cities seems fairly organic, emergent, and spontaneous.

Too Dense?

This brings us to the next point: cities don’t require urban planning to exist. Humans are completely capable of decentralized self-organization of urban areas, and cities existed and continue to exist without strong municipal governments, zoning laws, building codes, etc. Nonetheless, with close quarters comes externalities, and so governments arguably have a lot of benefits to offer residents of cities over not having governments. Yet, as urban economist Issi Romem writes, American cities tend to expand outwards, and those cities that don’t expand geographically see large cost of living increases. Relatedly, as this Forbes piece points out, many of the highest density cities in the world (Dhaka, Delhi, Karachi, Mumbai) are also relatively poor. Cities can be rich, but density doesn’t seem to be a requirement for being rich. In the U.S., most new housing comes from urban expansion, not density increases. This seems to beckon that it is not only cheaper to expand at the outside of cities than it is to expand the interior of cities, but more desirable to residents. Given the benefits of cities and density, how could this be?

One possibility is that it could be more expensive to bring goods into a city center than we thought. Maybe economies of scale don’t work as well due to increased traffic. I don’t have much evidence for that, but I guess it’s possible. This seems unintuitive though, as living in the suburbs means dealing with much more driving and traffic anyway.

However, some goods don’t need to be transported into the city…like housing. Once it’s there, it is consumed slowly over time. Yet rent is fairly correlated with density. I don’t have good data on it, but I took at look at padmapper.com in a couple cities that I knew the general density of. I took the price slider and noted where the high priced places were compared to the low priced areas. It wasn’t a perfect correlation, but it did match my general feeling that more density was associated with higher prices. So if we assume that a housing market is in equilibrium, differences in price for dense and non-dense areas indicate on the demand side that there are plenty of people who would prefer to live in urban dense cores over suburbs given the same price.

Next, on the supply side, differences in price between dense and non-dense areas indicates higher marginal cost in dense areas compared to less dense areas. So what is driving that cost?

Certainly more complex tall structures are needed for dense living, although part of that cost is spread over many more inhabitants. Additionally, there is more reliance on public transportation infrastructure than is needed in the suburbs, which might lead to higher taxes to pay for it. However, other infrastructure costs are lower per person in the city than in the suburbs (lower fixed costs to build water, sewage, electrical, internet, and roads because they scale largely with horizontal distance, which is minimized in a city). Additionally, if cities are supposed to help make people more productive then we might hope similar tax rates would bring higher revenue in dense cities than suburbs. It’s hard to know then whether tax burdens should be higher in cities, but it seems colloquial wisdom believes they are (high density cities don’t seem like low tax areas). I did find this 2005 paper from Harvard indicating that multi-family buildings (apartments) had a higher tax incidence than individual family homes. Moreover, as Stephen Smith at Market Urbanism pointed out, much of that local tax money goes to roads and schools, things denser urban dwellers likely use at lower rates than suburbanites. Finally, the federal mortgage interest tax credit further makes housing cheaper for suburbanites over urban core residents.

Free Market Perspectives

So while it’s possible to say that it simply costs more to live in a dense city, it’s also true that government seems to cost a lot in cities. Perhaps that’s a necessary part of living in cities, but if we leave urban policy as the sole domain of the Left, there will be no counterbalancing philosophy that understands market forces. Without that check, government will cost more than its benefits.

Moreover, raising tax revenue and providing services are not the only functions of municipal governments: they also create regulations, which are another way they contribute directly to the cost of living in cities. Here it seems there is little nuance to be had: most high productivity cities have far too restrictive housing regulations. This has reduced the ability of labor to relocate to more productive areas of the economy, and according to this NBER paper, has allowed for massive missed opportunities in economic growth. And this makes intuitive sense; over time, technology should allow us to build denser and denser cities more cheaply, yet new housing in some of the most productive cities has not kept pace with demand. The explanation must be regulatory hurdles on new housing.

Such an outcome squares well with the common opposition to urban development known among the urban policy community with the pejorative NIMBY (not in my backyard), and it applies not just to housing, but to any development in a city. Elected municipal governments are responsible to the people who live in the city at present, not to possible future citizens. While this may seem just, it is emphatically a net negative in a utilitarian calculation; improvements in human lives should not be discounted based on where that human lives. Policy that makes it harder for people to move to a city to make it denser, when those people want to move there, creates worse outcomes than we would otherwise have.

Finally, let’s take a step back: I’m not saying that people have to live in dense urban cores; people should live wherever and however they would like to. I’m saying that governments can mismanage urban policy in ways that prevent people from moving to where they would actually want to go. Bad policy changes the nature of cities and reduces the potential benefits they can bring. Because urban policy tends to rely significantly on some state intervention, I find that there is not a plethora of free market urbanists. Nonetheless, cities are an important part of the modern human experience and they will continue to be in the future. Libertarian perspectives have much to offer urban policy and it would be a shame to abandon it to the left.

So the DEA has taken the massive failure of the War on Drugs and decided the lesson to draw was to add another drug to Schedule 1, the most prohibited category (and more tightly controlled than cocaine). Kratom, a drug used for opioid withdrawal treatment has been added to the list. The 15 deaths cited by the DEA over the last 2 years are sure to bump up as users’ legal alternative to illegal opioids is removed.

Classic example of regulation making it more difficult for simple economic transactions. This manifests in higher prices for compliance which ends up hurting the poor disproportionately. Seattle used to be the leading place for “micro-housing”, but it’s being regulated out of existence to the tune of hundreds of affordable dwellings a year.

Gary Johnson: WIRED should have endorsed me for president.

Related: Donald Trump has received no major newspaper endorsements, and many newspapers who have endorsed Republicans for decades, even centuries, are either endorsing Clinton, Johnson, or simply endorsing anyone but Trump. Some newspapers who don’t usually endorse anyone are doing so, such as the Atlantic, USA Today, and actually WIRED had never issued an endorsement. A redditor collected all the information into a nice post.

I’m not a Ross Douthat fan, but I do like this column. There’s a real sense of being surrounded that non-progressives feel. And when surrounded with no hope of making it out alive, soldiers fight to the death because they have nothing to lose. Not a great situation.

Heard through Alex Tabbarok at Marginal Revolution: apparently an author at the Telegraph isn’t happy about Mark Zuckerberg’s plan to eradicate all disease. She’s apparently afraid of the impacts of overpopulation. And she published it. In a real newspaper. So if you’re not optimizing for the “most good” in the world or most “human happiness”, what exactly are you optimizing for? If the author is so concerned about human population, does that mean she’s generally pro-war? Is she pro-Ebola? Anti-CDC? What are her feelings on ISIS? Does she have suicidal thoughts? I just have so many questions.

Seen through Slate Star Codex, the Brookings Institution has a report on charter schools in Massachusetts: “There is a deep well of rigorous, relevant research on the performance of charter schools in Massachusetts…This research shows that charter schools in the urban areas of Massachusetts have large, positive effects on educational outcomes. The effects are particularly large for disadvantaged students, English learners, special education students, and children who enter charters with low test scores. In marked contrast, we find that the effects of charters in the suburbs and rural areas of Massachusetts are not positive.” I’d guess this is because in the suburbs, the schools are already pretty good and must compete with expensive private schools anyway.

Forget moving to New Hampshire, the new mayor of Johannesburg is a self-proclaimed libertarian.

Why are American airports so crappy compared to international ones? Well it’s partially because most American airports cater to domestic flights and are not international travel hubs. Airports that focus on similar levels of domestic travel resemble LAX more than Dubai, LaGuardia more than Singapore.

Jacob Levy at Bleeding Heart Libertarians writes that if you look at the polling numbers, Johnson doesn’t draw more from Clinton, and having him on the ticket actually helps her.

Obviously this election cycle has been particularly divisive and nasty. But did you know there are people working on fixing this? Check out the National Institute for Civil Discourse’s Standards of Conducts for Debates. Can you imagine if the political debates were actually like this? I might even want to watch them.

Megan McArdle on How to End the Death Penalty for Good. There’s an interesting point about how abortion laws were on the decline and probably would have quietly died except for the Supreme Court stepping in and making the decision themselves. This galvanized social conservatives into organizing themselves and mobilizing to protect their interests against perceived undemocratic justices. I’m not sure how accurate that is, but it’s certainly true that “judicial activism” has been reviled by the American Right for a while now.

A good rundown by Reason of their staffers and many prominent libertarians on who they will be voting for. Dave Barry’s response is by far my favorite.

There is a storm brewing in the Libertarian Party. Gary Johnson will likely meet the 5% threshold set by the FEC on who qualifies as a minor party. That means the LP will be eligible to get taxpayer provided funding for its candidate in 2020. There are two problem. One is that Libertarians are fundamentally opposed to this practice, and taking the money would make them look like hypocrites. The other is that neither party seems to take matching funds anymore as it also puts a cap on how much you can raise. That cap scales, so the cap itself may limit the LP in the 2020 election.

Counting past infinity is easy! It was the infinity raised to infinity and infinite number of times that I really got lost.

I’ve settled on the right way to show the date in these links posts: the international standard ISO-8601. It’s about time since that has been the standard since 1988.

Niskanen center names social justice aware libertarianism as “neoclassical libertarianism“. I like this idea, as it’s strictly superior to progressivism, and I’ve been trying to come up with a good name for it. Scott Alexander called it left-libertarianism-ist, which just isn’t as catchy. Of course, maybe pure libertarianism is better, but neoclassical liberalism is far more politically palatable. It is also more “conservative”, meaning that it is closer to the status quo.

Merrick Garland would not be a good SCOTUS justice. Randy Barnett discusses with Reason why he opposes Garland’s nomination: he’s completely deferential to executive and legislative authority and does not protect individual rights from the state. Does it make sense for the Senate to not give him a hearing? Maybe, maybe not. Did it make sense to declare prior to his announcement that any candidate wouldn’t get a hearing? Hard to say; if that hard line approach made Obama nominate an old white guy who endorses state power in the name of national security, that’s certainly a win for neoconservatives. I don’t think anyone should take an outrage stance on the Supreme Court opening because this really is a complicated game theory situation with nested layers of strategy. Even though I’m sure he is one of the most un-libertarian nominees ever, it’s impossible to say if he would be worse than a Hillary appointee or even a Trump appointee.

Heard through Slate Star Codex, anti-censorship blog Status 451 (linked in the sidebar) held a fund-raiser for LambdaConf, a functional programming conference I had no idea existed until a week ago. Apparently, after an anonymous analysis of submitted papers, the Lambdaconf organizers selected a paper to be presented at the conference by Curtis Yarvin, a.k.a. Mencius Moldbug, perhaps the most well known neo-reactionary. Certainly I think neo-reactionaries are a bit nuts, but Mr. Yarvin has also invented the intriguing functional programming language Urbit. We don’t agree with him politically, we can learn and grow our knowledge by understanding what he has to say, especially in technological areas he is an expert in! Alas, as Eric S. Raymond recounts, the social justice movement did not see it that way and pressured LambdaConf to remove Yarvin from the event. Lambdaconf refused and the activists moved to forcing sponsors to drop out. Incredibly, Status 451 started an indiegogo campaign to save LambdaConf, which was funded within the day. This is a big victory for anyone who wants to live in a tolerant, knowledgeable, and free society, but if you want to know their motivations firsthand, please read what they have to say. Status 451 are also true believers, calling out some on the right for their similarly censoring response.

Apparently the music industry thinks the DMCA doesn’t do enough to stop copyright infringers (more on the RIAA at TorrentFreak). It seems they’d like to target the safe harbor provisions of the DMCA, the only parts of it that are useful. Techdirt has a great series of posts from the other side, detailing the many abuses of DMCA takedown notices. Right now, there is no legal check on whether a takedown request comes from someone who actually owns the copyright, or even if that copyrighted work is utilized fairly for criticism or commentary. This isn’t an easy problem to solve by any means, but we should remember that the point of copyright is to encourage production of new works, and if there’s anything that YouTube does right is making it easier to create new content. Moreover, it’s helpful to remember that YouTube is run at a loss of more than $150 million a year. Trying to force YouTube to pay for content policing is one of the dumber ideas they’ve ever had, which is saying something. So what should be done instead? A good start would be to make false copyright claims a criminal offense, and require you to prove you own the copyright in the claim. It would also be good if it turned out your copyright claim was wrong, the ad-money would not go to the claiming part, but would be held in escrow until the dispute is resolved. This would allow YouTube to better focus on actual infringers and stop the torrent of false claims. Of course, another big looming problem for the RIAA is Facebook video, which doesn’t even have the semi-transparent (though flawed) takedown-notice system of YouTube. Ultimately, given how little money YouTube makes after 10 years on the internet, if YouTube was allowed to be held liable for infringing uploads, YouTube would either go out of business, or cease becoming a free platform anyone could use. This would be a monumental failure of the copyright regime; yes, it might end up getting RIAA members more money, but that is not the purpose of copyright. Copyright exists to help make new content, not destroy content platforms.

California is raising its minimum wage, eventually to $15 an hour. FiveThirtyEight’s Ben Casselman is excited at least to get some data on large minimum wage hikes, although judging from the headlines, it seems like he thinks this is a good idea. I’m fairly confident it is not, and Matt Zwolinski makes one good point to support me: the minimum wage doesn’t fight poverty. There’s a lot of data surrounding the minimum wage. And it’s apparent that unemployment does not automatically rise when minimum wage increases occur. Nonetheless, longer term unemployment effects are essentially impossible to study, and it’s likely there are some effects on businesses. If businesses could absorb 20-40% increases in labor costs easily, then why aren’t businesses getting more out of their employees, or more firms entering the business due to excess profits? There is evidence of long term job growth being harmed, as well as higher prices (see last link). Ultimately, I predict there will be negative consequences for California, but it’s hard to find something that is worth predicting. I could predict that California’s employment and workforce participation rate will be lower than the country average by more than they are now (check this in the future). It’s also likely that low cost goods will see price increases, but I don’t have an easy way to check that over the next five years.

Robin Hanson has a good thought experiment to show that most people don’t vote to change the outcomes of elections. This would explain why anyone votes at all, given the uselessness of voting generally.
