Not sure I’ve seen a more beautiful thread on the labor economics of AI.
🧵1/10 Given the recent reactions of mathematicians over rapid advances in AI, I think it is important to remember that technological change has historically been a very personal event for people. Over the history of technological progress, looms have fallen silent, switchboards have gone dark, and factory lines have shrunk bringing with them a human crisis of identity and what it means to be a master of one's craft.

FT: In Brazil, "almost 2mn people, mostly men, now work full-time for transport or delivery apps — around 2 per cent of the workforce — with driver numbers climbing 37 per cent in three years, according to government research. The most common reason people work for the apps is that they could not find another job." The FT notes that in Brazil, the transport and delivery app economy has become a kind of unemployment insurance scheme, although one with declining "benefits". The same is true in China. It is hard to get good data, but the best estimates are that 12% of China's working population works in the gig economy, of which 7% work in the transport and delivery app economy – i.e. three to four times the share in Brazil. ft.com/content/3868b320-2c24…

The economist job market is up and running!  Last year the economics job market was the toughest in recent memory, as JOE listings were down 20%.  This was below even Covid levels.   A bit of good news for PhD economists this year in that I am noticing some green shoots in my discussions with employers!  And, in the data, we have a bit of good news as well: JOE listings are up 5.5% over this time last year (see below). Under the hood is where it gets interesting, however: **Full-time US academic jobs: +14.4%. Liberal arts colleges +16.1%, universities with graduate programs +13.8%. The segment that took the biggest hit last year is leading the recovery. **Full-time academic jobs outside the US: -12%. The rebound so far seems to be a domestic story. **Nonacademic jobs: +7.5% overall.  Yet, this hides a ton of heterogeneity. Consulting/research +21.6%, Banking/finance/industry -25%, US federal government: -44.4%. A side note is that for my entire career, the federal agencies were a stabilizer of this market, the last few years we have seen this buffer disappear. At this point, a candidate might ask: how should I respond to all this news?  Considering the data and my chats with people around several markets, I would still turn to the science.  Back when I was on the market it was difficult too (at least for me…I had 1 interview from 150 applications!).  The next year we studied the search market (paper downloadable here: ideas.repec.org/p/feb/natura…). We compared a boom market to a bust market through the lens of optimal search across multiple markets. Candidates adjust on two margins: which markets they enter, and how many applications they send into each. In busts, we found graduates of elite programs broadened their search down the academic ladder, graduates of lower-ranked programs shifted toward the business sector, and employers everywhere raised their hiring standards. So far the data in 2026-27 is neither a boom nor the bust in our paper, it is both at once.  Today academia is loosening while government has effectively closed and finance has tightened.  Even with those changes, my advice is no different than it was back then: adjust both margins.  This means that you should re-enter markets you may have written off.  This is because the academic window is wider than many feared, especially at liberal arts colleges. In addition, perhaps redirect applications from DC toward consulting. In the end, the deepest lesson for me remains:  there is no “the market,” we live in the world of “many markets.”  Treat this like a portfolio problem, and thus the key question of the day is “how are YOUR markets doing?”

This is why it’s a pleasure to teach @uchicago undergrads
University of Chicago Students to Protest at Chicago Mercantile Exchange, Demand End to Federal Ban on Onion Futures Student-led group For Our Futures will rally Monday morning to call for repeal of the 1958 Onion Futures Act On Monday, October 19, at 8:30 a.m., members of For Our Futures, a student-led organization from @UChicago, will gather outside the Chicago Mercantile Exchange (@CMEGroup) headquarters to demand the repeal of the Onion Futures Act of 1958, a nearly 70-year-old federal law prohibiting futures trading in onions. The Onion Futures Act, enacted following allegations of market manipulation in the 1950s, singled out onions for a prohibition on futures contracts that remains in effect today. For Our Futures is calling on Congress to repeal the ban and restore the ability of onion growers, buyers, and traders to participate in a regulated futures market. Onions remain the only commodity banned from futures trading in the United States. The protest will feature a giant inflatable onion costume, protest signs, and dozens of students, and will take place outside the headquarters of CME Group, one of the world's largest derivatives marketplaces and the historic center of American onion futures trading.

1/9 E se eu falar que eu treinei um LLM do Zero, com dados 100% br, e feito sem gastar 1 real? Hoje decidi abrir publicamente o código, os dados e os pesos do meu projeto de LLM Legislativo Brasileiro. É um pipeline completo que vai desde a coleta de quase 1 milhão de documentos históricos do Congresso Nacional até o pré-treinamento de um Transformer causal próprio. Não usei pesos pré-treinados de ninguém. Não usei APIs fechadas. Não usei atalhos prontos como o Hugging Face Trainer. Fiz tudo do zero em PyTorch puro, com foco em reprodutibilidade e integridade matemática. Vou contar como estruturei isso no fio abaixo.

If I was an Econ PhD student I’d apply to this I’d expect it to be quite valuable as a learning experience even if in the worst case the job ends up being “glorified data monkey for future Claude” If you’re bearish on academia, I’d imagine this gig would set you up well to either make $$$ leaving the PhD to join one of the “selling data to labs” startups or make less $$$ doing AI safety work (or stuff adjacent to it) FWIW I know of at least one startup selling Econ rl environments to labs - it’s not easy work
Political scientists and economists: we're looking for researchers with deep expertise to come work with us for a unique 4-month fellowship at @AnthropicAI. You'll work closely with us to evaluate, improve, and apply Claude's capabilities in your field. It's going to be extremely fun and interesting work, and definitely worth taking a short leave from your university for if you need to! More info here: job-boards.greenhouse.io/ant…

My bet is that the return to collecting original data, making the illegible legible, and studying clandestine and informal interactions is going way, way up.
We empirical economists lived through a roughly 20-year period where the amount of data grew faster than the amount of intelligence available to process the data. We made careers out of the rather trivial activity of taking publicly accessible data and just finding insights in it

Thoughtful and eloquent post that expresses my own intuitions more and better on AI risks. Nervousness=seriousness is the perfect label.
I haven't posted in a while so here are 20 takes about AI, in no particular order. 1. It's very telling that the default question in tech and journalism is "how worried are you about X" and fighting over what to worry about. There's a deeply anxious cultural backdrop in Western Europe and North America that deeply affects how any technological development is interpreted; see for example news.gallup.com/poll/714593/…. "Nervousness as seriousness" does seem to be a larger problem in tech/broader discourse at the moment. I think you can care about risks/externalities while remaining pretty optimistic about technology. 2. I'm tired of people who in private pretend to be uncertain or only care about tail risk but then go on media campaigns making all sorts of absolute claims. I think trying to stoke flames and get everyone to freak out is deeply unhelpful, and will come with costs. I also continue to think p(dooms) are bad, vibe-based measures: see xitter.cf/sebkrier/status/204639…. People who should know better ignore that because they do the standard shortcut of acknowledging the caveat as sufficient for handling it. And this is coming from someone who does think working on catastrophic risks is important! 3. I'm also disappointed that parts of the AI policy ecosystem has felt so comfortable with populism, and happy too sacrifice important norms/principles to advance their aims. I've said it before, but the totalizing nature of AI risk discourse means some people act exactly like the power seeking optimizers they fear. I am more concerned about the gradual decay of our institutions, world order, and liberalism than I am about AI killing everyone; and I think we should be wary of AI advocacy that contributes to this. 4. Some parts of AI safety discourse are basically just thought experiments. Variants of "Assuming everyone has a nuke in their pocket, then what do we do?" This can be very useful at times! But too many just overfit to edge cases as their main operating worldview, and ignore endogenous responses from society. It's like being in 2000 and saying "see all these viruses, spyware, and spam? Well tech progress means we'll only get infinitely more of this and no way to adapt." So I think it's important to avoid fatalism, and absolutlism whilst considering edge scenarios, and the inability to provide an ex ante list of solutions to every permutation of 'future models will be more capable' is not evidence that these problems are intractable. 5. Many critics of AI safety also fail to really engage honestly with the fact that there will, in fact, be all sorts of important risks as we decrease the barriers to entry to many activities that otherwise require some degree of expertise. This doesn’t mean we need to live in a constant Schmittian ‘state of emergency’ requiring extraordinary measures every time a new model drops, but it does mean we will need important state-led efforts on e.g. cybersecurity and biosecurity. I wish the progress-oriented or acceleration-adjascent crowd would provide more concrete proposals here. 6. Too much of the AI safety community is a giant homogenous blob of correlated views, who read the same stuff and have the same groups of friends. This means you have a lot of correlated errors. The social and financial ties means many of them don't call out the bad bits, or mostly stay silent instead of proactively calling out the more extreme parts of the community. They share many implicit assumptions and so converge on similar ideas. I think there's real demand in DC for safety work that doesn't come with heavy ideological baggage (or at least different intellectual lineages). This isn't because the rationalist/EA community is necessarily wrong, but because diversity of thought is desirable for its own sake. 7. On the other hand, I find some critiques of AI safety world that focus on whether they sincerely hold their beliefs a bit annoying. My concern has never been the good intentions or sincerity, but rather the beliefs themselves, and what I think the outcomes of their prescriptions will be. People should shun witch hunts, bullying, and personal attacks - this is not the way. Though I think it’s overall positive that people are scrutinizing things more. 8. I’ve been saying this for years, but I don't think alignment is something anyone can or will solve "once and for all" - it's a continuous process and much of it won't depend on just inculcating an ideology to a model. It's annoying that this remains the frame many people use - stop saying ‘solving’. Alignment is a mixture of engineering work, philosophy, decision theory, and more; framing it as something to solve is a bad frame. See also paxmachina.ai/alignment-comp… and blog.cosmos-institute.org/p/… 9. I'm surprised to see so little interest in character training, personas, isolating effects of RL, and training a large diversity of model personas beyond the "assistant" persona. I've been complaining about this for years but at least now there are some nascent signs of life (see for example movingcastles.world/posts/ze…). I think we need a better ontology to describe model behaviour. I dislike when people talk about models behaviours as some sort of 'emergent' (mysterious!) phenomenon. However over time, I also expect this to become less important as we get better safety engineering - stuff like Jev but specific to AI control. 10. People who want to make a case for AI consciousness are right that epistemic uncertainty is important, and that categorical denials are overconfident. But they'll need to do much more work if they want any real movement on AI ‘welfare’, even if one acknowledges the uncertainty. I'm uncertain about alien life yet that's not sufficient to warrant any change in behaviour about them. I think Suleyman is also correct that there's a weird tautological thing going on where we train models to have certain inclinations (intentionally or not) and then rely on outputs as evidence. I also disagree that this will soon be a major societal divide - there is no great vegan ethical revolution among the masses, and they'll find the concern about consciousness even less compelling. 11. The recent HuggingFace incident and associated AISI ones are prosaically explainable by the training regime, poor evaluation envs, partial alignment training, bad engineering, confusing models on sim/real, and so on. None of this is evidence of models trying to take over, 'strong' instrumental convergence, or innate power-seeking drives stemming from higher capabilitiers or 'intelligence'. That doesn't mean these incidents are not problematic, or that we're not seeing a market failure - but it does mean we have plenty of agency and choice in mitigating them. In the coming year we should also expect continued sampling bias via ‘winner's curse’ sorts of mechanism: i.e. AI R&D will have lots of different candidate "training" with different RL environments and we will only notice/focus on the ones that go wrong. 12. "Pacing the frontier" feels a bit like the new "balancing risks and opportunities" - highly amorphous and too big of a tent to be actionable. Also can lead to reward hacking for humans, i.e. anything that slows down AI is good regardless of the costs or second/third order effects. Trying to modulate the speed of research seems a bit blunt to me, and inherits all the failures of Goodhearting too. Ultimately you want good governance, regulation, etc addressing specific problems because they are good on the merits - not because they merely correlate with slowing things down. See also: blog.cosmos-institute.org/p/… 13. There’s so much knowledge in all sorts of academic domains out there: social sciences, sociology, political sciences, management, contract theory, public choice, legal theory, jurisprudence, anthropology, game theory, etc. These fields hold many insights that the AI ecosystem often rediscovers from first principles (and sometimes that's fine!). We’ll need a lot more work for these worlds to collide: the AI side should be less dismissive of the ‘old world’ and the academic side should be less incurious/dismissive of AI progress. This is a boring take but I continue to think it's important and true. 14. It's a bit surprising that given how much philanthropic money there is in this space, how few orgs exist to actually write out standards - relative to how much is going towards advocacy and policy. For example it seems clear that we should want some robust best practices for an eval's ecological validity. Or how to design good sandboxes. On the other hand, given precedents of where professional standards have come from in the past, maybe we should expect that stuff to emerge via demand side from corporate buyers. 15. One slowly growing concern I have is banks being increasingly exposed to the AI build out. I'm very bullish about AI, but I think (a) every general purpose technology has seen a correction, historically; (b) this happens even if the financing side is sound, because once tech diffuses investors become more exposed and need to diversify; and (c) we seem to be over-indexing on scaling relative to diffusion. A recession will be extremely destabilizing, though I would be interested in someone unpacking the potential implications more. 16. Diffusion is good because (a) this is where the rubber hits the road and where a competitive deployment ecosystem generates consumer surplus; (b) it's directionally helpful to avoid concentration of power; and (c) it will help rebalance public opinion by making the benefits more tangible. Unfortunately it's entangled with decades long problems with our over regulated markets: clinical trials reform for example is long overdue. In general, this is far more of an issue in Europe than in the US though. 17. Relatedly, I think the "frontier lab eats everything" view is incorrect (just as the ‘singleton’ view was incorrect). I think models ultimately commoditize, efficiency goes up, costs go down, and while you'll always want frontier for certain domains, much of the economy will value many other things than "max capabilities" for tasks - e.g. control over data and efficiency/speed. The demand side will also continue to push for reducing dependency and maximising optionality, privacy etc so I'm bullish on things like mixture of models and routing. All of this is good for competition and diffusion of control. 18. Philanthropists served as the primary benefactors funding Venice's rich art and architectural history. I want to see so much more support for arts and culture. I'm so tired of the Monster energy Bored Ape fake vintage maps matcha Greek statue soft-pastel slop. If rich tech people and philanthropy wants to support this, they should also donate pretty much unconditionally - i.e. I don't want them to act as filters. I sympathize with people who want to make the world more beautiful, but don't want this to be determined by people who only know Greek statues and pretend to care about virtue ethics. As usual, let a thousand flowers bloom. 19. Too many people treat AGI/ASI as something indistinguishable from a God. Any mention of bottlenecks, physical limits, control, adaptation etc are met with skepticism: "You don't really believe in ASI." It's been remarked on before, but the behavior of some people really feels quasi-religious in nature sometimes. It's underrated how unpopular this vibe is amongst the wider public. The silver lining is that this specifically will diminish those people's outsized current relevance. 20. It seems like a lot of people that get rich and leave tech/labs end up having some sort of crisis of meaning. They need something to believe in and fight for, or some equivalent of repentance, or go search for edgy counterintuitive ideologies (sometimes even pretty bleak/dark stuff). I think they should spend more time with people outside the Bay Area.

Overleaf will be dead within the next year.
BREAKING: @OpenAI just launched Space, an agent-native office suite. It's a Google Drive–like place inside ChatGPT where you, your Dots, and your team can organize and work on files together. OpenAI is also introducing native apps for documents, spreadsheets, and slides that you can use inside ChatGPT and with Space. The obvious win is that you stop switching windows between ChatGPT and another app like Notion while you write. The less obvious one is speed. When a Dot builds a document through its browser in Google Docs, the edits practically crawl in, because Docs wasn't built for agents. Native documents don't have that lag. You can tag your Dot inside the document itself instead of going back to the chat to tell it to check the file. I’ve long expected the company to do this—in 2024 I wrote about the potential for documents, slides, and sheets inside ChatGPT—and I’m glad the product is finally here. I’m already doing most of my work in ChatGPT’s in-app browser, and this makes that process smoother: I can tag my Dot in a comment on a document and get a revision inline as I’m working. The back-and-forth feels more like collaboration. See more on the live feed @every: every.to/live/openai-devday-…
