https://twitter.com/DAcemogluMIT/status/1659593970580701190Intelligence is not binary. Humans are very good at say 10,000 cognitive tasks (the specific number is made up). GPT-4 is very good at 50, and superhuman at a handful. Subsequent models will be more capable at a broader range of tasks.

https://twitter.com/ChadJonesEcon/status/1651219721205977088I especially like that @ChadJonesEcon considers the value of potential mortality reductions from AI, which seems essential and overlooked in this debate, and that now needs to be integrated with the considerations above.
https://twitter.com/danascoot/status/1651406474889900034A cardinal and understandable mistake that grad students make is to think: "I have been working on X project for 2 years and it is my first project. If I don't have a paper, I have accomplished nothing. So, I'll keep trying to write a paper I know should not be written."
https://twitter.com/mjs_DC/status/1641438679460872192We know that cost-sharing leads people to indiscriminately cut back on care. They don't just cut back marginal stuff -- they also do less of valuable stuff. We saw this in the RAND experiment (below):
https://twitter.com/Jabaluck/status/1639666515396968452The value of rewarding innovations likely to make AI safer seems very high to me given recent developments (although I completely agree with everyone who emphasizes *uncertainty* both about AGI timelines and consequences).
https://twitter.com/LizHighleyman/status/1625193937853124608The underpowered studies often have extremely low compliance. You might say, "Ah, doesn't this mean masks don't work in practice because no one complies?" No, because sometimes there is high compliance -- but it's not achieved through the methods in the underpowered RCTs!
https://twitter.com/BallouxFrancois/status/1620265902133633025There are two main deficiencies: a) the vast majority of these studies used only self-reported mask-wearing data. In most, there was likely almost no change in mask-wearing between treatment and control groups! b) community and individual effects conflated
https://twitter.com/LeemoreDafny/status/1619056792352468993In a very simple model where every drug has the same value for everyone, we ignore substitutes, etc..., dynamic incentives are optimized if the price that pharma companies receive is exactly the value generated (then PDV(profits) = PDV(social surplus)).
https://twitter.com/ASautmann/status/1603410953181270020In our current design (pre-pilot), patients will be randomized to providers of different skill levels (community health workers, nurses, local physicians) with or w/o an AI designed to imitate docs. Then the same patients will see a second provider, a local physician.
https://twitter.com/ShengwuLi/status/1565025221010006016Surely, we can recognize the difference between a researcher who is mostly trying to figure out if costs exceed benefits and an advocate with strong incentives to decide in one direction who occasionally lets themselves be swayed by the evidence only when it is incontrovertible.
https://twitter.com/MargRev/status/1562336292100513792Tyler's response here strikes me as (uncharacteristically?) overconfident about his ability to forecast politics. If congress today debated a min wage, would labor unions largely get their way or would Kyrsten Sinema push for a small increase?
https://twitter.com/bryan_caplan/status/1559924345748611073BRYAN: people want to work, but only if they get paid enough. Firms want to hire workers, but only if they're not too expensive. The market wage is the wage at which the # of workers that firms want to hire and the # of workers who want to work is the same.
