The sense of knowledge and enthusiasm loss is very touching...
The writer's honesty is admirable h/t @odavis_h and @theStalwart
We obviously haven’t had the major jobs wipeout yet. But you read stuff like this. And you read what economics students themselves are saying about working with AI (ht @odavis_h) and it’s hard not to feel like the seismic shift is on its way.

.@markmuro1 from @BrookingsInst had much to offer on #DataCenter

Research fact from the essential @TimBartik:
Reformed state economic development policies carry large benefits.
In fact, reforming these policies can make money for state and local governments.
So let's do it! @Rohan_Sandhu
My report on reforming state incentives released today. 5-page summary: research.upjohn.org/cgi/view… Conclusions: current incentives have modest returns and large costs. Reforms that use more cost-effective services & target distressed places & reform housing can increase returns 6x

Many people who work closely on AI and are constantly seeing charts like the one on the left (AI capability growth) think that it will translate to the graph on the right (GDP growth). But the economy is much more complicated than that.
Absolutely: We need to shift more effort from the capacity drive to the use-case drive.
Good piece by @bethnoveck recently in the NYT: "We’re so busy debating whether A.I. will destroy humanity that we don’t ask how we might use it to deliver services, run elections, make laws and better listen to constituents."

🚨 Public good alert: I put together a list of 100+ free datasets for social science research, spanning a large number of topics.
I hope it's useful for students, researchers, and anyone looking for interesting data to explore.
Contributions are welcome! github.com/toddrjones/datase…
This from @stephenwitt is smart on the divide between GPU engineering types and "software guys" as an explanation of different worry levels on AI.

Several facts regarding the AI bubble question that are all true at the same time, with most points illustrated by graphs
1. AI revenue growth is incredible, and possibly historic.
2. Big public tech companies have relatively low P/E ratios right now, which defies lazy predictions about how they're wildly mis-priced and doomed for a big correction
3. But model competition could compress AI token margins ...
4. ... at the same time that the hyperscalers are going deeper and deeper into debt to build out AI ...
5. ... and the level of future free cash flow anticipated to justify this build-out is absolutely enormous, like genuinely without precedent in corporate history ...
6. ... and any correction in frontier lab valuations will reverberate through public companies, which own huge shares in the labs
Wow! Have to think that topline is sucking emp growth out of those other lines!
@dgoetzel @GlencoraH
Here's a needed overview: @alexolegimas and @FutureEconJacob ask if #AI has hit the labor market yet: Their verdict is not yet in aggregate
Unemployment and layoffs show almost nothing. But AI may be cutting junior hiring in exposed white-collar jobs. Remote work part of it
Has AI hit the labor market yet? @alexolegimas and my verdict after ~20 papers: not yet in aggregate. Unemployment and layoffs show almost nothing. But AI may already be cutting junior hiring in exposed white-collar jobs. Remote work may explain part of that decline.

Perhaps the best evidence for AI-driven arts job loss is that all digital arts industries are losing jobs while most live arts still chug along
Sectors like graphic design, streaming, & movie recording have experienced historically unusual job loss since ChatGPT's launch
Ah thanks @TheStalwart: I guess we forgot it's not all savings and efficiencies!
The Blue Cross/Blue Shield Association says that AI is already driving *up* healthcare costs, as hospitals use the technology to find instances where they can bill more for the same level of care. bcbs.com/about-us/associatio…
Worth a look: @SVNieuwerburgh details in @BrookingsInst Papers on Economic Activity how the "intangible revolution" of #AI is also a "large-scale infrastructure investment cycle."

Both theory and practice are pointing in this relatively slower diffusion direction, which would help reduce disruption to some extent (if it plays out)...
This is a good explanation for why we're not going to get sustained double-digit economic growth no matter how fast AI capabilities improve. The demand point is particularly important IMO. aleximas.substack.com/p/will…
