Bad leaders. In the U.S. case, symptoms included increasing dementia, having a news anchor as secretary of defense, and purging top military in favor of sycophants.

So let me see if I understand . . . Brazil-Morocco is tied, but which one of them has possession at the 37 foot line? And someone is at the line for free throws in Qatar-Switzerland?

This is a great graph. The point is not time. The x axis is gdp per capita. The point is that growth does benefit all. The idea growth only benefits the rich is dramatically false. timely given Stieglitz, Pketty et al recent degrowth noise.
A way to see the amazing history of economic growth and declining poverty over the last two centuries.

Central planning in America, who would have thought?
The new OMB grant rules are being sold as anti-DEI reform. They are much worse: a government-wide machinery for political control of science. Every award must advance “the President’s policy priorities.” Peer review becomes advisory. Grants can be killed on political whim.

These names sound familiar somehow, like I've seen them in a very similar context before? 🤔
No, you are Bond Villain communists who hate human flourishing. Perhaps you used to be economists.

I had blocked Elon. And when I look, Elon’s Tweets are worrisome. He knows very little about the real world, and has adopted a paranoid and delusional worldview beyond the companies that he presumably knows well. He needs to get out more.

It's funny how this essay about matchmakers feels like a sort of fable about technology and work—even AI and jobs Step 1. Online dating makes something measurable—matching—more efficient. Step 2. People predict that, obviously, this will put matchmakers out of a job. Step 3. But increasing the measurable thing, matches, also increases the annoying thing, bad matches, and that makes people frustrated, Step 4: Frustrated people with money pay matchmakers to improve the process. Ta-da: Technology to increase digital matchmaking ironically increases the demand for human matchmakers (cc @alexolegimas)
Replying to @stephmurrayyyy
At one point, people thought online dating would put matchmakers out of business. That seems pretty silly now! Everyone I spoke to thinks online dating is actively generating demand for their services.

How likely is this recent research boom to collapse soon? If I read the papers will I know?
👇 Great to see the "bubble literature" developing and making some important steps forward! (Can someone write it in cts. time?)

It is wonderful to see how a perpetual NBA basement dweller defeating NBA royalty and on the verge of a championship unifies a city in celebration. (And makes trolling NYC friends maybe even more fun :)

When someone online has "LLM" after their name, does that now mean that they are an agentic Large Language Model?

“Social Security’s 75-year solvency gap has grown 16% relative to last year’s projections, from 3.82% of payroll to 4.42% of payroll. Over half of this deterioration was due to lower projected fertility rates while a third was the result of lower assumed immigration.

Excited to see this out! We come up with (AFAIK) a brand new way to solve for market-clearing prices: target an imbalance of zero like a moment condition. We expand the state space to include parameters and prices, so we can estimate and clear markets after solving the model once

The USDA funded research on the sex life of the screwworm. Screwworms were a cattle parasite in the southern US. That researcher developed the sterile insect release technique, and, by 1966, the U.S. was declared screwworm free -- saving ~$20B for US cattle producers. 3/

Remember in May 2017 when Trump established, by EO, the Presidential Advisory Commission on Election Integrity? I can't find the report detailing election fraud in the 2016 election. Oh, wait. Trump disbanded the Commission in 01/2018 before it could report no evidence of fraud.

If you watch the President, not the crooked media’s reports about this clip, you can hear in his own words that this President knows the truth by looking. He neither needs nor has evidence. And is frustrated by Americans who question his incredible abilities.
WOW -- Trump crashes out and cuts his interview with Welker short as she presses him on his lack of evidence for claiming elections are rigged "You're either crooked or you're stupid. Let's call it quits. Because I've had enough. Thank you darling," he tells her." "I traveled all the way to Wisconsin for this interview," she pleads.

The President is not well. He can’t stay awake at important White House events and cabinet meetings. @WhiteHouse needs to come clean about why trump takes so many trips to the hospital and why doctors keep giving trump cognitive tests.
Trump appears to be completely passed out asleep during his 3pm Oval Office announcement
