First order of magnitude given low median investment on health, education, infrastructure, etc it doesn't seem like population is a global constraint.

Of course, Ethnocentric limits on migration *do* conjure local problems, but those have direct solutions. 1/

Machines don’t rebel, they redistribute.
Minniti, @klausprettner.bsky.social‬ & @franceventurini.bsky.social show in EER that as #AI grows across #Europe, labour’s share of #income declines, especially among the educated.
This is a precise and profit-minded revolution.

We show how the deployment of #AI affects the #wages of low-skill workers and high-skill workers. According to the results, AI may reduce wage #inequality.

Many thanks to the editor Samuel Vigne and the anonymous referee for many helpful suggestions that helped to improve the paper.

"Economists across a broad ideological spectrum argue that investments in scientific research — especially the kind of fundamental, early-stage research that is too risky to attract private investors — are among the most efficient uses of taxpayer dollars."

Ben Casselman @bencasselman.bsky.social · Mar 31

Tariffs get all the attention, but ask economists what they're really worried about and many will point to the Trump administration's cuts to federal support for the sciences, including canceling grants and revoking student visas.

"We can heal the sick and save children’s lives, all inexpensively... We properly honor a firefighter who saves a single child, but three cheers for us as taxpayers for rescuing millions of children around the world from AIDS, starvation and disease.

That is, until January."

Opinion | Musk Said No One Has Died Since Aid Was Cut. That Isn’t True. (Gift Article)

A journey through the front lines of global poverty shows that when the world’s richest men slash aid for the world’s poorest children, the result is sickness, starvation and death.

Zelensky is a wartime leader watching his people suffer and die under Russian attacks every day. To be lectured and lied to by Trump and Vance, as they defend the war criminal dictator committing these atrocities, is unimaginable agony. An everlasting shame for America.

Trump has not uttered a critical word about Putin but he and his VP publicly belittled the leader of the nation Putin invaded.

I will never forget the photo of Zelenskyy’s face after he saw Russia’s war crimes in Bucha in 2022. He seemed to age years in an afternoon. Watching him constantly cross the world asking for aid that should have been thrown at him is one of the deepest shames of our age.

An attempt by the popular video-sharing app TikTok to assuage EU lawmakers' concerns backfired yesterday, as company executives faced hostile politicians questioning its role in ultranationalist Călin Georgescu's win in the recent first-round of Romania's presidential election.
