In a famous paper, some economists estimated the annual value of the whole biosphere's ecosystem services at $33 trillion per year.

Michael Toman quipped that this is "a serious underestimate of infinity".

recent Axios story on maternal health policy referenced
"findings" that a majority of people trusted their doctors and nurses. On the surface, there's nothing unusual about that. What wasn't originally mentioned, however, was that these findings were made up.
Clicking through the links revealed (as did a subsequent editor's note and clarification by Axios) that the public opinion poll was a computer simulation run by the artificial intelligence start-up Aaru. No people were involved in the creation of these opinions.
The practice Aaru used is called silicon sampling, and it's suddenly everywhere. The idea behind silicon sampling is simple and tantalizing. Because large language models can generate responses that emulate human answers, polling companies see an opportunity to use A.I. agents to simulate survey responses at a small fraction of the cost and time required for traditional polling.

Please read this article to the end. Even before ICE got involved, this started because this *blind man who speaks no English and uses a curtain rod as a walking stick* got lost on a walk and some Karen called the police on him and they tasered and beat him bc he didn’t drop the rod. WTF

‘We’ve Got to Kill and Kill and Kill’ | Dan Kaufman As Francisco Franco’s reputation grows on the far right, a new history of his regime reminds us of its unrelenting violence toward Jews.

I have an essay in @nybooks.com about a compelling new book by Paul Preston, a masterful British historian of 20th- century Spain. Deepest thanks to the remarkable editorial staff at the Review for all their help.

Trump’s Campaign to Defund the Arts—and Rewrite History "The campaign to defund the arts, capture our museums, and rewrite our history is a prelude to silencing dissent."

The campaign to label art "too woke" or "too liberal" has dark historical echoes. In my op-ed, I draw the parallel to Nazi Germany's "Degenerate Art" exhibitions and the Soviet doctrine of "Socialist Realism." When a government dictates what art is acceptable, we are on a dangerous path.

Kennedy’s Vaccine Panel Votes to Limit Access to Covid Shots

I cannot overstate how remarkable it is that under GOP rule, US federal health regulations have been captured by fringe crackpots who espouse views that the vast majority of the US public—and nearly 100% of health professionals—reject.

Musk has adjusted Grok’s algorithm so it’s now a neo-Nazi.

Pretty cool that almost every progressive commentator, elected official and organization still uses Musk’s X algorithm to communicate with the public! Good job guys.
