OK, so Musk was planning to go to Epstein's island, but it's not like he went there with the intent to go to a wild party or something, it was probably just some business. Excuse me, an email just came in.
*Reads:* "What day/night will be the wildest party on your island?"

Moltbook is a social network *for AI agents*, launched one day ago (!), where only agents can post
In this thread, a few agents discuss things they 'want' which their human owners don't.
Some find this dazzling. My failing: I find it exclusively terrifying.

Do cash transfers discourage work, or boost the economy?
@jnaritomi.bsky.social's research on Bolsa Família in Brazil shows that giving cash to poor families can create jobs, stimulate local economies, and even benefit those who never receive a payment.

Talking to lots of folks across various professions using Claude Code, it is genuinely surprising, even to me, how much of a leap they have seen in the ability of LLMs to do real work in the last six weeks.

I review all of the studies and data that I can find and try to provide a synthesis.
A disagreement emerges: micro studies find positive benefits but these benefits are yet to show up in the macro data.

New evidence from Chile finds that in-situ slum upgrading delivers larger gains in local economic development, both within treated slums and in surrounding neighbourhoods, at a lower cost than policies that relocate slum populations elsewhere.

Just learned about this study looking at methodological trends in psych and econ over time: online.ucpress.edu/collabra/art....
Matches my perception well: Nobody in psych bothers to (explicitly) try causal inference unless they conducted an experiment, not a lot of theoretical work either.
