Recently, major AI industry players (incl. a16z, Meta, & OpenAI’s Greg Brockman) announced >$100M in spending on pro-AI super PACs. This is an attempt to copy a wildly successful strategy from the crypto industry, to intimidate politicians away from pursuing AI regulations.🧵

Across reporting and opinion pages, the NYTimes coverage on the impact of the tragic dismantling of USAID has been impressive IMO. While there's surely room for some productive reform, USAID represents some of the US gov's most effective spending. Thousands will needlessly die.

“We are well past euphemism about ‘pushing the limits,’ ‘stretching the envelope’ and the like,” said Peter M. Shane, who is a legal scholar in residence at NYU... The array of legal constraints Mr. Trump has violated, Mr. Shane added, amounts to “programmatic sabotage and rampant lawlessness.”

On Friday morning, the staffers at a half dozen U.S.-funded medical facilities in Sudan who care for severely malnourished children had a choice to make: Defy President Donald Trump’s order to immediately stop their operations or let up to 100 babies and toddlers die.

They chose the children.

In spite of the order, they will keep their facilities open for as long as they can, according to three people with direct knowledge of the situation. The people requested anonymity for fear that the administration might target their group for reprisals. Trump’s order also meant they would stop receiving new, previously approved funds to cover salaries, IV bags and other supplies. They said it’s a matter of days, not weeks, before they run out.

More people who take a sociotechnical approach to AI (many of whom think it is fake and sucks) need to condition on the fact that real advances have been made, and more are to come. Not just to avoid irrelevance, but because the sociotechnical approach is so urgently needed for what’s coming.

OpenAI knows how to boil frogs. Crossing this threshold into the battlefield under the cover of drone defence enables the eventual transition to lethal force against humans. That is where the money is; that is where they will go. Their military pivot is not complete - it's only just getting started.
