Protesters march on Anthropic headquarters and demand to be taken seriously

What's going on here?

The anti-clanker movement just had its biggest day in history.

Today, hundreds of protesters marched through San Francisco under the banner “Stop the AI Race.” The route was a frontier-lab world tour: starting at OpenAI's HQ, pausing at Anthropic's offices, and finishing at Google DeepMind.

The vibe on the ground:

• A live brass band, free slushies, and a guy in a Barney costume as “extinction commentary.”
• Signs like “stop slop” and “Pls Do Not Kill Me,” plus NSFW chants aimed at Sam Altman and Dario Amodei.
• Organizer Michaël Trazzi, a former AI researcher who once spent weeks on hunger strike outside DeepMind's London office.

It's hard to be taken seriously with a purple dinosaur on your front lines, but the demands were smarter than “ban AI.”

The ask was for every major lab CEO to publicly commit to pausing new frontier-model training, but only if every other lab on Earth verifiably pauses too. Current models stay online, researchers shift to safety work, and chip tracking plus compute caps keep everyone honest.

OpenAI, Anthropic, and Google all declined to comment.

What does this mean?

The AI resistance is growing.

Early gatherings drew dozens of people. Then two hundred people marched in March. Today, it was hundreds of people. And the gripes have spread from “robots might end humanity” to AI taking jobs, tech money inflating rents, and data centers draining power grids.

The awkward part is that the AI labs themselves keep making the protesters' case for them. Anthropic quietly scrubbed pause language from its safety rulebook in February, then said it “would” slow down if rivals verifiably did too. Ask DeepMind boss Demis Hassabis about a collective pause and you get “I think so.”

CEOs are onboard in principle. They just won't put it in ink.

Why should I care?

1) Barney takes Ws.

Local groups have already blocked or delayed more than 75 US data center projects worth roughly $130 billion in Q1 alone. That's the biggest quarter on record. And the pressure is turning into law. Lawmakers introduced over 300 data center bills in statehouses in the first six weeks of the year (mostly over power bills, water, and noise).

2) The pausing is ragebait.

No lab is stopping. The genie is out of the bottle and there's no putting it back. But Michaël Trazzi knows that. The demands are built to be loud and controversial so voters start noticing and caring. Because that's the only way Congress will write new AI rules into law.
