The AI safety debate detonated this week when a researcher named Jacob Coxon, who spent roughly six weeks at Anthropic, posted a resignation thread on X claiming the people building frontier models "earnestly believe that it could kill us all by the end of the decade." The tweet drew approximately 150 million views — a reach Jason Calacanis compared to Elon Musk's "cocaine back in Coca-Cola" post.
To David Sacks, speaking on the All-In podcast, this was not a spontaneous act of whistleblowing. "There's nothing new here," he said. "This is the same doomer histrionics that we've been hearing from this crowd for a long time. The media is calling him whistleblower, but what evidence has he brought forward that we didn't have? This is all just vibes from him."
Sacks spent the night researching the amplification pattern. What he found, he argues, is evidence of an orchestrated campaign. The account had almost no followers or prior posts. The Wall Street Journal story appeared to be published minutes before the tweet storm, implying a pre-arranged embargo. Within 10 to 15 minutes, three well-funded doomer organizations — Encode AI, the AI Policy Network, and the AI Futures Project — all amplified the post with nearly identical messaging.
All three groups, Sacks notes, are funded by Jan Talen, a top effective-altruism mega-donor who co-led Anthropic's Series A alongside Dustin Moskowitz and Sam Bankman-Fried.
