If the people signing this document https://www.safe.ai/statement-on-ai-risk about "AI risk" were serious, they wouldn't keep building these systems and selling them (actually renting them out) on the open market.
The list is advertising and useful idiots.
Statement on AI Risk | CAIS

A statement jointly signed by a historic coalition of experts: “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”

@tante Like most, the signatory list is basically an archeological site. The deepest stratum is advertising, next come the useful idiots, followed by various migratory cultures, etc. It's mostly Americans, who've never been very sharp when it comes to sniffing out affirmative critiques.
