Well I asked this https://www.lesswrong.com/posts/X9Z9vdG7kEFTBkA6h/what-could-a-policy-banning-agi-look-like but roughly no one was interested—I had to learn about “born secret” https://en.wikipedia.org/wiki/Born_secret from Eric Weinstein in a youtube video.
FYI, while restricting compute manufacture is I would guess net helpful, it’s far from a solution. People can make plenty of conceptual progress given current levels of compute https://www.lesswrong.com/posts/sTDfraZab47KiRMmT/views-on-when-agi-comes-and-on-strategy-to-reduce . It’s not a way out, either. There are ways possibly-out. But approximately no one is interested in them.
This is not true for AGI.
