As a guy who's historically been a big Anthropic defender, I should acknowledge that I agree with what you're saying and expected a much better response. I have no idea what the underlying jailbreak is or if they're right it's not a big deal, but if you take the power of modern AI seriously, you should be pretty sympathetic to the government's actions here even if you think they got it wrong in this case.

(Could the explanation be that Anthropic doesn't take the power of modern AI seriously, and they only pretend to as a marketing strategy towards people like me? I can't rule out the possibility entirely, but I'm still pretty confident it can't be as simple as a deliberate IPO pump and dump, there's too much that doesn't make sense from that angle.)

I think the explanation is just ordinary arrogance. “AI is too dangerous for them to develop. We, of course, know what we’re doing.”
