I think this misunderstanding of MAD undermines his entire point. If everyone had equal access to nuclear weapons, our society would cease to exist rather quickly. It only takes a few bad actors to cause enormous harm.
I think he’s also naive to think that if open ai and anthropic were to stop development tomorrow then the problem is solved. As if there’s no one else that can and will quickly take their place. The real problem, which Dario is pointing out, is one of coordination. Everyone needs to agree to stop. That is the challenge.
