1) As I've argued, neither OpenAI nor Anthropic actually tried to isolate their computer-attacking tools under test from other people's computers.
2) What's also needed -as people like Nvidia CEO Jensen Huang and former FTC chair Lisa Khan are calling for- is for the major LLM manufacturers to be investigated and punished for the crimes they've committed. Given that they claim to be working on WMDs that they don't really know how to control, [0] and claim to be incapable of actually stopping work on those WMDs, their work should be halted while the investigation and trials are under way. I'd say that waiting five or ten years to pick the project back up is an inconsequential price to pay if it prevents the elimination of all of humanity.
[0] It's fair to call anything with 10% chance of wiping out all humanity a WMD. I expect that these claims are fearmongering, rather than being true and accurate, but why take the chance, amirite?
