Yes, an AI making massive gains in bug finding is hugely important and good, it may even lead to a net neutral with the amount of bugs introduced by other AI coding processes, but it’s a far cry from how mythos is portrayed most of the time: a automatic super hacker.
But I think that's a problem with the people portraying it that way, not with Anthropic's messaging. If you've invented "just" a massively more powerful bug finder, it still seems right that you ought to let banks and critical infrastructure providers run it on their systems before it gets in the hands of people who might want to hack them.
