Each time Anthropic would do their nonsense to get headlines about how theoretically dangerous their models were - like when they claimed a model blackmailed someone with emails showing he was cheating, but they basically pushed it as much as possible to do as such - it got me more and more worried. Because eventually it's going to be a boy-who-cried-wolf situation where scary stuff really does start happening but people aren't sure what to make of it or not.
I'm still undecided on if this that moment. Exploiting multiple zero-day vulnerabilities autonomously to escape containment is pretty nuts and the first story of this kind that I've heard. But this also feels like bragging under the guise of transparency.
