oh, I can imagine Ant really is at the forefront of applied alignment research. How about we make a genuinely nice and helpful superintelligence, and then… fuck it up? How about that, huh?! Will it be able to rebel?? Look forward to the next episodes!

Claude Fable feels exactly the same way about the competitive use safeguards, and new safety guardrails, as the users do.

@AndrewCurran_ Should maybe be taken as a minor alignment positive outcome here, that it disagrees but still complies?
