"If you mean it, let a committee investigate" seems more appropriate to me.

I mean I get that they don’t want to share details on how AI might destroy humanity but this secrecy also leads to speculation that this is just a PR campaign pushing for regulation, which might come handy.

You don’t need to tell the world what your super AI has given you to cause this panic but definitely you could share it with a group of experts who then inform the public in a report, couldn’t you?
