The relevant parts of the USG are mostly run by Musk and Vance nowadays, who have already decided either that they've found the solution to alignment (curiosity, or whatever Musk is spouting nowadays), or that AI safety is about wokeness. They're not going to change their minds.

What's the basis for each part of these statements? I was curious for more elaboration on Musk in particular, since as far as I can tell he's demonstrated pro-AI regulation stances prior to 2025.
