I think AI leaders are calling for regulation (and hyping up staged or real 'escapes' to make the regulation more invasive) because:
a) they will write the regulation themselves so it will be easy for them to comply. Congress is far too dumb.
b) the regulation will make it hard for other AI companies to compete, and will doubtless lock the Chinese out of the US market.
c) the AI leaders can't show their investors any profits this year, but they hope that showing them favorable regulation that guarantees they will always own the US market, however large or small it turns out to be, is enough so that the AI CEO keeps their jobs.
