Dario's been beating the regulatory capture drum for several years at various intervals, always in the name of safety, but it's hard to not see how self-serving it is.
I'm personally very tired of reading the linear-algebra-median of every AI safety essay from lesswrong with the inserted opinion of "therefore all my competitors, especially those pesky open source ones from scary countries should be illegal, only I can be trusted to not abuse the computer god that I definitely will have in just a couple more releases and with a couple more trillion invested"
So, basically, make open-weight models illegal. It's nice for Dario to come out and say this so explicitly.
