For the US government to step in, they'd have to do something extremely dangerous (and refuse to share with the government). If we're talking about video generation, the benefits they have are financial, and the lack of accountability is in that they can do things no one else can. I'm not saying they'll be allowed to break the law, there's plenty of space between the two extremes. Though, given how things were going, I can also see OpenAI teaming up with the US government and receiving exclusive privileges to run certain technologies for the sake of "safety". It's what Altman has already been pushing for.
