It seems like right now "superhuman AI" is a buzzword that people like to use when they want to be covered by the press.
I'm surprised OpenAI didn't chime in. Physicists seem to use Aliens or multiple dimensions for this purpose (But some also use AI for the same effect).
It sort of distracts people from actually asking real questions like how to use AI / ML responsibly because the former doesn't require much to speculate about.
