A lesson from gamedev is that players will deliberately restrict themselves - sometimes to make the game more fun or challenging, sometimes to appeal to their aesthetic principles.
If/when superhuman AI is achieved, those limitations will all go away. An owner will just give it money and control and tell it to optimize for more money or political power or whatever he wants.
That's a much scarier future than a paperclip maximizer because it's much closer and it doesn't require complete takeover first, it'll be just business as usual, except more somehow more sociopathic.
