$HELL? Is that SHELL with a $? Is that Shell Oil and Gas? Is Shell Oil a problem for the human race? I suppose it could be, but your point escapes me.
Or maybe the $ is a typo and you mean the Christian notion of Hell? Is Hell a problem for the human race? Not likely as, even if it exists, it's only a problem in the after life. So again, your point escapes me.
We all ready have a well defined rigorous AGI[0] that would have god like intelligence. There are some approximations that played pacman [1] without knowing anything specific about pacman itself. i.e. it learned how to play by itself.
AIXI is an artificial 'general' intelligence. It is not hard coded to do a specific task. That neural network is useless at doing anything other than playing tic tac toe
If by "null hypothesis", you mean artificial intelligence that exceeds human intelligence is impossible, that is a bold claim. Since human intelligence is nothing more than a successful evolutionary algorithm implemented in 3-dimensional cellular networks, it is inevitable that we'll be able to copy and improve the algorithm at some point in the future. Then we'll have artificial intelligence that exceeds human intelligence. Then what?
