Computing strength bypassing the human brain is debatable.
The Human brain performs many calculations in the subconscious. Autistic people have a level of their subconscious unlocked but it fucks their conscious abilities.
Either way, it might be more powerful, but unless a complete AI program can be written that learns and re-programs itself to take advantage of its superior understanding of it's own program - the perpetually infinite possibility of analysis and improvement of it's own programming is scary and 'Judgement Day' like.
However, if the human brain isn't capable of programming something with superior intellect then it goes to waste because it is limited to the programming abilities of the human mind that is creating the software.
This is the current drawback of a computer system - plus there is currently no self powering ability (like with organic objects).
Yep this stuff is very complicated.
