> The penultimate premise is if we create an artificial intelligence, whether it's an emulated human brain or a de novo piece of software, it will operate at time scales that are characteristic of electronic hardware (microseconds) rather than human brains (hours).

I never understood that argument, why would that be true? If I train a state of the art convnet it takes days on the most efficient hardware I can efford, why on earth would we go from nothing to superintelligent that also runs incredibly fast. Isn't it way more logical to assume that it will be slow at first?
