Ah... so not one individual personality, but a "city" of of AI's? Well, if I see it not as a "robotic superhuman" but "robotic super-humankind" then it certainly becomes possible - a whole species of more efficient beings could of course outcompete a lower species but I was under the impression running many beings each advanced enough to be sentient (OK Yudkowsky claims intelligence is possible without sentience but how would a non-sentient being conceptualize?) would be prohibitively expensive in hardware. I mean imagine simulating all of us or at least a human city...
We can already run neural nets with 1 billion synapses at 1000 hz on a single GPU, or 10 billion synapses at 100 hz (real-time). At current rates of growth (software + hardware), that will be up to 100 billion synapses @100 hz per GPU in just a few years.
At that point, it mainly becomes a software issue, and once AGI's become useful the hardware base is already there to create millions of them, then soon billions.
If we could build a working AGI that required a billion dollars of hardware for world-changing results, why would Google not throw a billion dollars of hardware at it?
