I agree for other reasons as well. I remain unconvinced of the the notion that individual neurons can be reduced to the functionality of a simple on/off transistor. Neurons themselves have vasty complex metabolic and neurotransmitter pathways. The other mistake I see computationalist making is the realiance of the Turning Test as evidence that they have acheived human-level intelligence. As a friend of mine who's writing his Doctoral Thesis on beleivable agents says, 'The gap between believability and actuality is much wider than most working in the field want to admit'.
We are already on the threshold of achieving the necessary 10 teraflops that Hans Moravec insists will yield human-level intelligence. His calculation are based on the transistor = neuron formula.
I'll wager anyone right now that even the first 100 teraflop supercomputer will not pass the Turing test let alone be capable of humanlike computation. And besides, as some wiseguy once said, "It's the software stupid!".
