It isn't mere intelligence that we seek but _human_ intelligence. NN research will more likely than not culminate in something akin to, say, dog or horse intelligence or features of intelligence share by all species, rather than the (desired) human intelligence.

I see nothing in NN research that is quintessentially human (although there may be circuitry that is unique to humans that has not yet been revealed, this will most likely be uncovered by brain science rather than NN research IMO) and so I believe NNs are not the right level of approach to AI.
