Then again depriving a human infant of a face and hands could stunt its IQ.
For a sample of Rod Brooks views on this try:
AI (like bio intelligence) works by combining top-down (Minsky-theorized)
protocols with bottom-up techniques such as Murray Gell-Mann's "Plectics" and
Stuart Kauffman's "order for free" and Christopher Langton's "dynamical
patterns" along with the complex adaptive systems ideas coming out of the Sante
Fe Institute and Los Alamos.

I'd go so far as to agree with them, especially after perusing some of the

A new (well, really not so new) approach is to provide AIs with the challenge.
It does no good if researchers solve all the problems for AIs, because then the
AIs are just parrots (like some over-educated people). The real challenge is
designing AIs that can pick up the challenge of learning and thinking on their
own, for themselves.

I disagree. I find the new direction and emphasis of robotics the most promising
development since AI was first considered a feasible enterprise.

See if you can figure out how the sand mouse works.
Then we'll talk.
