I have to disagree with your disagreement. Provably optimal computational substrates and representation can be optimized by co-evolution. This process is open-ended. > *.

As flexible as the human mind Stochastical optimization doesn't have any blinkers.

Self-modifying at If intelligence is infoprocessing capability, then any process that maximizes the ops/g and ops/J will also optimize for intelligence. > the meta-level is often dangerous, and it should be used only when the > same effect cannot be produced in the object-level.

Yes, it took evolution a while before it learned to evolve.

The whole language metaphor in AI is a crock. It makes so many smart people go chasing wild geese up blind alleys. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=303
