I agree that all designed systems have limitations, but I also suggest that all evolved systems have limitations.
This is just the "no free lunch theorem" -- in order to perform better than random search at certain optimization tasks, a system needs to have some biases built in, and these biases will cause it to work WORSE than random search on some other optimization tasks. No AGI based on finite resources will ever be **truly** general, be it an engineered or evolved systems Evolved systems are far from being beyond running into dead ends ... their adaptability is far from infinite ... the evolutionary process itself may be endlessly creative, but in that sense so may be the self-modifying process of an engineered AGI ... -- Ben G On Mon, Jun 30, 2008 at 3:17 AM, Terren Suydam <[EMAIL PROTECTED]> wrote: > > --- On Mon, 6/30/08, Ben Goertzel <[EMAIL PROTECTED]> wrote: >> but I don't agree that predicting **which** AGI designs can lead >> to the emergent properties corresponding to general intelligence, >> is pragmatically impossible to do in an analytical and rational way ... > > OK, I grant you that you may be able to do that.
