I posted this on his site but it needed to be approved. Also, there's actually a comment in the book (I just borrowed my gf's copy) in which they speculate that multilayer networks could be built, but since they only computers they had were .15 MIPS KA-10s (and all the figures in the book were hand drawn) they didn't pursue it.

My guess is it's still early days on the AI boom.

My comment on AI Winter:

Minor correction: Marvin and Seymour's Perceptrons book was published around 1969 and nuked neural nets around there. AI winter set in in the 80s as expert systems and similar crude symbolic systems proved not to be scalable (I was at that AAAI in 1984 and remember that panel well).

Moore's law rescued NNs and is about to rescue symbolic AI as well.
