Thought uses experiential metaphors from basic physical interactions with the world such as light/dark, up/down, etc. That certainly seems part of it. I've read Lakoff, and second your recommendation to anyone interested in this stuff. I'd also recommend Pinker's "Stuff of Thought" (http://www.amazon.com/dp/0143114247/ http://www.amazon.com/dp/0143114247/) for this topic. AI will never come from digital machines If you consider AI as limited to human cognition, sure. I don't think it's anyone's goal to clone human cognition, however - humans are full of biases, survival instincts, tribal intuitions, etc. Then I think we can agree that a subset of human cognition could also be very interesting, and I imagine the subset of cognition which can be "hoisted" without an embodied mind is quite significant. For example, I think we can achieve the level of cognition of congenial deafblindness (those born without vision and hearing), which is pretty extensive.
