Ben,

A further thought occurs to me about how learning derives from practice - & I wonder whether you've thought about this. Basically, in humans and animals, the kinds of learning we've been talking about - learning to crawl, manipulate, walk, talk, play tennis forehands or pianos - involve not just practice but development. The body and brain have not only to discover appropriate trajectories of movement, (and associations of ideas), but they have to wire themselves anew, and grow muscles in order to support those trajectories and associations.The body and brain have to develop/evolve. And this is considerably more complex than a computer making new memory connections.

(My impression is that development is usually left out of scientific approaches to learning - it's so complicated).

But if organisms learn in this machine-morphing way, then there must be considerable advantages to it - & it may even be necessary for AGI. Have you thought about this area?

Ben:It seems to take tots a damn lot of trials to learn basic skills, and we have plenty of inductive bias in our evolutionary wiring...
