I've had a lot of the same thoughts, although in a much simpler form. So, of course, I think the talk is brilliant. Thanks for posting it.

I found it especially relevant how he illustrated thinking in terms of imprinting and erosion. I've been thinking about my personality, and how I think about things, in different, but oddly similar terms.

I also agree that personal computing is, to a large extent, re-inventing the past. The best quote I heard on that, as best I can recall, is "The PC recapitulates the mainframe", which is borrowed from Biology's "Ontogeny Recapitulates Phylogeny".

I love the content of that presentation as well as the fact that the presenter was clearly as high as a kite.

Why do you say that? The content or the style?
