Yes, we're asuming different meanings for "hacker", and I was hoping for the one I take is the more accepted one for this site (Hacker News), those who are "trying to write interesting software, and for whom computers are just a medium of expression" (http://www.paulgraham.com/hp.html)
In any case, point taken as I probably got a bit carried away on my comment above, the talk referenced is more about the collaborative benefits new technologies bring to us.
Still, when I think "hacker" I think solitary, ego-driven programmer, doing immature things to prove himself. I think of the anger and non-compromise that comes out of some of the old beards.
If "hacker" has been reappropriated that's great. I don't mean to quibble over words--regardless of what we call things, I am very optimistic by the growing team-work and social awareness of internet communities.
