The latest seminar (Ken Dychtwald on "The Consequences of Human Life Extension") isn't up for download yet - and not having read much of him or his materials yet, I can't tell you whether he's on the side of light or darkness (or even really involved for that matter) in the anti-aging marketplace. Any of you folks who know more than I are welcome to educate me in this matter.
Last night, I went to the Long Now seminar with densaer. Ken Dychtwald on the consequences of human life extensions, and the like. Relatively short-term stuff, and relatively standard content, but he's a good speaker.
