Here's the website. Humanity+ @ CalTech is hosted by the California Institute of Technology and ab|inventio, the invention factory behind QLess, Whozat, SocialDiligence and MyNew.TV.
The speakers list is a mix of the usual suspects and some new names. The usual suspects include Randal Koene, Suzanne Gildert, Michael Vassar, Max More, Nastasha Vita-More, Bryan Bishop, Patri Friedman, Ben Goertzel, and Gregory Benford. If you were following my tweets from this weekend you'll recall that Benford announced StemCell100(tm) at the Life Extension Conference in Burlingame, which is a product of LifeCode, a spinoff company of Genescient.
The conference is partially being organized by my friend Tom McCabe, who was recently voted on to the Board of Directors of Humanity+. Please let Tom know (his email is at his website) if you want to help sponsor the event!
