OK, for those of you tired of all the political discourse of late, here's two really smart guys, Eliezer Yudkowsky (Singularity Institute, Overcoming Bias) and Jaron Lanier (Berkeley, Microsoft) discussing metaphysics and intelligence.
I've followed Lanier for years, attracted by his technological futurism ideas, his art and his conception of consciousness. I have also been interested in Ray Kurzweil's theory of singularity, which suggests that around 2045 human and machine intelligence will converge. Lanier attacks this, and Dennet's atheism, as useless ideology.
Here's Lanier on UCtv discussing Culture and Technology.
