Jaron Lanier's book "You Are Not A Gadget: A Manifesto" is all the buzz on the web this week.

Lanier, one of the founding fathers of virtual reality, takes on what's become conventional wisdom about Web 2.0, Facebook, MySpace, YouTube, Wikipedia -- which all add up to what he calls hivemind.

Lanier spins out a dystopic future of a time when individuals upload everything they know to create what the "lords of the computing clouds" believe will be perfect knowledge.

According to Lanier, Web 2.0 rests on the ideology that the universe is made of computations and if we digitize our lives, we'll attain eternal life.
