Yuri Milner's Global Brain
Yuri Milner has made much of his fortune by investing in Internet companies such as Facebook, Zynga and Groupon. These have been wise investments, but for Milner they're more than just financial ventures. They're the embryonic beginnings of the development of a global brain.
A global brain? It sounds very much like something out of "The Matrix." Milner believes an inevitable consequence of the Internet age is that all of the knowledge exchanged by humanity and machines will eventually coalesce into a supreme artificial superintelligence — a global brain.
Whether this global intelligence will be benevolent remains to be seen. We're guessing, probably not.
