Some people, like Stephen Wolfram, are eccentric geniuses... while some like David Levy are just plain brilliant. I just read the Wolfram article (REALLY LONG) and am thoroughly impressed by the guy. He may/may-not be the next Asimov or Sagan, but his ideas are certainly revolutionary. Sometimes I wonder if I want to be like Wolfram, a thinker who redefines existence as we know it, or like Levy, who makes life just a bit more easier by being just a little more innovate to push the technology just a bit further. I hope the latter.
