predicatability (programmed), vs. spontaneity.
@XanderHenderson What about computer generated art? Any thoughts? Again, I think it can be a form of art, but different from free-form human paining, drawing, etc. But probably no less an art. And photography is probably even more complicated a subject!
@Xander One arena: humor/stand-up comedy, is one area in which I can not yet envision computer generated humor. I'm not talking about memes drawn on-line, or anything like that. I can't imagine anything comparable to Drew Carey, or Seinfeld, Ellen D, or any number of a host of comedians, that a computerized voice could be programmed to create. Maybe humor is the ultimate human quality upon which to test future technology.
