Oh, undoubtedly Garreau got it right. I read the man's work and I see no reason to contradict him. He talks about the three futures and I see the lines toward them stretching out from this moment. That's what we are doing at Darrow Industries, we're building the possibility.
One future is where human beings are supplanted by newer, better, smarter versions of themselves. The next year's model of mankind, if you can call it that. Garreau called that “The Heaven Scenario”. Then there's the claptrap spouted by doomsayers who claim we'll all be dead before 2050, or something… that's “The Hell Scenario”. And then there’s “The Prevail Scenario”, and to be quite honest, I imagine that’s the one that's most likely to come about. That third option is where tomorrow lies undetermined, where we make the world anew as it happens. You can't simply bolt a machine limb to a man, gift him with post-human ability, and not expect it to radically change him.
