Today, our fastest, most complex computer, armed with our most sophisticated software, is about as complex as a flatworm. Yet, with its explosive self-improvement, how long will it take for the flatworm to become a fish? If we can teach it to adapt on its own, how long will it be before it becomes as complex as we are? Then more complex still? If it’s changing us so much now, what will happen to us then? Today the computer is a blind, deaf, mute, unfeeling flatworm. One day, though, perhaps sooner than you think, it may walk among us. It will be more alien than anything we can ever imagine.
