Within a century, it will be possible to scan a human mind and reproduce it inside a machine. Regardless of whether our minds are just very sophisticated analog computers, or whether they have a quantum-mechanical element (as Roger Penrose proposes), we will nonetheless be able to duplicate them artificially.

Already, at the close of the second millennium, a transhumanist movement has begun; Christopher Dewdney is the principal Canadian spokesperson for it. This movement holds that uploading our consciousness into machines is desirable, since that will free us from biological aging and death. On the other hand (a decidedly biological metaphor), there is more to being human than just the networks of synapses in our brains; clearly, much of what we are is tied in intimately with our bodies. We may find that uploaded humans are not happy — indeed, are incapable of happiness or any emotion.

Just as laws today are moving toward recognizing a woman's right to control her body and any separate sentience that may be contained within it, so too will the laws of the future recognize the right of humans to upload their consciousness and then dispose of the original biological versions of themselves; such eliminations will not be seen as suicides or murders, but rather as a natural, perfectly legal step, eliminating a no-longer-needed biological container and preserving the uniqueness of the individual.

It may, in fact, be dangerous to build conscious machines that are more intelligent than we are; just as intelligence may be an emergent property of sufficiently complex systems, so too may ambition and desire be emergent properties of sufficiently intelligent systems.

Although we used to consider the mastery of chess to be the pinnacle of human intellectual achievement, we've had to concede that it is simply a mathematical problem, and even today's primitive computers can do it better than the most skilled human. But there are other realms — including art, philosophy, and scientific theorizing — that, because of their intuitive, nonlinear nature, we may always be better at than any machine. Our AI servants may free humanity at the dawn of the fourth millennium to concentrate on these areas.
