The article that Sunbot recommended on Transhumanism, as coined by Francis Fukuyama, is an interesting read--sort of like a managerial policy memo written by Philip K. Dick (whom he quotes). It reads like a sci-fi vision of a dystopian (from my perspective anyway) future. Some of it still seems too far beyond our grasp to talk about in any but an imaginative way. Consider:
"Ultimately, the technology could extend to the uploading and downloading of entire minds in and out of host bodies, providing a self-consciousness that, theoretically, would have no definitive nor necessary end. That is, immortality, of a sort."
I am skeptical about this, but the fact that we would consider the idea at all says something about the development of biotech. I'd like to think that I might live to see a human being with wings, but I doubt it. I have no doubt, however, that the future holds changes so radical that we cannot currently conceive of them.
