A Steward is somebody who wants to manage the world as a precious resource, and an Extropian is someone who wants to let some big, impartial evolution-like process run wild with it. Extropians differ about which process this should be, though it certainly can be the more traditional libertarian capitalism combined with the self-propelled onslaught of new technologies. Extropians don't worry about natural resources running out, or about poverty, or any of the other problems that frighten Stewards, because they are convinced that new technologies will solve the problems if we just give capitalism and science an unfettered chance. Stewards speak a language of what's already here, like human beings and rocks, while Extropians believe that everything here is going to be replaced by new, evolving things anyway. Extropianism is in my dreams because it is creative and unbounded, and yet it gives me the creeps.
Evolution is nothing more than the victor's word for genocide.
Every little detail about you, like the curve of your nose, reflects the countless horrible deaths of your potential ancestors who didn't survive. The great mercy of civilization is that it ended evolution. I don't want to bring it back. On the other hand, I worry that Stewards will want to manage and control precious things that only exist in their mysteriousness, such as sensuality, music, and the emerging wilds of the Internet. We should attempt to regulate and control the hell out of everybody involved.
