Oh, I thought extropy was the opposite of entrophy...
Anyhow, this sounds like my cup of tea. I've done a lot of thought on the subject and decided that one way or another I'm going to try and replace my biological body with a mechanical one, which would not only be cool but would allow me to live much longer. I could also hook up to a computer and basically live in a Matrix-like world where the brain interfaces with the computer and all the senses are simulated and whatnot.
I pretty much think that's the future and we should get there ASAP with more research in things like robotics, mind-machine interface and nuclear fusion.
