I'll leave you to the full article (link is below), but here are a couple of excerpts to give the flavor of the Transhumanist concept:
"As the name implies, Transhumanists are people who want us to become "beyond human". It’s an umbrella term for a broad family of ideas united by the vision that technology now, or at least soon will, allow us to greatly enhance human intellectual, physical, and psychological capacities. That means everything from bionic limbs to uploading our entire brains on to memory sticks and carrying them around with us as back-up."
Well, while there are times I'd like to have my, uh--what's the word? Ah, memories!-- on a stick, the reality is I'd probably forget where I put it.
Here's another excerpt, this looking at some of the down-sides:
"The whole project throws up very difficult ethical and philosophical challenges. Is an uploaded mind still human? Should we give "human rights" to an artificial intelligence with a superior intellect to a human? Then there’s the bread-and-butter social problems. Presumably, human enhancement technologies would be disproportionately available to those with greater financial resources, creating a genetic divide. And if you lived forever, are you taking up the place of another generation? What about the more mundane things: what would be a fair prison sentence for murder if we could all live for 200 years? Or the right retirement age. I’m guessing it won’t be 70 if we can all make thirty score and ten. Above all: are we happy about all of this, and can we stop it?"
