Humans, unlike most animals on Earth, are in a position to radically change their own bodies and minds.
Some of the first concepts of cyborgs (including the 1960 paper that coined the term) imagined them as humans enhanced for space travel.
Nowadays we still don't have the advanced cyborgs that have been imagined in the past (yet), but we do have a lot of people with implants and/or prosthetics for medical and cosmetic purposes.
Is anybody looking forward to having more implants?
How about information-based implants that connect to your brain?
How about prosthetics that you don't _need_, but you _want_ for the extra capabilities they would give you?
