Yeah right, but we're so far away from creating even a single "upgrade" that's comparable with the human body. For example, even the best cameras would never even be in the same competing arena as the human eye. No sensors come close to our sense of touch.
The transhumanist ideology is nothing else but some kind of perverted ideology that we somehow would be upgraded with a usb port sticking out from the skin.
Even the very best tools we have today to save lives and help our bodies sucks in comparison with the biological counterpart. Sure there may be a future that we would "upgrade" ourselves, but when that time is here (which would be very, very far into the future) everyone will instantly do it because it will be so much better. There wouldn't be some kind of discussion about it since the result is so obvious.
For it to happen, whatever we replace something with will have to have all the features that we currently enjoy + a lot more.
