I also wonder how much longer it will be before we go in the android direction? We are in a way with the artificial limbs and such. But what if brain implants would be of a benefit? Would people want to do that?
Yes. That's the aim of transhumanism; to incorporate new technologies into the human body. Although it's widely regarded as a scary idea
and often involved in fictional dystopias, it need not necessary be disastrous. Instead of the borg or the cybermen, think of Julian Bashir or Iron Man. There was a Ted talk about this, I forget which one, but the speaker made the point that human augmentation started the first time a human wrote a symbol on a chunk of rock. Essentially, writing extends human memory - something can be remembered without a single living person remembering it.
At its base, the goal of transhumanism is to overcome human limitations - to make humanity more capable and less weak and vulnerable. Imagine a new breed of humanity capable of exploring the cosmos rather than simply watching probes on TV. Human technology is advancing at an incredible rate - the human body, not so much. Increasingly, it's becoming the weakest link. A lot of human failings - dementia, irrationality, violence, fanaticism - among others, are ultimately rooted in biology. Augmentation could eliminate or minimize bad traits while preserving good traits. And rather than be disastrous, it could be a way forward.
