Bioethicists, prosthetists and transhumanists focus on their collective "bionic" assumptions to bundle their fears and hopes. There is even a trend called Transhumanism [link].
But as we know by now, "bionic" hands do not deliver. Not really. You can wave them around, but even when attending a user workshop and discussing how to change a bike tire, the company product ambassador recommends taking the wheel to a shop. So, not really.
This shows the charmingly simple - but functionally enhancing - handling of a hot piece of meat and the hot frying pan using a prosthetic hook.
Absence of recognition of this act as clear proof of human enhancement also proves absence of rational thought in the beholders, to conclude this discussion.
I had already previously figured this part of the "enhancement debate" was mostly myth and fear driven. And we may then focus on how fear disables rational thought.
