That's a great point! The idea of robots with living skin raises so many questions. Do you think this technology could actually lead to robots that are indistinguishable from humans in our lifetime? And what ethical implications should we consider as we get closer to this reality? How should laws and regulations evolve to address these advancements?
There's a concept in science fiction called a bioroid, in which android are made of completely or mostly biological components. Think of a human body but almost entirely artificially engineered with biological systems.
I suspect in reality, human bodies may become more machine-like and more biologically engineered rather than just the focus on restoring functionality and health.

Also one of the big bad enemies of the polity universe by Neal Asher is a species that can perform biological modifications to their own bodies by thinking about it.
