There've been so many advances in medical technology, to such a degree that genetic cloning/modification has preceded robotic construction.
We're seeing the advance of nano-bots (yes they exist, no not like The Borg in Star Trek).
What if Robots will exist.... what's more... what if they have emotions.
By the time Robots come about we will have synthetic "plastic" bio-computers.
It is conceivable that humans and robots could be biologically compatible. We're already talking about robotically controlled biological-computer hearts.
What do you think will happen? Are these creatures still considered robots? Or will they be so close to human they might as well be like Bladerunner Replicants?
I sense a very strong Tezuka connection in this discussion, so I put it here instead of the offtopic forum. Somehow I can forsee an Astro Boy example involved.
