My opinion is that Jane is correct. A robot will never be in the same sentient category as a human. AI, and nothing more than AI.
How do you form this opinion, like what's it based on? For example, IBM's Watson is an insanely intelligent (yet still imperfect) AI. There's so many chess playing AI's that are better than humans it's not even worth listing them. There are robotic limbs, as keith points out, that react to the electric stimuli produced by the brain and act as our own bodies. Robotic eyes make judgement all the time. Define the sentient category in which a human is contained and a theoretically super-advanced AI could NOT be contained. I'm not disagreeing with you necessarily, I'd just like to hear you flesh this out more.
