It's the idea of a machine having feelings and emotions (never mind the very real possibility of it thinking for itself, albeit in a rudimentary fashion) that bothers me. It hasn't been done, to the best of my knowledge. But everyone is focused on having robots that can "think", or look like they could be human, or at least seem human enough.
It's depressing, really, but until they accomplish this, I'm starting to think that I'll always think this way. Now, when I watch Astro Boy on Youtube, I sometimes think along the lines of "Aw, cute, but it'll never happen" or "They don't actually feel anything, so kind gestures are useless". It's pretty bad that it affects my thinking even within the series' canon.
