personally i agree with what macdorman states. i have personally come upon robots in japan and parts of the U.S. that seem to have diminished senses. wires that are showing and slow movement or speech does somewhat disturb me. i have ,however, learned to accept that our own technologies will be our end. humanity will end when robots feel that we have become obsolete and are no longer an asset to them. if u have ever seen a facility where robots make robots you will indeed understand what i am trying to say. in a few games i have seen characters "speak" yet thier lips to not move. some characters seem to slur certain aspects of speech as if they had a lisp or other speech impairment. overall i think that robots need to have distinct features that show what they are.
