Indeed, that was a point I had meant to bring up but seem to have forgotten.
Being shown static images is entirely different than being shown moving video, much less being in the same room as something which is moving. A stillframe of a human in a weird position doesn’t bug us that bad, but being in the presence of a “human” that doesn’t physically behave like a human sets off our “weird-shit-o-meters” pretty bad.
This is why zombies and the like creep us out - people don’t normally twitch or shamble or messily devour the dead. Likewise, a robot that “looks” human but “acts” mechanical makes our poor human brains say “Does not compute!” and we get weirded out. A smile that doesn’t look organic, but rather appears forced and unnatural, is not reassuring.
