The concept of the Uncanny Valley — a creepy feeling caused by artificial humans who are almost, but not quite, convincingly real — dates to at least 1970, decades before the dawn of modern computer animation. At this point, I wonder whether we’ll ever see digital people who aren’t immediately identifiable as animations, at least if they’re in situations meant to evoke emotion. (Some of the most impressive examples I’ve seen have been sports figures in video games, where it’s more about action than what’s going on in a character’s brain or on its face.)
