face-detection is fundamentally important to interpersonal interaction in the baseline human experience (are you aware of the phenomenon of pareidolia?)—fuck with it at your own peril, both for children learning how to read expressions by observing adults, but also, for adults interacting with virtual "AI" simulacra, instead of real human faces! ignoring these basic observations is naïve as hell, regardless of Thanksgiving dinner conversation palatability (always a high watermark for intellectual discourse)!

thankfully, I don't see any reason to believe this will take off "iPhone-style".
