I feel like humans are so changeable, though. I wonder how the spectrum plays into this. For instance, are a person's facial demeanor changing based on their proclivities at the time? I'd be interested to know more.
I have known people who've been exclusively oriented one way for a long time and then they have changed at another point. and I'd love to know if this is something that AI would be able to pick up accurately in two different images of the same person at different times when they were expressing the other orientation.
There is always possibility of error in AI algorithms because after they are written by humans. I agree with you that humans have very diverse personalities and it cannot be mapped to code entirely
