Are we deceived by computer generated beauty?

[Human No More]

That's not being deceived - that's just optimisation. It's taking features that are appreciated and creating a new combination - much like happens to any human via a random element; simply removing the random element from the picture.

You seem to be implying Neytiri is NOT attractive, in a disparaging tone - that to me seems like a clear agenda right there - well, yes, Neytiri IS attractive, and more so than many humans. Remember that ~50% of everyone is below average in any given respect. If I didn't know better, I'd think this thread was a concern troll.

Humans vary. Unless you're implying all humans are equal and ideal, then it is blindingly obvious to even someone stupid that some people (or depictions) are better than others. There is no reason that does not extend to depictions in general, as it has done for hundreds of years. The whole 'uncanny valley' idea is complete rubbish, it is arguable up to a point but then becomes terminally flawed.
