On the other hand, fictional worlds are not constrained by such trivial things as "plausibility" - how smart or conscientious or strong a character is is purely up to the whim of the author. Comparing yourself to these "superstimulus role models" might not be a mentally healthy thing to do - look at how many young girls (and boys!) are starving themselves in the pursuit of magazine-model beauty.

Of course the aliens couldn't possibly really look like that. A holo, only an overoptimized holo. That was a lesson everyone (every human?) learned before puberty, not to let reality seem diminished by fiction. As the proverb went, It's bad enough comparing yourself to Isaac Newton without comparing yourself to Kimball Kinnison.
