There is more than one way to have a problem though: with awareness of it, or not. And then within that binary there is...what? A spectrum? So goes the saying. But what if that much better representation is just starting to climb the curve of competence/complexity?

Is it highly unlikely that humanity might some time in the next couple hundred years look back at us and shake their heads about how simplistic and naive we are, and I include the so-called "experts" in that. Is it impossible that there's something that no one sees? Or maybe even more complex than that?

Well, it's possible a species would not find such a thing, because it never thought to look for it. Perhaps too busy looking for other things, of questionable utility.
