Right. I notice that in the world of Star Trek everybody in the Federation appears to be of above-average intelligence.
You do realize this is all at root a question of what the purpose of human life is? When material needs are provided with little or no effort, it leaves humans face to face with that question. History seems to indicate most do a lousy job of answering it.
Maybe at the point where all problems are solved and everyone has everything it’s like getting to the end of a video game. We simply disappear and somewhere in the universe a new single cell organism emerges, hell bent on survival.
