@johnzajac why not just change humans?

I think that's the sort of question that has been asked out of hubris throughout history and generally doesn't work out very well when it's tried.

Why not build power plants with perpetual motion machines to turn the gears? Well, turns out it just doesn't work, that's the harsh reality.

We are stuck with humans that like to like things, that will pursue the things that make them happy. That's just reality, for better or worse, and we really have to work with that, we can't fix them to make them different, to make them conform to our ideas of how they should be.

Even if that would make us happy, even if we would like to pursue that because that is the thing that makes us happy, which,... you see what I'm going for here.
