Hmmm...
Well, Pythagoras came up with a^2+b^2=c^2 about 2500 years ago, and I imagine the average Greek couldn't possibly have cared less about it. But much of what makes our world what it is today is based on that discovery or what followed from it.
But you said earlier that you don't care much about things that happen 100 years from now, so I don't see that line of reasoning being terribly impactful. But 100 years is the blink of an eye in the scope of history, and if that's too long of a period for us to care about, I wonder where things are headed for us in the long term.
People will bounce of the walls in rage if you say a critical world about one of their kids, but many of these same people don't seem to be concerned if there is a world at all for their great-great-great-grandkids.
Anyway, not necessarily grouping you in with anyone in particular.
