It's in our nature to worry about the state of things after our death. If you have children and grandchildren, it's entirely fair to worry about their well-being long after you will be gone. Same is true even if you don't have kids but have at least worked hard to leave behind something for future generations. (Many of us aren't concerned enough about such things.) If none of that applies to you, perhaps you empathize with humanity as a whole, in which case you'd do well to bury your anxiety by focusing instead on the good you can do for people here and now.

But I am disappointed that if we screw up badly enough, any subsequent species rising to our level probably won't have the time or resources left to go on and surpass us.
