If we are constantly working towards a solution to something, what happens when we solve everything?

Imagine a world with no poverty. No death. No corruption. No pollution. No racism, sexism, or ageism. No scientific problems left to solve (we’ve answered everything). No social strifes. No sadness. By this point, humanity has absolutely nothing left to solve. All the bad in the world has been eliminated.

Let’s forget the impossibility of this, and let’s just say that it happened. What happens to humanity’s natural curiosity?
