Ask someone from 100 years ago if they'd rather live with the threat of polio or put up with our problems.
If we had just been 20 years faster in some developments, some people very dear to me would still be alive.
If only you got to X in time, then Y wouldn't've happened. Or if you got there just a bit earlier, or later, you might have caught Y - or missed Y.
The people of 100 years ago had problems we don't. But we also have problems that they don't - and our solutions to the problems of today, some of them will create problems for the people of 100 years from now. We'll make mistakes, problems will arise out of what we do that we can't predict, things will come up that we can't foresee. Bad things happen and you can't solve for every bad thing in the world until there are no more. There will always be more.
And that's life. It's how it works. Different centuries, same humanity. Different cars, same train. People die of all sorts of things before their time and they always will. Different times, same pains. No amount of scientific and technological advancement will change that.
And that's what art and literature are all about.
