I'm pretty sure that people of the future will consider the time between 1950-2050 century to be the golden age of our current Civilization.
There are so many basically unsolvable issues on the horizon that I see absolutely no chance that our society will survive in it's current form.
My bet would be that we'll devolve into another form of aristocracy as soon as AI/automation make a human workforce mostly redundant.
Technological progress is likely going to stagnate entirely at that point, we all know how rich people generally behave without outside forces...
