The world gets both better and worse. it is something that I regularly get voted down for saying here, but IMO the west is unduly pessimist because it had a golden age from winning the cold war until the late 2000s, took an overly optimistic view of the future and the inevitability of progress (remember "the end of history") and cannot cope with things going back to normal. Things get better, sometimes they get worse…
I would argue that we worked our way to the post cold-war golden age, and then destroyed it with greed, which led to financial pain, which led to political nonsense, which led to the rubbish we are in right now.
So the period we are in right now is not the "back to normal" phase, but an actual decrease of human evolution. Not dissimilar to things that happened in the past, for example with the collapse of the roman empire.
