I agree with Paula that we have peaked.
As i don't think it is possible to de-evolve, i do think we are heading backwards in mentality, i won't get into too much depth with it but simple things like male/female are now dire mainstream topics instead of technological inovations, we are still a society of by-standers and watchers, long since have we been the do'ers.
Sadly i believe the wiriting is on the wall for out future, with the current president recently signing a supply deal with Ukraine we inch so much closer to nuclear war. These are things we should have learned from our past, but sadly we did not, instead the world is full of brain dead TV drones who cannot think for them selfs anymore and only spew what they are told to, and in that fact i do believe we have de-evolved.
But alas all civilizations must come to a end and we are at ours.
