I think that the first 20 to 30 years will be very difficult for humanity. There is a distinct reactionionary movement that is blocking or even reversing progress needed to fix various problems (including, but not limited to climate change, destruction of ecosystems, housing problems and the world population aging beyond sustainablitiy). It will get very messy.
After the boomer generation has died out as well as my own (GenX-er here), humanity can hopefully look forward again. As I age, I really think that it is our two generations that are blocking progress. As millennials and Gen Z ages, they will hopefully learn from us how not to do things.
