My best guess atm is that the U.S. has a good 10 to 20 years left. Good in terms of the economy.
Increased surveillance, cancel culture, capital controls, taxation, polarization, etc., as well as obesity, and less and less people able to do TGUs with the 48kg kettlebell. After the 10 - 20 years, U.S. will become a bit like the U.K. is today. East Asia will then reign a bit. Russia's a bit unpredictable - it's got the right amount of corruption, but it's a bit ossified and King Vlad cannot live forever, despite all the stem cells he's receiving. When he leaves Metaverse Earth, there may be a lot of unrest and CIA shenanigans to try to determine the next Czar. I don't think A.I. is coming to save us.
@MineralsNinja: btw, been meaning to ask you: what do you think of the current Shemitah year? It ends September 25, 2022. This would be in line with a hugh Q4 crash in the markets, cycle-wise.
