I’d argue that your last paragraph has the cause-and-effect reversed:
We’re entering into a populist phase because the managerial class is incapable of addressing the problems experienced by most people — so they’re going to try dismantling the current elite systems and rebuilding them. To say that the problem is elites inability to suppress populism is to miss that the elites own chronic failures is what caused the populist surge.
Similar to populist waves circa 1900, where aristocratic systems were replaced with managerialism via populist revolts. Now, managerialism has failed so we’re again seeing the stirrings of change. At a broad scale, communism, fascism, and progressivism were all different technocratic managerial solutions to the problems and excesses of the late 1800s and early 1900s.
I think it’ll be interesting to see what comes next.
The only issue is that - in the past - weapons had to be wielded by people. The same working people that revolted.
There is very strong evidence that this will not be the case by the time this wave you have imagined gets really rolling.
I hope it does not happen for decades yet, because frankly: I cannot see the working class (of which I am part of) win that conflict.
Change does not have to be violent, let alone be a violent internal conflict.
I think between the rise of China, America's reaction to it, and the general shift in economic power to Asia from the west, and the lack of trust in government in the west, things will change.
Currently, weapons and logistics are not automated to that extent; I don’t think it’s meaningful to guess about decades from now, given the current flux.
I’d argue that your perspective means that the time to revolt is now (ie, next few years) — while the technical and social systems are in mutual flux and before a new regime solidifies. A regime that might be more autocratic totalitarian in nature (as you suggest will be the case).
People will reasonably come to different conclusions.
