Yep, as long as a "strong, smart" dictator is in power things can move along fine, but the second he shows cracks in his armor plate all the people he has fucked over, berated, imprisoned are waiting in the wings to take him down, and then you get instability. That's one reason China was able to survive. Although it's an authoritarian one-party country, the CCP was smart enough to eject the leader every so many years, they threw away that advantage with Xi and declared him dictator for life. Democracies are messy, but they can also be self-correcting by not letting power aggregate for too long around one cult of personality.
