Autocracies are inherently unstable and dangerous in this regard. They have every incentive to be irrational and unwilling to negotiate. They call it “sovereignty”, which it isn’t — just a sparkling dictatorship.
And yet autocracies are historically the most "successful" types of governments. Humans always and eventually end up selecting autocracies with thunderous applause.
There is not much difference in the capability of human experience. I bet a baby born in 494AD, teleported to the modern period and raised by modern humans will be indistinguishable in capability to every other human being.
Autocracies have no place in the modern world.
