Spoiler Golden path discussion:
This isn't meant to be political, but I recently reread the Dune books. They're actually quite brilliant. As I understand it, Leto's Golden Path was many things, among them was a centuries-long effort to remove human patterns and apathy from the human race so we don't' render ourselves extinct.
He essentially "trapped" generations of people in a stale existence that chafed at who we are as warm-blooded animals. He didn't allow violence (except by him) and made the entire human race realize that peace was, in many respects, not what people truly wanted. They wanted good. They wanted bad. They wanted struggle. This is what gives us purpose as opposed to mere existence.
When he was killed, the human race expanded, and became more violent than ever before because of the cycles in human behavior Leto broke, right?
(Again, not trying to be political) I observe today how people are being asked to stay home, and no matter what side you're on regarding that issue, everyone seems to be seeking out the conflict. Everyone is looking for purpose and struggle, even when we could be relaxing about our homes in "peace". Many of us are really having a tough time for various reasons after 2-3 months of quarantine. Imagine the ramifications of being forcefully kept this way for a millennia?! It would definitely take an emperor to force that to happen, though I'm not sure that we'd branch out afterwards, or just be mindless drones.
