How do you feel about possible "doomsday"? Let's say... a huge solar flare that will cause a massive blackout? Or something that humans cannot influence in any way? I always had dreams about things like this. About wars, floods, tornadoes, storms, solar flares and similar situations and their aftermaths.
Sometimes, I think the society/humanity needs a reset and it would a good thing.
A "reset" might help with pollution but I doubt that mankind would become inherently "better". Most problems that society faces are part of the human condition and would arise sooner or later again.
IMO People who wish for doomsday scenarios are unable to adapt to the current situation. It's easier to see the world at fault instead of acknowledging this inability to oneself. (No offense)
