Nope. As long as i'm alive ima be giving cacs hell. Can't be no world piece damage has been done.
But i think that if the human race continues to prosper and evolve we'll eventually get to a point where life is so easy we won't need to fight. Everything will be at our fingertips. No need to even work. After a few hundred years of that i'm pretty sure its gonna be hard for anyone to really harbor hate.
But at the rate where going idk if we'll ever reach that utopia. Gotta be at least like 3 apocalypses between then and now breh. So i'll say 1,000-3,000 years maybe.
Then again maybe never. We all know who controls the world and they seem to like keep their feet on peoples necks. If thats the case there will always be fighting until they are, ERADICATED
