In other words, you forgot a big reason: Hate.
Not much. The world will basically be the same, just different flavors of all we see now.
As long as there is land, resources, woman, money, politics and religion men will fight over all of them. It will be no different in 10,000 years or 110,000 years. Anyone who thinks otherwise does not have a good understanding of human nature.
When humanity awakens, the key will disappear down the drain.
