Interesting to note how much of this is driven by individual billionaire humans being hung up on stuff like ketamine. I'm given to understand numerous high-ranking Nazis were hung up on amphetamines. Humans like to try and make themselves into deities, by basically hitting themselves in the brain with rocks.
Doesn't end well.
Rolling over, covering head with blanket. 'Surely the dystopian future, rich cleansing the world, is still a few decades away, just need a little more sleepy time'.
