This almost sounds like a remake of Street Trash - 1987

"A liquor store owner sells alcoholic beverages to homeless people, unaware of what the bottles actually contain: toxic brew."

Check out Anthony Burgess, The Wanting Seed
"Tristram Foxe and his wife, Beatrice-Joanna, live in their skyscraper world where official family limitation glorifies homosexuality. Eventually, their world is transformed into a chaos of cannibalistic dining-clubs, fantastic fertility rituals, and wars without anger. It is a novel both extravagantly funny and grimly serious."

Written and directed by Louis CK.

But Elon, and Tesla, are rubbish.
