Try this with your friends: work the phrase "fiat money" into every possible conversation, and see if your friends get cramps from rolling their eyes so much.
This is exactly the kind of junk that makes HN the cesspool that it has become. Do you really think that only Tesla can make electric motors, despite it being a mature, 150-year-old industry in which Tesla ships only about 15% of the electric cars? Where Nissan ships product at a dramatically lower price? Did you know that trains and elevators and blenders are also electric, and companies like Alstom and Kawasaki and Bosch make them?
By the way Tesla hasn't made a battery, ever. They are made by Panasonic. Tesla packs them into little metal boxes.
