So lets see a $60k robot, lets say the whole economy crashes and money means nothing so they just call it $30k for kicks and giggles. Super cheap power since elon owns all the land now, he can have a tiny nuclear reactor every few house lengths. So $1 a day for power : 30365 / 365 days a year is about $80 a day in the first year, or maybe $40 a day assuming the reactors dont melt down for 2 years. So that is about 2 forced cokes down your throat per hour, 4 if you are a "known criminal" who is being robo-babysat. And that is still zero profit for elon because he has to shuffle all his assets around to the next farce of a fucking company
