The unemployed workers are probably the biggest potential AI customer base, as they're going to demand subsidised AI for their entertainment. You have to keep them entertained, or they might riot.

They can spend all day watching AI customized porn and movies, shopping on AI directed websites, having food delivered by AI robots, talking to their AI friends, playing AI-powered video games, building custom AI software only they will ever use, observing the antics of their little AI housepets and helpers, etc.

The government will need to print a lot of money. Nobody will ever do any work, ever again. 😂
