These projections always read like something that would come from a person who doesn't understand where their food comes from, how much work goes into building and maintaining their housing, or that most people's preferred entertainment options require a lot of work to produce.
I could see us arriving at some of these extreme estimates if everyone universally agreed to eat the cheapest synthetic food we could produce with the most automation, live in the most bare-bones housing, and exclusively choose free or cheap entertainment and hobbies. But in the real world, it takes a lot of work to get food to people, build and maintain housing, and the things people like to do and own are also labor-intensive to produce at various stages.
There's definitely more room to squeeze labor out of the market through more automation, but that doesn't result in higher wages for people.
