Well, the article seems mostly theoretical. One of the premises of the article is that the capital owners (who thus own the economy, and the political system, and the legal system and the law enforcement) will give the rest of the people enough to assuage economic anxieties.

We know this premise is pure fantasy. For example Michigan which produces so much food it cannot even eat all of would not provide free school lunches for students: https://www.michigan.gov/mde/news-and-information/press-rele...

It's not even clear that the AI data centers required to run all this will be economically viable in the long term. But again, the interesting part of the article comes after the discussion of any new kind of economy.
