I hope I’m not putting words into the author’s mouth (and I happy to be corrected if I am), but I have interpreted that part as following:

- A lot of value is being generated in service industry, technology, content creation (for balance)

- If AI starts to replace / automate swathes of industries, humans and some companies simply won’t have time to adjust resulting in a net loss to economy. See: horses and automobiles in early 20th century, except sped up x100

- Whatever value was generated by the said industries/businesses is now also usurped by AI companies. In significantly reduced quantities (interconnectedness of economies, less paying customers or users etc.)
