That's very much an oversimplification - in pre-industrial society the majority of labor was involved in food production. At the current scale of farming, I don't see this happening. The article is very poorly written, but I think the concern it is trying to hit on is what happens to the economy when too many jobs are automated out of existence and the overall employment plunges. Personally, I'm optimistic that the society will adapt, as we have adapted to the industrial revolution, but we need a healthy debate to do so.
