I read this article in Wired when it came out in print, and I'd like to clarify that the point of the article is not a hypothetical situation where 7 out of 10 people lose their jobs. The article explores the advent of a proliferation of robots capable of performing complicated tasks. The main point is that we shouldn't be afraid of them "taking our jobs." The farm example is a great way of looking at it. Back two hundred years ago, most people did do manual labor, often on the farm. But technology advanced and slowly people left the farm. But with this change came new purpose for humans. We developed more complicated and important jobs, ones that required skill and use of more refined skills. The analogy is used in the article. Robots performing tasks will lead humanity into more important, more meaningful occupations. I see this as a good thing.
