The author isn't struggling to fathom new job types, he's merely working under the assumption that there's a point where machines will literally do every job better. He's also arguing that automation will outpace the majority of people training to get new jobs. Personally speaking, the future is far too nebulous for me to have a lot of conviction on what's going to happen, so I'm going to accept or discount anything yet.
