Not sure he's thinking about the entire population
I've heard lots of predictions about what will happen when the vast majority of humans can't sell their labor anymore, and most of the rosy ones don't take everyone into account. Consider these 2 extremes (and this is in the white collar world; blue collar is a whole other kettle of fish:)
1. Hipster full-stack web developer sitting around a cafeteria table with 10 other hipster developers at a San Francisco startup, building web scale apps and getting paid a fortune, living at work doing 16 hour days with basically no concept of a life outside work. These are most often the people who say a robot-filled future will enable humans to have jobs that "don't feel like work."
2. Systems Analyst III, buried in some dark corner of a large corporation or state government, with an extremely narrow focus paper-processing and report-generating job. Their job consists of following the same set of unchanging rules, and is often designed to not allow them to deviate from those rules. (Big corporate IT has more of these positions than people think...yay ITIL!) This employee comes in on time and leaves exactly when their shift is over, has no desire to spend their entire life at work, and often hates their job but needs it and the security it provides.
From my experience in the real world, there are way more #2s than their are #1s. This is going to sound mean, but I think that most people are only capable of holding down one of the #2 jobs, simply because we don't need 7 billion visionary thought leaders and elite scientists. The problem is that modern society is built around middle-level educated white collar workforces coming to an office and processing paper all day long. Millions of students come out of universities every year with a generic BS in "management." Up until lately, large corporations would take in almost all of these graduates and put them to work doing some random task. These students would have something of a career path...associate analyst, senior analyst, supervisor, manager, director, etc...and they would earn and consume at an appropriate level throughout it. Switching everyone to unemployment, a fixed income, or minimum wage work is going to break the consumption cycle. A process-follower cannot be a data scientist.
