We have to make them [workers] more productive through automation, through tools. So I'm convinced that there is in fact going to be a jobs shortage. There is going to be jobs that are unfulfilled, and that the way we'll fill them is to take people plus computers, and the computers will make people smarter. If you make the people smarter, their wages go up. They don't go down, and the number of jobs go up, not down, if you see my point. People keep saying, what happens to jobs in the era of automation? I think there will be more jobs, not fewer.
