Way to miss the point. His whole argument is that computers and internet-enabled self-service have taken over the majority of the menial labor that travel agents used to do. A travel agent, in case you've never seen one, is someone working in a retail-location shop, behind a counter where they help people plan trips by showing them glossy brochures of hotels, finding the cheapest fares for people, or assemble packages of hotel stays, flights and restaurant visits. Pretty much all of which has been taken over by computers, replacing hundreds of thousands of jobs with tens of thousands of jobs, a large number of which in high-tech with (relatively) high wages. Lots of manual labor by people who aren't very capable are replaced with a few highly capable (or at least highly specialized) people. That's his point, and it's happening in the travel industry, in mail distribution, in manufacturing - everywhere.

(to be clear, I'm all in favor of this - it's progress. It's going to suck being of median intelligence in 20 years though; relatively, someone of median intelligence is going to be worse off as compared to 50 years ago. Of course in absolute terms they're going to have a major advantage, so I don't feel bad for anyone.)
