Until recently, technology made low-paying, undesired jobs obsolete at a pace that made it possible for more jobs to be created by new industries than the industries that have been disrupted by them.

We are now entering a period in which middle and high paying jobs being replaced by machines. High-frequency trading replaced a whole profession in the financial sectors. There are now machines that are capable to analyze an x-ray image and determine the cause of the problem, leaving the doctor with "just" the job of delivering the news.

So, yes, we do have a problem. I'm not a Neo Luddite. The purpose of this is not to destroy the Internet and all the machines, but I do think that we need to have an ongoing debate about the social structures that we are dissolving as much as about those that we want to build up.
