> " “By 2050,” he writes, “a useless class might emerge, the result not only of a shortage of jobs or a lack of relevant education but also of insufficient mental stamina to continue learning new skills.”" Society places a lot of status on position. That becomes a psychological problem when the radiographer has to become a plumber. It is being casually assumed that the reverse scenario is necessary and likely. It is being assumed by most people that the 'useless class' will be the less educated or blue collar class, that it's easier for university graduates to 'update' - but this is backwards if you look at the pattern. Computers displace information processing jobs first. Who does information processing? Who doesn't? Exactly. tldr; Job difficult for you, easy for computer. Easy for human, hard for computer. Consternation from humans ensues.
