The lower your education, the more you are at risk of becoming unemployed through AI. Of course, the service industry hasn't been hit yet as much as other industries where a lot is already automated.

Don't agree you need to become a plumber or technician to have job safety. At some point you need an electrical engineering degree to be trained as a electrician eventhough you don't need all that knowledge to learn that profession.

It's true though that when you switch from academia to industry, you have to be able to adapt to the different attitudes and dynamics. In industry, the business needs to be kept rolling; you need to do something inside a certain framework of time and costs. In academia, you have to solve a problem as thoroughly as possible.

As for scorpiosis37's comment. I agree. If you are a good history student, you should be able to get a paid PhD track somewhere in Europe.
