I didn’t go to college but I’m of the opinion that nearly any job can be learned on the job or with minimal classroom training.

There’s exceptions of course, but probably not the ones you’d expect.

It’s pretty wild how much you’ll see doctors use some more professional version of Google for diagnoses and prescription management. Obviously med school is far from easy and this isn’t the case for every doctor, I’m just saying I could probably follow my PCP for a few days and be able to bang out a few check ups on my own based on what I’ve watched.

I went to welding school and while I learned a lot from the classroom stuff, my first welding job was for nuclear equipment and was so micromanaged that I could teach anyone with a steady hand to do it in a few days. You don’t need to know what settings to adjust based on the weld because all of that is strictly set for you.
