If AI continues - in terms of job losses - which higher education qualifications will still be worth taking?

Every avenue I find myself going down leads to “humans are no longer necessary for this industry” (or soon won’t be). Of course there are still a lot of things we can do, but my question is, what? For context I’m in my 30s, previously studied psychology just so I could have the university experience. In short, I wasn’t motivated to learn at all. I want to try again but just not sure where to start. My biggest interests are in the fitness industry / interior designs / dietitian. None of these seem to have longevity anymore, so was wondering what people thought still had staying power. God help me if it’s just sales, I did it but boy does sales suck (no offense to any salesman).
