I don't necessarily disagree but you *can* make an opposite, or at least different, case: subjects based on physics, math and related are a lot more exposed to the possibility of AI-made redundancy, than services jobs (so like your oil and gas example, but think of all the things like medical and educational 'care' expertise). I think maybe the most exposed to danger are in the "middle" between extremes: call it "office work" perhaps.
