Contractor, plumber, renovator, physical jobs in unpredictable environments are going to be the hardest to replace.

But also I would focus on areas of growth. Mechanical engineering could be good as it applies to robotics which is going to be absolutely huge very soon. Better would be even some kind of specialized robotics degree. Not that these jobs are not going to be augmented by AI, they will be, but there will be huge demand that won't stop until almost everything is automated.

I also think software engineering is gonna do ok, yes, it will be heavily augmented by AI, but as price of software plummets due to productivity gains it could open new avenues of applying software, or improving software, areas for which it is currently too expensive. Robotics is large;y software as well. But the best days are probably coming to an end, sadly. But who knows... Machine learning experts are probably gonna do very well for some time.
