Plumbers and mechanics are harder to phase out. However plumbing is moving towards much easier materials to work with (I can install my own PVC easily, I would much rather pay a plumber if I had to work with metal pipes.) Cars are also moving towards less moving parts and more modular components. Even in aviation it’s getting harder and harder to find someone willing to actually rebuild a mag vs just swapping one out.

The world and the world economy will probably look completely alien to us in 50-100 years. Big changes coming for everyone.
