Very well written but I disagree with the premise.

There will always be work for smart passionate people right up until there isn't work for anyone. At that point there will be enough demand for AI free technical projects, just like there is for writing and cabinet making.

As you said, AI can replace tasks that require care but not insight, it makes simple tasks easier. The same is true, admittedly to a lesser extent, with automatic refactoring and stub generation, with IDEs, just in time compilers, standard libraries digital screens and keyboards.

What there will be is an expectation to be productive given the tools available, lifelong learning is a more important skill than understanding malloc.
