Not a fair comparison. Unlike shoemaker or coopers who do ONE thing, a SWE doesnt do just one thing.. atleast in general. I churned through basic, logo, c, c++, java, c#, python, go and now agents. The executable building on single machine died when distributed systems came in. It again evolved when cloud took over. We have been reinventing our work every few years. Every job change requires us to learn new skills.

How much did a horse farrier have to learn if they switched their employers?
