I think software engineering is like math that requires a peculiar personality and certain talent. However, there's actually a massive pool of these candidates who allocate themselves between different industries as demand ebbs and flows. They end up in medicine, consulting, engineering, manufacturing, academic research, Wall Street, etc and often switch whole industries mid-career too.
