What I saw, over a few decades in programming is that: Right off you start off with a split between people who love it, and people for whom it is a job. The jobs people seldom transition to loving it. On the other hand, each few years, a few loving-it people peel off to stable niches and quiet work. It's attrition. And so while I decry ageism (and that kids might think me less good than I am) ... prejudices can be somewhat odds based. Few people really keep on loving it and trying machine learning late in life. Perhaps each paradigm shift (I can use that, darn it!) leaves a few behind.
