Interesting perspective. As a software engineer it is unlikely that the world will ever lack satisfying work for me for very long (recessions notwithstanding). If it does, as a reasonably smart and academically successful person, I think I could transition to whatever is next. Maybe it helps that I saw both my parents change careers via graduate school while I was growing up. But you’re right, it is a gamble, and if I were more risk averse I might want stronger insurance against the possibility.
