@jorge Heh, same thing goes for fashion (they aren't "mom jeans" anymore), which SNL comedians you prefer, shows/movies you quote, and anything else where tastes cement themselves in early adulthood and folks stop searching for new things.
Same phenomenon happens in tech. I can typically guess when someone first got into the industry because their technology choices tend to firm up and stop changing 5-10 years later (depending on when they transitioned to "senior level").
