This is a personality thing I think. Some people do want to just stick with what they know by the time they are 25 and would rather be unemployed or in management than learn something new. I'm 45. I've worked in video games for my entire working life. Yet throughout that time I've shifted roles drastically every 5-10 years. This keeps things fresh and it lets me stay employed and in demand without having to become a hands-off manager or sit in the corner working on legacy code.
