The real reason programmers don't age past 30.

 Lions have slowly realized the reason programmers never age past 30 is less to do with burnout or lack of interest & more to do with them having enough money to retire at a much younger age than other industries. Most of them did exactly what they were told, invest in index funds. Over a 20 year period, there are going to be crashes, but there's always going to be a boom. Most lion coworkers made 300% on what they invested in the good years, 500% from what they invested in the bad years & gave their commutes a rain check at 40. The ones still working only stayed around because they're at a very high job title or they invested very poorly.

There is age discrimination, but it's an effect of everyone retiring much younger than other industries. If everyone stayed in cash & was still starting from scratch after 40 like Walmart employees, there would be discrimination against everyone under 40. Because most people eventually hit paydirt at a young age in this industry & can retire early, they're always going to be manely under 30 & they're always going to prefer hiring people their own age.
