The first teeth you get immediately after birth just like you get your first opinions from your parents and social environment. Later in life you develop your own opinions just like you lose your original teeth (called milk teeth) and develop more permanent ones that are probably gonna last you a lifetime.
Current me and 14-year-old me would certainly agree that Linux (and free software generally) is awesome for example. :D
Oh I’d likely have thought it was neat, I did find Linux a year later (or maybe I was 14, can’t remember exactly, I know I didn’t start using it until I was 15), but I’ve definitely gotten more, and less extreme on it xD
