I never said you were stupid, but you do sound supremely arrogant, though…
It’s cool that you know DOS, though. And man, Win95 is nostalgic as hell, used to use that as a kid/teen… Used to play Diablo and Wolfenstein.
But Mint isn’t necessarily the best intro to Linux, though. It’s pretty good, but there are better options for getting started from Windows. Consol is still something people need to get used to, though, since most people haven’t used DOS for a loooooong time, except computer nerds like us.
And I know Linux is based on Unix, developed by Linus from neighboring Sweden, hence the name (it’s a bit more complicated than tat, but no need to clutter the forum with another text wall).
Having a coding club is cool, but don’t be arrogant about it. Stay humble, then you’ll stay a good teacher, and not push people away. When you get to university and see some professors, you’ll know what I mean. But teaching is fun when it’s something you’re passionate about. Sharing knowledge is always great.
