Linux is not just for nerds it is the backbone of the internet as well as just for nerds. Lol.  But most people only use a computer for facebook, youtube, or logging into a school or work website and a document here and there.  That is Linux’s strong point.  Gaming is a different story even if it is getting better, gaming is not perfect.  But standard use of every day humans.  Yeah that is easy.  No command line needed ever.

And additionally you don't get pop ups from the os every 5 seconds. I installed windows recently on a machine and the amount of shit request you get from windows when you install it is ridiculous. The average Linux distro is easy: check timezone, check language, check keyboard, select name and password and done. All your software comes from an app store, easy.
