Most of the command line stuff can be avoided. The reason most websites tell you do do things in the command line is because it is the most specific and concise way. You can tell someone "copy and paste this command," instead of "open the settings app, then go to Network, then click on the little plus icon next to VPN, then click on import from file, then go to this directory and pick the file named blah blah blah charlie brown grownup speech noises." This is complicated even further by the fact that depending on which desktop environment or version someone is using, the "open this, click on that menu, choose the third item, click that button" directions will be entirely different, while the copy/paste instructions will always do the same thing. The best way to learn it is really just to fuck around with it - the same way we learned Windows, MacOS, iOS, or Android.
If you have a computer which does the things you need it to do, that's fine. "If it's not broke, don't fix it." There's nothing wrong with that. But technology changes every day. With every change, there are people left behind where the thing did what they needed it to do yesterday, but with the newest boneheaded update from Redmond or Cupertino it is no longer possible. That's what we're here for. We're here to help, not to make people's lives more difficult.
And yet still completely worthless for non-tech people if you don't want to teach people to use a command line and insane Linux stuff.
linux mint, manjaro, ubuntu, etc exist
