I just think that some people in this community are a little to be evangelical for me. Maybe I’m just old but it seems like throwing him to something as new as Fedora immutable is a bit extreme. You could simply install Linux Mint or Windows 10.
I also don’t think people care much about computers but they do listen to what you have to say. Be careful taking about how great Linux is because people who are less tech savvy may take anything you say as hard fact.
