I feel like the people I interact with irl don’t even know how to boot from a USB. People here probably know how to do some form of coding or at least navigate a directory through the command line. Stg I would bet money on the average person not even being able to create a Lemmy account without assistance.
Linux is second nature to us geeks, so it’s easy to forget that the average person probably knows just Ubuntu or Fedora.
And Debian GNU/Linux, of course.
