The average person is extremely tech illiterate. This is not a condemnation of their personal choices, or view of the world, or politics or anything like that. Even highly educated people cannot explain even the most basic things about computers, the internet, electricity or the nature of information.
Linux feels simple to you because you likey have both education and experienced with computer systems. However, the interconnected world is not that difficult to understand if you have the opportunity to understand it. This privilege absolutely makes everyone else in the world who does not have that opportunity or desire feel shockingly inept on technology issues.
