I don't think so lol. I'm not a super techy person and the only reason I know Linux is because of my high school boyfriend lol, 20 years ago, who used it. I think he set it up on one of my computers at one point too. I don't think I've ever heard anyone else (offline) talk about Linux π definitely not a common knowledge thing.
It's actually been pretty interesting watching some of the stuff he used back 20 years ago that has started being spoken about more commonly that were just "nerd shit" back then lol. Vpns are common knowledge now, they were definitely "nerd shit" back in the day. Plex is widely used. I'm also glad I still have access to the private tracker he got me onto because that's grown big too, easy as.
But Linux? Nope. I don't think that's entered the common knowledge base. People know windows, android and maybe iOS. I don't even think a lot of people would know what "open source" means.
