So much of it is a problem of execution. If people could use Linux without ever having to know what a terminal is (much like the average Windows user doesn't know what PowerShell is), then it would actually be quite successful. It has gotten better over the past decade, but it still suffers from endless paper cuts and the odd issue that requires a shell session to fix. I will say that Valve's SteamOS has come the closest to avoiding this trap. You can use a deck without ever having to touch a CLI.
