Well, I guess linux is destined for 2% of desktop users, who can use terminal on a daily basis, and current rise is just a fluke.
Dunno what you’re talking about. Most people I’ve seen who have made the switch just go learn how to use the terminal. You’ll have to eventually, since many people have use cases that fall outside the sane defaults of whatever distro you chose, and there’s tons of videos, online communities, and written tutorials to help.
The rest know somebody who can help or just want a system that can do whatever defaults it’s been set up to do out of the box (e.g. open pictures, use a web browser, play Steam games, etc.).
