I completely agree that as it is now, Linux is a tool, suited to a variety of purposes, hard core gaming not being one of them. That being said, I have nothing against people who wish to spend their time and energy to make it suitable for a wider range of purposes. Linus came from the POV of a random gamerbro trying to get stuff running (with some exotic hardware) and he actually managed to point out some valid UX flaws.
The way I interact with computers as a dev is different than of other users, it’s refreshing to see a different perspective.
I love it!
