> To you and me, sure, there is value in a linux desktop.
"You and me" is actually not a small or meaningless demographic. It includes my thousands of colleagues at Mercedes-Benz who use Linux desktops to do engineering work, and millions of other developers. It means a lot of scientists, for example at NASA and CERN. It means a lot of school students and government employees in educational and other municipal deployments.
A lot of the places where Linux is used is for roles that act as multiplicators, e.g. in the development and production of end-user products, or research/science/RD that will lead to new ones, or in educating the people who will one day make new ones.
All of this is a lot of value if you sum it up. There may be no single shining CEO and his shareholders getting rich off of the Linux desktop in the way we're used to fawning over in the tech hustle news cycle. But the world at large almost certainly is. I submit that's a fine success metric.
> To the average user, linux is not in any state to be a useable, daily driver desktop.
For many users it's today more reliable than contemporary Windows. Ten years ago, the Linux desktop experience for a non-technical user was death by a thousand papercuts. Today there are still some gaps in HW support that can create unsolvables, but if your machine is well-supported, things work just fine.
What's mainly keeping it back is many other factors, from channel availability to software availability.

:-) I worked on the Steam Deck as CTO of one of Valve's contractors on the project. Glad you like it.
