To me, the main issue is that many preferred softwares are not offered on Linux because of its small market share. The market share doesn't grow because preferred softwares aren't there. It's a circular problem.
That issue is improving all the time though as new softwares tend to target Linux natively (ex. Discord, Zoom, Slack). Furthermore, the compatibility layers are getting better for non-native programs (ex. Steam deck).
I really don't see a universe where Linux stops taking over the world, including the desktop. Adobe and Excel probably can't hold Windows up forever.
You've been able to do both on Windows and macOS for other a decade now without touching a terminal.
or repair a broken install etc
And for zoom, in addition to asking you to select your 'linux type,' has this little gem: "Zoom's rpm packages are signed with a GPG key. Please run "rpm --import package-signing-key.pub" to import the key in case package management utility asks for a missing public key" - though I guess probably the auto-installer thing would run when you opened a zoom link and skip all that. I doubt it's the only time a linux user is assumed to know what a terminal is or expected to know how to use it.
On the other hand - for linux - WSL is pretty cool. That's definitely a lot of linux on a lot of people's desktops, whether or not they use it!
All hail the year of the linux desktop!
