While I upvoted this, as being true for the general population, for me Linux has made it on the desktop (and laptop) much more than 2 decades ago, around 2003, when the remaining problems that had forced me to use dual-booting with Windows had been solved (i.e. when it became possible in Linux to play movies, read DVDs and use TV tuners). When that happened, I wiped out Windows from my computers.

If you have a pro to help you, already for a long time Linux has been fine on the desktop for anyone. My parents, over 80 years old, have used Linux on their PCs for many years, and they did not even know what "Linux" is. That was possible because I installed and configured for them the operating system and all the applications they needed for reading and writing documents, Internet browsing, e-mail, music listening and movie watching etc.

Windows is easy only because it comes preinstalled. I have installed Windows at work on many kinds of computers and during installation I have encountered much more problems impossible to solve for a non-expert than when installing Linux.

Linux has made it to the desktop, packaged inside VMs served by Apple, Microsoft and Google.

As a sign in the window of a tiny shop in my quiet suburb says "Laptop and phone repairs - Windows, Linux and MacOS". If that doesn't count, I don't know what else could.

Linux hit 10% desktop usage recently

Eric S. Raymond opines that now that Microsoft makes its profits mainly from Azure, some product owner in Microsoft will be allowed to enshittify Windows for collection short-term profit, thus paving way for Linux on the desktop.
