For me, the year of Linux on the Desktop was '94. It's been my main desktop at home ever since, and for wor as well the majority of time - but with some obnoxious detours.
Not advocating for 2024 (or 2025) but I still think someday it will, having seen multiple usability and feature improvements. (Not only talking about wayland here)
Wayland is going to make 2024 the year of Linux on the Desktop!
Any day now...
