The year of Linux has been basically every year since 2003. Virtually every server runs on some form of Linux and with containerization, even the Windows servers are secretly running a bunch of Linux machines though a hypervisor.

The year of the Linux desktop is the one that's a bit of a meme. X11 has been dragged kicking and screaming into to 21st century, but the general consensus now seems to be it's time to take it out back and shoot it. Wayland is quickly becoming the new standard.

It will legitimately become easier to develop desktop applications on Linux once this all becomes standardized. The reason so many companies target Windows is because Microsoft has a ton of proprietary but managed apis for building desktop apps. Ones that are not compatible with X11.
