When using gnome wayland is already the default in most major distributions already or have been announced for the next major version (such as ubuntu 21.04).
I don't know about KDE more than that they are making progress. If they within a few years make the same transition then pretty much every single default installation will be on wayland. A few moments after that XWayland will become the leading X-server. X will surely live on for decades to come inside wayland, and that is fine. And X will surely be an option for an eternity in some distros. But it will quickly become quite niche, similar to the way systemd has become the mainstream init system.
Maybe so but being the most popular option made Microsoft some money it never actually made it very good. In all honesty Gnome + Fedora + Wayland is a mediocre work compared to windows. At that point the only reason to use linux is cost and given the cost of a license it really isn't a very good one.
I wont feel bad about running a niche distro or even a different OS any more than I feel bad about picking Linux over windows in 2003. There is no accounting for taste and there are probably more people listening to Britney Spears than Beethoven. Its OK if you want to be involved with pop music there is money in it and it still requires the same skills to produce good sound regardless of the artist.
