anything replacing Windows/MacOS for desktop purposes any time soon
It's heavily depends on what you mean under "desktop purposes".
For me, Windows and MacOS are crap for "desktop purposes",
and are unusable. But GNU/Linux (non-systemd Devuan) and FreeBSD are
great desktop operating systems, and satisfies me 100%, I use lightweight environments
on both, FVWM as a WM, Pcmanfm as a FM, Vim/GVim as an editor, etc
(I used minimal installation with Devuan, without any environments.
Devuan is a little bit better than FreeBSD BTW,
for desktop purposes,
because many
.deb packages are available prebuilt on many sites,
also many proprietary software are also available. And this will never be available
for FreeBSD, if things won't change, why some company will build packages for FreeBSD,
if even its developers don't use it as a desktop OS???)
But of course, for a regular "average user" Windows and MacOS are better,
because they are not able to use *nix OS-es fully, only Ubuntu, or some another
*nix OS with GUI, but such OS-es are crappy for now.
