You also have GNOME shipping on Fedora and Ubuntu which most new users are going to download, which can't even get their stuff together enough to put a freaking dock and activity indicator on the desktop without having to completely switch to a different activities screen. Asking for a dock will literally get you hung in the village square as people assert that normal users want to use keyboard shortcuts. Everything on the Linux desktop has to either be old fashion or eclectic and tailored to the tech enthusiasts already using it (one of the things that Elementary was actually solving). I tried getting my dad to use GNOME and he gave up after five minutes to go back to his Mac (I can't even launch an app?). It's a mess. Every other distro is basically being held together by a scrappy group of volunteers that are supposed to compete against millions of dollars of investment and armys of full time employees.
I feel bad for Elementary. They made a good product that was actually sane for people coming from MS/A, but they were never going to turn it into something super profitable or even sway companies like Adobe etc. to get their apps running natively on Linux.
This isn't doom and gloom about Linux. Linux owns computing. It's more about how Desktop is niche and not even worth getting into at this point, and how the author has much to gain by just walking away and moving on to other ventures.
Edit:
You can downvote all you want if it brings you catharsis, but you know I'm right. The year of the Linux desktop isn't right around the corner, just like it wasn't right around the corner last year, or the year before that. Linux desktops will always be for enthusiasts, students who want to learn Linux, or people who have to use outdated hardware, which is honestly the way it should be so that Linux keeps its identity and doesn't become yet another replaceable component in a proprietary stack like it is on Android (I'm looking at you Fuchsia).
And no, it doesn't matter that you're reading this right now on Sway using lynx and your mother and sister are using Ubuntu that you installed for them. You are on HN. You are not the segment that makes Linux desktops a lucrative business idea. A software engineer needs to know how to think about market segments and the normal user use cases and not be completely self absorbed into how the world works for them.
