I'm quite disillusioned with desktop computing in general. Microsoft and Google are leading the way with "enshittification" (https://en.wikipedia.org/wiki/Enshittification), and the Mac experience in 2024 isn't like what it was in 2009 when the Mac was at its peak, in my opinion. The Linux desktop ecosystem suffers from a lack of funding relative to its commercial peers, combined with the "organization from chaos" that comes with bazaar-style development. The X11 to Wayland transition would be easier to pull off if the Linux desktop has Microsoft- or Apple-levels of funding and cooperation, but such funding doesn't exist, and part of the characteristic of the bazaar is that developers and teams of developers get to work on projects of their own interest and its the community that "votes" on projects by using them. The bazaar definitely exhibits freedom, but the major downside is that major changes in infrastructure (such as the X11 to Wayland transition) could take a lot of time and have major pain points (for example, the development of incompatible Wayland compositors and the fact that the X11 concept of a window manager doesn't exactly translate to Wayland's concepts).
I love free, open source software, but I'm drawn more to cathedral-style projects such as the BSDs and HaikuOS where there is a coherent vision for the system. Unfortunately the BSDs are dependent on the broader FOSS ecosystem for desktops, which is dominated by the GNOME/KDE/Wayland ecosystem (which also priorities Linux and treats other Unix-like operating systems as an afterthought, but that's another discussion). I'll need to re-investigate HaikuOS to see whether it can be used as a daily driver today; I've seen that a lot of attention has been given to HaikuOS in recent years.
I'm slowly working on a side project where I'm implementing my dream OS, which is influenced by various alternate paths of workstation and desktop computing explored in the 1980s and 1990s but were overtaken by Windows and Unix, namely Lisp machines, the Smalltalk environment, and 1990s Apple initiatives such as OpenDoc and the original plans for the Newton, which involved a Lisp OS (https://mikelevins.github.io/posts/2021-07-12-reimagining-ba...). But I have a busy day job and so this will take years of effort on the side.
