After decades of development and billions of dollars in investments can we have just 1 distro that works as smooth as MacOS and then we can get back to having 2000 others for that one time we need to run it on a coffee maker
I don't know that that will happen- not even Windows is as smooth as MacOS. But that's because Microsoft and Linux developers are tackling a more difficult problem- getting an OS to work with effectively infinite hardware permutations. Apple has given themselves an easier problem to solve, with just a handful of hardware SKUs and a few external busses.
That said, Android is pretty stable, because a given Android distro typically only targets a small hardware subset. But I don't think that's the kind of Linux distro that most people contributing to FOSS want to work on.
Apple has also yanked backwards compatibility a few times. I bet Microsoft would love to trash a few legacy API decisions from decades ago.
That being said, I still think Microsoft should have developed a seamless virtualization layer by now. Programs prior to X year are run in a microVM/WINE-like environment. Some escape hatch to kill off some cruft.
I had to use it ~2 years for work and am glad that I am back to Linux. The amount of instabilities, bugs, lack of features or removed(!) features between updates, missing software packages, horrible user experience... was just astonishing. You need a lot of fanboyism to cope with that.
