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
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.
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.
