You presuppose that we know what a good desktop is. I don't think we do. I think trying many different variations to find out is exactly how we some day will.
I currently know of a pretty good one called “Windows 7”... You know, the one with over 30 years of refinement behind it? (And the one that Microsoft is foolishly trying to abandon in favor of a phone interface?)
You can hate Windows as much as you want, but there's no escaping the fact that it's a good desktop (well, until the newbies took over and started the disaster that is Windows 10/11). And being unable to recognize its strengths is one of the reasons why the Linux desktop continues to be the disaster it is today.
