> It still looks to me like Linux 20 years ago. And I started with Linux in the mid 90s. Not much has changed or improved on the pure fundamentals.

Point taken, but that is exactly the quality I said I liked about it. I hope that 20 years from now my desktop will be exactly the same. The disjoint UI bothers me to an extent. I mostly use KDE apps or things built with Qt, but you're right that nothing is uniform. That said, I'd take disunity if it means stability. I don't care if the buttons in different apps look different, but don't take them away. Just look at what they did to Mail.app--in 2010 it was beautiful. Last I used it in 2020 it seemed like all the power user features of it were gone or hidden and everything was under a dot dot dot menu instead of out on the toolbar.
