Yeah, I mean desktop environment when I say "UI." It's less about customizability and more about stability for me. Dolphin just crashes way too much for me in KDE Plasma. Like, anytime I do a search. I just go to the command line instead, which is unfortunate for a UI.
Compositing with X server is a mess with multiple monitors running with different refresh rates. Need to try Wayland and see if that's any better.
Also the snap-to on the edges for organizing multiple windows isn't quite as smooth. Still a million times better than Mac OSX.
But, it's open, free, comparable to Windows DE, and yeah you're right, much more customizable.
Also to be fair it's been awhile since I've given Gnome or some other DE a shot.
Playing devil's advocate - it looks like the main advancement made by SpaceX is the reusable rockets. Do you think this has a material benefit to space travel going forward?
In terms of the real economy, I would think this is beneficial.
Devil advocacy aside, I'm skeptical that reusable rockets should take priority over other possible areas of advancement; and of course, the inefficiencies and waste of the private sector should go without saying.
