User interface will remain a dumpster fire until we have LLMs (or whatever) helping us. "Computer, stop doing that weird sudden thick blue border thing on my Firefox window, what the fudging heck?!" To wit: suddenly having a thick blue border around you Windows windows. According to the internet, it could be just about anything. Fwiw, in the end in my case it was PowerToys always-on-top keyboard shortcut that was enabled by default and that I did not know about and that I do not actually even want. Turning that off fixed it. (I do actually like PowerToys a lot for the keyboard manager, otherwise.)

I do hope that the current AI push will get us ways to build computer systems that aren't quite so bad. It seems like pretty much everything I use has major, glaring issues. Or at least a long list of UX slings and arrows that all add up to make life unfun. Consider the Unreal game editor's undo. They've managed to take something that was a god-level genius UI UX idea, from the I dunno Xeroc PARC days, or 1968, or something, and turn it into something with dangerous spooky unclear action evil at a distance results. You really do not know what it will or just did undo. It could have undone something in a far away foreign land for all you can tell. It certainly often doesn't undo whatever I was just doing in my Blueprint, that's for sure. (And as far as I can see there's no Photoshop-esque command history panel?) It is all just incredible to me how much they have turned something so good into something so bad. Thus I hope we can get to the point where our AI systems let us quickly build and fix the software we want. Heaven knows mortals can't ever do it right en masse.
