Some things push UI and thus UX into new, good, territory. Like when the almost entirely touch based iPhone first came out. Other things, in my mind, push UI and thus UX more towards a regressive dark ages. Like when scroll bars disappeared and/or became really skinny small in Mac OS X. Or when Gnome decided that left-click in a scroll bar shouldn't page down any more but go directly to the click. Or when Mac OS X decided the maximize button should mean full screen rather than plain old maximize. Or when Google Voice decided there should no longer be a way for me to easily delete / clean up the visual clutter of all the old useless conversations. Or when Asana turned evil. I think there's some kind of jumping the shark that happens, for various reasons: Sometimes because some person apparently thinks it really is a good idea, or that they can "make their mark" on the world that way, I guess. Or maybe all the millennials are wanting everything full screen all the time according to the data that Apple has reaped and so that's why they changed it, and I just don't see eye to eye with the kids on my lawn when it comes to UX.
