Windows 8 had a "reason"(TabletPCs, and the success of Tiles on Windows Phone) for the changes made. The old UX was still there if you knew where to look and what settings to change; Some searching online could mostly have you back to what you wanted in under an hour. It was coded by humans, tested by humans, and consistently worked as intended.
Windows 11's changes have no such saving-graces or anything resembling rational justification. They let their AI re-code a bunch of fundamental features, and particularly the UI/UX, from a low-level programming language to frameworks intended for fucking websites, just so they could say it was capable of doing-so. Along the way, they used AI to test the results and skimped on or ignored the results from testing done by humans.
How many times before has Microsoft publicly admitted one of their products is broken and promised to fix it? What does being technically solid have to do with UX? EVERYTHING.
