Sure, for power users and people who have used the same UI for over a decade, the changes do not seem to make any sense. But that's why there's options to re-enable legacy UI, as seen in TFA. I suggest you give a laptop to a normal person who doesn't spend time on the computer and see how they use it. Give them a task that doesn't involve using the browser. I'm pretty sure you'll be surprised how easily they get lost in the UIs. These "minimalist" UIs actually do have a use for people who struggle with basic usage of their OS outside the browser.
