I've witnessed this so much over the years. Much of the time when someone would ask me for help with something on the computer, I would have no idea, but I could discover the answer with a little bit of exploration and a good understanding of how UIs are supposed to work.

Windows 2000 was peak Windows UI, and everything since then has been worse.

Then Microsoft started thinking it was a good idea to make native applications look and work like webpages, which was a huge step backwards. Fortunately, that stupid idea didn't last too long, but it did have some lasting effects like the advent of "flat UI" style, but it was the beginning of the modern era of flailing around trying to improve on something that didn't need improving with one bad idea after another.

These days, I sometimes find that _I_ cannot figure some things out in software like Outlook or Teams that should be obvious because there are so many different styles of UI in these tools, many of which are not very intuitive or discoverable. Mixed metaphors, style over substance, and the idea that "flat" is anything but a way to turn your display into a sludge of rectangles of slightly different shades of grey with little or no differentiation between them, and few or no visual cues as to what elements of windows are clickable.

There are certainly things that are better now, like the popularity of "Dark Mode" which took about 30 years too long to happen, but in general, I don't think UI is better than it was 25 years ago, especially after Microsoft wasted 5 years or more on the absolutely misbegotten idea that computers should look like phones. Of course, the legacy is that Windows still has the remnants of about 5 different styles of UI in different places, and I wouldn't be surprised if there weren't a few Windows 3-era UI pieces still hanging around the Control Panel.
