> Everything is clear, you know what's a button and what's not. Information density is also high, which is a good thing on a computer screen.
I would say information density was too high. All those always-on indicators: 3D scrollbars, buttons, etc. create a very busy picture. Today's interfaces are much cleaner which comes at a price of less information and hence, more ambiguity, but I for would rather pay that price than go back.
One problem I see is that while the UI itself has been simplified, incidental complexity has crept in other ways. Most importantly, the OSes themselves as software systems have clearly grown ponderous and unwieldy so that today they are more bugs and more of those bugs can be subtle and surprising. Also, there is less uniformity in UX across apps (and UI frameworks).
"Today's interfaces are much cleaner which comes at a price of less information and hence, more ambiguity, but I for would rather pay that price than go back."
If you take today's interfaces to an extreme, you would get a white sheet. Very clean, but unusable. I wouldn't call interfaces "clean" where users increasingly have trouble figuring out what's clickable, how to scroll, move or resize a window.
I think this is a consequence of cultural changes in the last decades. It used to be normal to be able to open a settings window, or any other window, and read it, top to bottom or in any other order, and then you'd know what was there and where it was and which parts you don't care about.
I think it's much better than hidden features practically. But now we've developed this cultural aversion to complex-looking things. Probably started when the iPhone came out with just a flat screen and a button.

Have you been in nature recently? We've evolved to deal with very busy pictures and parse relevant information from them.
New UIs often don't have relevant information - like what is clickable or scrollable - and that's a problem.
It used to be that grandpa couldn't find a button with his poor eyesight, since everything was cramped and too tiny on the small screens we used to have.
Nowadays the clickable label is hidden behind a tiny hamburger menu that you can't tell apart from a mere stylistic flourish on the massive screens we keep mostly empty. Now neither of us can find the button.
That's progress? Every time I open an old application I breathe a sigh of relief because I can feel the cognitive load decreasing. Not having to put myself in the headspace of the designer to figure out what random geometric shape happens to be interactive is like taking a vacation.
