The mere presence of buttons that look like buttons, and static text that looks like static text, is innumerably better than the "ambiguous text and icons floating in a sea of flat white/blackspace" that UIs today seem to mostly consist of.
I feel this way about interactions on mobile. I grew up using Android and still have my phone on 3 buttons mode because it seems obvious. Have been using iDevices for work and some of the tap and swipe gestures are so unintuitive, along with the flat text as buttons. It feels like Apple decided "people that use our devices know this already."
There’s an accessibility option to display buttons with an outline. I have enabled that for some relatives as they are also confused by the (lack of) design. All hail flat design, sigh.
A lot of that (dis)credit historically goes to Jonny Ive. Every UI mostly just copied the flat, glassy look. KDE had flatter icons - but not in such disruptive way. They were still skeumorphic
