I have a feeling that Liquid Glass is just made for a younger demographic than most people complaining about it right now, and I don’t mean this disrespectfully; the design field has always been brimming with the ideas of young designers, and I’m pretty sure it’s the same thing at Apple.
All the affordances and interface clues we used to have were made with users in mind that had low familiarity with digital interfaces. It’s different now. Children that grew up with iPhones don’t need them; just look at the Instagram app. It’s confusing the hell out of me: you can swipe everywhere, click things that don’t look clickable to me, there’s nested menus like five layers deep. And yet, every single teenager out there is navigating this mess easily.
So I guess this just means the world is changing in a direction many older people don’t like too much, and I don’t really know what to make of that yet.
This isn't true in my experience. They're just used to interfaces being inscrutable by default, so tap and swipe around until something works. And of course they learn how to operate an app like Instagram if they use it all the time. Even the most confusing UI can become muscle memory if you use it frequently. That doesn't mean that it suddenly is good UI.
I never said it was good, just that it follows different paradigms than what older generations are used to.
