The exact same trends go round and round in web design.l (and now apps).
At first things were square (because that was all the technology could do) then in the 2000s CSS exploded and everything went colour gradients and rounded corners, juat because people could, then that became old hat and everything went flat and square again, and then rounded came back (but without so many gradients)
Everything is cyclical.
Disco Elysium. Brilliant game.
