Yeh the files being little pieces of paper, and the folders being old office folios are skeumorphic. Skeumorphic was (or is?) sometimes used more generically for ui elements made to look physical so perhaps the pseudo 3D shading, dropshadows, bevels and highlights qualify much of OPs examples, though they aren’t representing any specific type of physical object necessarily. Just objects to be grabbed and used (clicked).
I’m sure trends will bring us back to a similar style at some point like they often do.
A global look at Short form video as the latest trend in mass misinformation campaigns, including which interest groups, or states conduct them and who they contract (from large scale to possibly unwitting small creators) to produce and post it. How it developed from prior trends, and where it might go next. Perhaps not particularly controversial (in the true sense of the word), but geopolitically worth looking at and discussing more in imo. Of course a privacy and security focus on this is very much integral to the issue by default. How the existing business models around the data involved (harvesting , auctioning etc) might play into this already , and in the years to come. As well as how other business is implicated. Good old “Follow the money” I guess .
