the tech community (i.e. us) celebrated the mobile "revolution" and simple (i.e. dumbed down) UIs for more than a decade. You reap what you sow though, you have kids growing up not knowing what a file is. This is no testament to the success of the mobile and dumb-down revolution either: people use their phones more, but the only action they know is scroll and like, so it s not like the UX empowered people, it just steered all their energy to consuming. There is less and less features everywhere, and we are now celebrating new emojis. We are essentially creating a new inequality with the "dumbit down" revolution which pushes people to walled gardens and single-function apps to avoid the pain of learning elementary configuration.

In more concrete terms, Apple is probably the first preacher of hiding complexity behind a mask, and then almost everyone followed, even those that shouldnt (e.g. linux, windows). Gone are the logical, consistent , hierarchical UIs like windows 95, now windows doesnt even have a start menu and you need a search bar to navigate the control panel. Of course people will never learn about a directory tree if they never see one, but those concepts are key and undestanding them simplifies the understanding of just about anything.
