I have a hard time accepting that some of those are what trips people. That a something called “file” is in one place (device or particular location) seems more readily understandable than an ethereal thing that’s (sometimes, to some degree, at some resolution) ubiquitous.

The format topic is also something that I see causing frustration, but it is not complicated to understand, as long as someone is familiar with the concept of incompatibility (screwdrivers, human languages, etc.)

In my opinion at this day and age is more an issue of “never needed to learn / cared to” than that of “it is difficult to learn”.
