That's because the aim of computer design in the few decades has been to turn such things into implementation details. If your primary computing device is a phone or a tablet you have no idea, and /no need to know/, what your photo's filename is. It's just there in the app and can be easily shared, edited or printed from there. The question is -- is that a bad thing? For the majority of people a computer is a means to end and the fewer implementation details exposed the better. Just as I don't really want or need to know how a car works in detail in order to get from A to B. What I see happening is that computing knowledge becomes more and more the preserve of specialists and that's a good thing. When I started to learn programming I read about why the command line was so useful and people were saying things like "you can batch rename files really easily!". But the only times I've ever really had to do that are programming-related tasks such as log files etc. Most people simply don't need to do that often enough to justify learning how.
