I think this is partly why older folks often say something along the lines of "you young people are so /good/ at technology". We've had so much exposure that we've built up a mental model of how even non-intuitive / hard to discover things should work. Sometimes when I update my phone after a number of years or try and operate someone else's phone when they ask for me to "fix this problem" it's hard because of that exact problem, I don't know where or how to access the thing I want.

But it's not all bad; you can't put heaps of buttons on a mobile interface because of the limited screen size and lack of precision with pressing them, so some amount of 'magic' and hiding is necessary imo.
