In my experience this is also the biggest obstacle facing older people using modern devices like smartphones. I try to explain that when they're confused they should just poke, press, or swipe something and see what it does. Some older people are simply unable to do that. It's just a machine; it doesn't care if you hit the back arrow a lot! Relatives of mine have written long lists of instructions in preparation for smartphone use on trips.

In fairness, this is similar to many young people when forced to drive in less familiar areas without GPS.

I taught a "computers 101" lab with several adult learners many years ago, and I had one student walk out when I told him I simply couldn't teach him exactly what to do in every situation.

I felt badly, and I'd probably with 20 more years under my belt be able to help a bit more now, but it's still the same quandry: you can't expect to use any computer/mobile device without experimenting to figure out the way to do something, and there are a lot of adults (I assume some children too) who aren't willing to do the wrong thing.
