The really interesting point is that people don't seem to put any thought into what should be possible with a computer.

Intuitively, people with a decent mental model of how text is processed by computers would expect that the computer could search through that text, and look for a command in the program to do that. But many people's mental model is that they are looking through a sheet of paper displayed on the screen.

How to change this is going to be difficult.
