Indeed, but to be fair, lots of people *have* actually thought about it, but have not been able to solve the multiple multifarious complexly knotted problems involved, and instead just have smaller bright ideas -- like those folders/drawers instead of DOS/Unix directories.
Those smaller bright ideas are pitched to us by enthusiasts (and by corporate advertising) as solutions to the issues, but of course they are not, even if focus groups on average react positively. It still doesn't mean that the central issues have been resolved.
Some percentage of people are enthusiastic or persistent and learn *whatever* the paradigm is, and some other percentage remain baffled.
