1. Charts don't break down, but they are also out of date the moment they are printed.
2. Who needs to know how to read a chart if you have sufficient redundancy to never have to rely on one? We're no longer taught how to use a sextant, and they dropped Morse as a requirement as I was half way through my commercials. I suggest that drawing lines on maps could, actually should, be dropped - in favour of instruction in how to use the various (and amazing) electronic solutions that now exist.
The reality is that there are thousands of pilots presently being trained, and studying, a system of navigation that they will never, ever actually use the moment they get their certificate/licence.
