I like charts and carry them when flying gliders and light aircraft. They are there as backup, though and I navigate using electronic ones and the view out of the window.
Benefits like airspace warnings, traffic display, frequency selection, NOTAM plots, live weather and terrain profiles make properly designed moving maps such an advance on the traditional flattened dead tree device.
I’m of the opinion that yes, instruction should be given in the use of “classic” charts but after competency has been achieved using modern devices. The sky is too busy these days to learn by your mistakes, especially with lookout and airspace...
