I think that might be a very valid point in that after a couple of years of 'magenta' all those hard-won lessons on old technology get forgotten and reliance on the new and shiny kit becomes absolute.
Which is why you need to switch off all the fancy stuff, once in a while and do it old style. Not a popular view in H&S dominated industries like aviation, but it helps to appreciate what the fancy bits can and cannot do for you. Ue it when you must, but when you train it has got to come off every now and again.
With regard to using the radar for ground mapping: I never trust the thing to show me what I need to see, so I constantly select short to medium ranges, adjust gain, tilt and mode just to make sure I don't miss anything that might harm us. Low level below MSA, especially at night/in poor visibility is a dangerous place to be. Changing scales and modes also helps in showing something hidden under a waypoint marker. Never take anything for granted ..
