Honestly, my kid's slang changes weekly now.

Old school guy" stuff always sounds so serious. Is the difference really that big?

Yeah, that bit about "losing that art" hits home. I read something about airplane cockpit design going the same way, where they kept physical levers for landing gear and flaps because pilots needed that muscle memory in an emergency. It's like the difference between flipping a real light switch in the dark and fumbling for an app on your phone. That instant, sure feel matters more than a clean look when things get tense.
