As a younger person in IT, I always hate this argument of "they could never use the old stuff." It's such a dumb thing to use because it can logically be taken anywhere: "these damned boomers couldn't even crank up their car properly" or "I can't believe kids these days don't listen to the town crier and read newspapers instead!" It's just absurd: nobody uses those systems because we found better* options to achieve the same tasks, making knowledge of these things largely irrelevant.

I'd take Norman Schwarzkopf over Napoleon Bonaparte to command any modern military force today as their skills are for entirely different realities.
