I know that it's probably part of 'grumpy old man' syndrome, but towards the end, I was frequently surprised by the number of people, working in IT, who didn't understand anything in IT.
Your example above is hopefully from people who have to work with computers, rather than people that are supposed to be IT workers, but I was shocked by similar things from IT personnel.
People who treated computers as magic boxes with pictures on them, without even the slightest understanding of what is going on behind the scenes.
Surprisingly, I'm the kid that used to program other people's video recorders for them, and set the clocks on their various appliances. At sixty, I'm stunned that I'm still that person.
(Note that back in the day, the clocks on ovens were mechanical, and people still had that problem)
