Absolutely. My kid just finished an engineering degree from a well respected institution. Early on in the intro programming classes, about half of his class was unfamiliar with file system structures. Chromebooks and iPads in school and at home meant they had never really encountered them.

There were plenty of other "techy" things that older generations take for granted but kids aren't learning about unless parents show them because they are hidden behind modern OS/software interfaces and usually locked down to prevent discovery.
