I can't imagine what gave you that idea. I find there is a small slice of people who actually understand technology and it's massively underrepresented by the younger generations. They have no concept of files/folders or how the computer works at any level. Their views are often half-baked (I know mine were) and the news never actually portrays what the majority are thinking. The news is much more interested in quick hits and shock pieces "Kids are going back to dumb phones" (no they aren't), "Kids are using paper maps" (nope, a few people find them quirky and treat them as art, they aren't using them).
You and he are using “understand” differently. You’re talking about understanding the internals, the components and concepts inside the box labeled “technology”; he’s talking about understanding the externalities, where that box is moving and how fast, how the box affects and alters the world around it.
