Computer Files Are Going Extinct
To a computer science teacher, this feels like trying to walk up a down escalator.First-year CS students (middle school or high school) with experience using Apple products don't have a concept of a filesystem. The shift to auto-saving documents also corrodes the intuition that files get stored on disk in some non-magical way. In the same way that it's now easier to teach networking and graph theory because youth experience identity and relationships this way, it's now a lot harder to teach lower-level abstractions. In my experience, this has changed over the last five years.
