I’m aware of students that no longer attend university lectures, preferring instead to watch their lectures online at 1.5x speed (going backwards if they don’t understand something). However, I was having a chat with someone today and heard a new twist on this. Someone they know doesn’t have time to read their small child a book at bedtime. So the child has been given various audio books (or maybe the child found their own audio books I can’t recall) and the kid listens to bedtime stories at 1.5x speed.
