there’s a big ol’ it depends. my wife (a teacher) has her smart watch run her daily timers to keep her class on schedule. and that way she doesn’t have to pull out her phone and then her class doesn’t yell “mrs ymca no phones at school” every time, because you remember being a student. i know a lot of nurses who wear smart watches for other but similar reasons. the convenience of being able to receive (and maybe send? i don’t know, i don’t really wear watches.) texts and alerts from your phone can be rather useful in some fields.
