This is so true. I find Google/Gmail also have advanced shortcuts that stem from unix style, and I could not imagine not being able to use J/K to rapidly select lots of email messages for bulk actions. I enabled this on my parents account, and years later they still are mousing through each message individually, as if I never showed them how to do it. Even copy/paste shortcuts elude them.
