I pretty much have this conversation with my students. I love it when a teacher is observing me so I start with 'do you ever remember a time before the internet?' of course none of them do, but the teacher does. Then I ask 'do you remember a time when you couldn't talk to a computer' nope, all of them have grown up being able to talk to computers. Haha. Makes me feel old.

People drove busses?! What? And flew aeroplanes?! With other people in them? What if a pilot went mad and flew one out over the sea? Would it disappear forever?
