If anything, there's kinda a middle ground age right now where you can expect greater general understanding of computing concepts, with both people young and older than that being more ignorant.
Yep. When I was 2 my parents got an old computer from my uncle's business that he was replacing and set it up in their living room for me. I was learning the command line as a toddler. I'm certainly no guru, but that kind of formative experience was certainly a big part of my choosing this career path. Kids of today grow up with ipads and iphones and have no cause to go poking around and experimenting with the basic functionality of their computers.
Same here, some of my earliest memories are of an old ms-dos mickey mouse game, where you were required to look through a booklet and enter in codes to perform actions.
Learned how to spell quite young to use a CLI, first word was "DOS" lol.
