Kids are always the best with technology. The generation in high school right now will be god tier at getting results from LLMs.
That's not true anymore in the smart phone / tablet era.
5-10 years ago my wife had a gig working with college kids and back then they were already unable to forward e-mails and didn't really understand the concept of "files" on a computer. They just sent screenshots and sometimes just lost (like, almost literally) some document they had been working on because they couldn't figure out how to open it back up. I can't imagine it has improved.
