I’m 85, and while we had chat rooms and IM in high school, and a few kids probably had LiveJournal, 2003 was really the beginning of social media as we know it, with rapid adoption in 2004+. Texting wasn’t really a thing before ~2000, and not a very popular thing until at least mid aughts because of pricing. I think every young adult basically had a mobile by 2005.

So I think there is some real line right around 85/86 where, for those younger than that, technology/social media as we know it today, didn’t exist in High School.

Other examples would include Google.

Also, for my age, Wikipedia was really emerging during college and exploding/maturing at the end (2007). If you were born, say, after 88, you would have started college in the wikipedia era (and those born after would have had it available in high school)

That said, I think you could unequivocally say that those born after ‘90 are much different than those born before ‘85, but between those years it’s a little bit muddy.
