That's a pretty dramatic take. Social media use in general probably declines with age, and although I'm not sure how you'd quantify it, I bet that using social media primarily as a form of social proofing declines even quicker with age. All young people "perform" because their self-awareness is on extra high alert and their personalities are half-baked. This has been true since the dawn of high schools.

I know middle aged people who do the same thing, their "performances" are appropriate for their age. Pictures of expensive vacations, manicured gardens and so on. Same phenomenon.

That's a pretty dramatic take.

It's just "the medium is the message" applied to Snapchat.
