It seems he's reacting to the headline, not the article.

tldr: get off my lawn kids will forever be the sentiment of the current old generation while lol we r so hip will be the sentiment of the 18-20somethings. I don't think this realization is as profound as he is making it seem though, c'est la vie

Profundity is all personalization syntactic sugar these days anyway. La vie.

Wait, what? This made me laugh. May be true, but the way you said it, "syntacti sugar"... So cynical...
