I have witnessed other people do it at multiple companies and even been guilty of it myself once or twice.

I sat at the end of a long board room table full of senior engineers and directors and was the only one who didn't bring a laundry list of techs he was waiting to introduce.

I have seen older developers treat design patterns the same way that younger developers treat JS frameworks. Everybody wants to believe they have a toolbox full of solutions to problems. Maybe for the last generation it was Gang of Four, and for this one it's the HN front page and blogs.
