Jerry Weinberg has an essay on fads in computer programming[1]. Basically, it's written such that you can swap in whatever today's hottest fad is, and the article still makes sense (it was originally written for Structured Programming, but OO Programing, Agile Development, Node.js, et al would fit well within it).

One of his conclusions is that the organizations that are likely to succeed with the latest whiz-bang technologies are also the ones who were most likely to succeed without them. Sure, what's new can be better, but it's hardly sufficient.

Based on my experience, I would agree, and so I think you're right. With the exception of this being specific to "programmers these days". I think our industry has always been plagued by this trend. It's just that now, with the internet, the stories have a longer reach.
