Trends come and trends go. People jump on completely insane ideas because everyone else is jumping on them. I get it. It's been that way since the dawn of time. Pet rocks. Lava lamps. Halter tops. Pink Floyd. All kinds of things become things because - for whatever reason - a few people decide to ride them and everyone else follows, until it's time to jump off and jump on something else.
(And sometimes we jump off things we should stay on forever, like Sonny Crockett's wardrobe, but I digress.)
For the most part I attribute it to a uniquely human aversion to engage in critical thinking. "This is idiotic but everyone else is an idiot too so who cares?" It's easier than thinking, and it earns you less resistance, so what the hell?
