It seems that every time a new something or other comes around, it has to be described as a potential "killer" of something else. It's completely annoying.
It's especially bad in technology. It seems like everything has to be a Google, Facebook, Apple or whatever "killer." Why can't something just be what it is, even if it's just occupying a parallel subset of space? Is it because we like the idea of some upstart underdog taking down some established thing? Is it because we're obsessed with the big hits, and anything less is failure?
It's crazy how much people talk about what the biggest and most popular things are. Business is like that, too. A guy can't open a burrito stand that does a few hundred G's a year without someone comparing it or expecting to be the next Chipotle.
