Things don’t replace things; they just splinter. I can’t tell you how exhausting it is to keep hearing pundits say that some product is the “iPhone killer” or the “Kindle killer.” Listen, dudes: the history of consumer tech is branching, not replacing.
TV was supposed to kill radio. The DVD was supposed to kill the Cineplex. Instant coffee was supposed to replace fresh-brewed.
But here’s the thing: it never happens. You want to know what the future holds? O.K., here you go: there will be both iPhones and Android phones. There will be both satellite radio and AM/FM. There will be both printed books and e-books. Things don’t replace things; they just add on.
