Personal experiences is no longer enough, We rely on a constant stream of inane babble to validate our existence. Communication has become so easy and so cheap that there is no longer any real information contained in what we say. For every one message that relates to a real physical happening, there are thousands more that amount to nothing beyond "I'm here. Are you there?"
As social animals it is natural for us to derive pleasure from interacting and communicating with each other. But we've made this communication so freely available--in fact you're usually considered something of a social pariah if you don't partake in this modern Soma--that we've become thoroughly dependent on it even as it becomes less and less satisfying. All this endless chatter is like a shower that never gets quite hot enough, so you twist and turn to get as much of yourself under the lukewarm communication as possible. The air chills your skin and you stay in longer and longer because you keep hoping that eventually the water will heat up and you'll finally feel satisfied and clean and be willing to step out into the chilly air. But there's no external power, no reality heating the water; it's just the heat of thousands of other tepid bodies, everyone showering with each other's runoff so it never gets above body temperature and we never get clean.
My generation has destroyed information. The world ends not in fire or in ice, it ends not with a bang or a whimper...
But with a Tweet.
