iPod World: "There are now 22 million iPod owners in the United States and Apple is now becoming a mass market company for the first time. Walk through any U.S. airport these days, and you will see person after person gliding through the social ether as if on auto-pilot. Get on a subway, and you're surrounded by a bunch of Stepford commuters, all sealed off from each other, staring into mid-space as if anaesthetized by technology. Don't ask, don't tell, don't over-hear, don't observe. Just tune in and tune out.

"It wouldn't be so worrisome if it weren't part of something even bigger. Americans are beginning to narrowcast their own lives. You get your news from your favorite blogs, the ones that won't challenge your own view of the world. You tune into a paid satellite radio service that also aims directly at a small market—for New Age fanatics, or liberal talk, or Christian rock. Television is all cable. Culure is all subculture. Your cell-phones can receive email feeds of your favorite blogger's latest thoughts—seconds after he has posted them—or sports scores for your own team, or stock quotes of just your portfolio.

"Technology has given us finally a universe entirely for ourselves—where the serendipity of meeting a new stranger, or hearing a piece of music we would never choose for ourselves, or an opinion that might actually force us to change our mind about something are all effectively banished. Atomization by little white boxes and cell-phones. Society without the social. Others who are chosen—not met at random.

"Human beings have never lived like this before. Yes, we have always had homes or retreats or places where we went to relax or unwind or shut the world out. But we didn't walk around the world like hermit crabs with our isolation surgically attached. Music in particular was once the preserve of the living room or the concert hall. It was sometimes solitary but it was primarily a shared experience, something that brought people together, gave them the comfort of knowing that others too understood the pleasure of that Brahms symphony or that Beatles album.

"But music is as atomized now as living is. And it's also secret. That bloke next to you on the bus could be listening to heavy metal or Gregorian chant. You'll never know. And so, bit by bit, you'll never really know him. And by his very white wires, he is indicating he doesn't really want to know you."

"But what are we missing? That hilarious shard of an over-heard conversation that stays with you all day; the child whose chatter on the sidewalk takes you back to your own early memories; birdsong; weather; accents; the laughter of others; and those thoughts that come not by filling your head with selected diversion, but by allowing your mind to wander aimlessly through the regular background noise of human and mechanical life. External stimulation can crowd out the interior mind. Even the boredom that we flee has its uses. We are forced to find our own means to overcome it."
