The 'looking forward' so prevalent in the late 1990s was bound to end once the new millennium began. Like some others of that era, I predicted a new focus on the moment, on real experience, and on what things are actually worth right now. Then 9/11 magnified this sensibility, forcing America as a nation to contend with its own impermanence.

It's also hard for people to contend with the difficult possibility that we are simply overadvanced fungi and bacteria hurtling through a galaxy in cold, meaningless space. But just because our existence may have arisen unintentionally and without purpose doesn't preclude meaning or purpose from emerging as a result of our interaction and collaboration. Meaning may not be a precondition for humanity as much as a by-product of it.

We Facebook users have been building a treasure lode of big data that government and corporate researchers have been mining to predict and influence what we buy and for whom we vote. We have been handing over to them vast quantities of information about ourselves and our friends, loved ones and acquaintances.

If you join the Boy Scouts without understanding the underlying agendas and biases of the organization, you might grow up to believe that being gay is a bad thing.

No matter how much control kids get over the media they watch, they are still utterly powerless when it comes to the manufacturing of brands. Even a consumer revolt merely reinforces one's role as a consumer, not an autonomous or creative being.

Our technologies become more complex while we become more simple. They learn about us while we come to know less and less about them. No one person can understand everything going on in an iPhone, much less pervasive systems.

Digital media are biased toward replication and storage. Our digital photos practically upload and post themselves on Facebook, and our most deleted e-mails tend to resurface when we least expect it. Yes, everything you do in the digital realm may as well be broadcast on prime-time television and chiseled on the side of the Parthenon.
