Multitasking is not a distraction from our main activity, it is our main activity.

A long-distance relationship is, in emotional terms, a bit like culture in the time of Cervantes or Mozart. The costs of travel and access were high, at least compared to modern times. When you did arrive, the performance was often very exciting and indeed monumental. Sadly, the rest of the time you didn't have that much culture at all. Even books were expensive and hard to get. Compared to what is possible in modern life, you couldn't be as happy overall but your peak experiences could be extremely memorable, just as in the long-distance relationship.

Now let's consider how living together and marriage differ from a long-distance relationship. When you share a home, the costs of seeing each other are very low. Your partner is usually right there. Most days include no grand events, but you have lots of regular and predictable interactions, along with a kind of grittiness or even ugliness rarely seen in a long-distance relationship. There are dirty dishes in the sink, hedges to be trimmed, maybe diapers to be changed.

If you are happily married, or even somewhat happily married, your internal life will be very rich. You will take all those small events and, in your mind and in the mind of your spouse, weave them together in the form of a deeply satisfying narrative, dirty diapers and all. It won't always look glorious on the outside, but the internal experience of such a marriage is better than what's normally possible in a long-distance relationship.

The same logic applies to culture. The Internet and other technologies mean that our favorite creators, or at least their creations, are literally part of our daily lives. It is no longer a long-distance relationship. It is no longer hard to get books and other written material. Pictures, music, and video appear on command. Culture is there all the time, and you can receive more of it, pretty much whenever you want.

In short, our relationship to culture has become more like marriage in the sense that it now enters our lives in an established flow, creating a better and more regular daily state of mind. True, culture has in some ways become uglier, or at least it would appear so to the outside observer. But when it comes to how we actually live and feel, contemporary culture is more satisfying and contributes to the happiness of far more people. That is why the public devours new technologies that offer extreme and immediate access to information.

Many critics of contemporary life want our culture to remain like a long-distance relationship at a time when most of us are growing into something more mature. We assemble culture for ourselves, creating and committing ourselves to a fascinating brocade. Very often the paper-and-ink book is less central to this new endeavor; it's just another cultural bit we consume along with many others. But we are better off for this change, a change that is filling our daily lives with beauty, suspense, and learning.

Perhaps what we are doing has nothing to do with efficiency. I don't operate the way I do with the principal goal of speeding things up. My motivations are much more complex and diffused.

I don't perceive what I am doing as multitasking, really. I am not trying to speed up how quickly I shift from one thing to another. Instead, I am involved in a stream of activities, in which other people figure prominently, either synchronously through direct discussion (a la Twitter or IM) or indirectly, through their writings and my responses.

In many cases, I leave activities dangling because I don't know exactly how I feel about them. In some cases, I could resolve my feelings and take some action if I simply stopped other activities and focused solely on that activity, but in most cases that is not the case. And simply forcing myself to focus on the next thing in the activity would not lead to an acceptable or beneficial result, necessarily.

It's like a painter with a number of works in process. My primary motivation is not getting a particular painting 'done', but adding dabs of paint that I feel are the right ones.

If you'll excuse me for jumping on a Techdirt hobby-horse here, this is another example of the economics of abundance at work. Security products are increasingly becoming commodities. Obviously the software ones -- anti-virus tools, software firewalls, intrusion detection systems -- have a marginal cost of zero, and even many of the hardware devices are built on commodity parts that get cheaper every month. What hasn't gotten cheaper is the expertise required to put the bewildering array of security tools together into a coherent system that's customized for a firm's particular business. Indeed, as security products have gotten more numerous and more complex, it has actually gotten harder to keep track of them all and know which security tools are the best ones to use in any given situation.

And crucially, this isn't something you can outsource to a third party. I've written before (in the context of e-voting) that encryption isn't magic pixie dust that automatically makes a system more secure. The same point applies to security more generally. Having the best firewall in the world won't do you any good if it's not configured properly, or if your network hasn't been designed with security in mind. And because every large organization has different security needs, every organization needs a slightly different security setup.

This creates a huge opening for companies who understand that customers are not looking to buy a security software product, but a suite of software that they can count on to be secure without worrying about the details. We've pointed out that this is essentially the business Red Hat is in: not selling software but selling the expertise of its employees with respect to the software. Security is a big part of that. "Security software" is an infinite good, and the market for it will get increasingly crowded in the future. On the other hand, the expertise needed to build complex software systems securely is as scarce as ever, and such expertise is one of the key ways that software companies can distinguish themselves from the competition.
