Mobile notifications put people in a state of perpetual emergency interruption - similar to what 911 operators and air traffic controllers experienced back in the '70s and '80s.

I don't think tablets are where we should be focused. But I do think they could end up being an efficient way of delivering textbooks. They're just not really that, yet. There's all sorts of poisons and mined minerals and carnage that goes on to make a tablet. Way more than to print a book. Or a bunch of books.

The easiest way to figure out who the customer is in an online space is to figure out who is paying for the thing. Usually, the people paying are the customers. So on Facebook, the people paying are marketers. That makes them the customers. And it means we are the product being delivered to those customers.

I do remember the moment when, as a child, I realized that the things we call 'TV shows' are really just the stuff that gets put between commercials. Later, I came to see that the kinds of things that get on 'free' TV are shows that help sell products.

Imagine what it would be like if you didn't know that the evening news was funded primarily by 'Big Pharma.' You would actually believe the stuff that they're saying. You might even think those are the stories that matter.

On Facebook, your past comes into your present when someone from your second grade class suddenly pops up to send you a message, and your future is being manipulated by what Facebook knows to put in front of you next.

When digital culture first came along, it was supposed to create more time, by allowing us to shift time around. Somehow instead we've strapped devices to ourselves that ping us all the time.

The horrible truth is we are linear beings; we can't multitask, and we shouldn't keep interrupting important connections to each other with the latest message coming in.

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.

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.

As a digital technology writer, I have had more than one former student and colleague tell me about digital switchers they have serviced through which calls and data are diverted to government servers or the big data algorithms they've written to be used on our e-mails by intelligence agencies.

I'm not a communist, just a media theorist.

Invest in people who will take care of you when you're old.

Overwinding happens when hedge funds destroy companies by attempting to leverage derivatives against otherwise productive long-term assets.

A currency designed for long-term storage and investment doesn't do so well at encouraging transactions and exchange in the moment.

Unlike the Tea Party, who see themselves as the customers of government, people in the Occupy Wall Street movement understand that we are the government. Stated most simply, we are trying to run a 21st-century society on a 13th-century economic operating system. It just doesn't work.

It's easy to make fun of AOL's pending purchase of HuffPo. Just like AOL's purchase of TimeWarner, here we have a new media company - Huffington Post - fooling an old media company, AOL, into overpaying for something that has already peaked.

Walkman was the precursor to the cell phone, in terms of your strategy for getting through the urban landscape and the modern experience. Insulate yourself from it with your own soundscape.

As popular culture becomes more presentist, we move away from entertainment as the vicarious experience of a narrative - as watching someone else's story - and much more toward enacting one's own story. Moving away from myths and toward fantasy role-playing games, away from movies and toward videogames.

With the DVR, I was mostly writing about it as a good thing in giving us the choice of when and how to watch things. But there's what we lose in the bargain, which is the collective spectacle. 'Did you see Jay Leno last night?'

I went to Cal Arts and AFI, and I worked on 'Bonfire Of The Vanities.' I got this grant from the Academy to be Brian De Palma's apprentice director. And it was such a harrowing, disillusioning, awful experience.

Occupy Wall Street is meant more as a way of life that spreads through contagion, creates as many questions as it answers, aims to force a reconsideration of the way the nation does business and offers hope to those of us who previously felt alone in our belief that the current economic system is broken.

The faux now of Twitter updates and things pinging at you - all the pulses from digitality that we try to keep up with because we sense that there's something going on that we need to tap into - are artifacts, or symptoms of living in this atemporal reality. And it's not any worse than living in the 'time is money' reality that we're leaving.

Time has always been used against us on a certain level. The invention of the clock made us accountable to the employer, gave us a standard measure and stopwatch management, and it also led to the requirement of interest-bearing currency to grow over time, the requirement of the expansion of our economy.

The industrial age was not about craftspeople trading peer to peer. It was about stopping that. You weren't supposed to be a craftsperson, you were supposed to be an employee.

New technologies are wreaking havoc on employment figures - from EZpasses ousting toll collectors to Google-controlled self-driving automobiles rendering taxicab drivers obsolete.

Every new computer program is basically doing some task that a person used to do. But the computer usually does it faster, more accurately, for less money, and without any health insurance costs.

Jobs, as such, are a relatively new concept. People may have always worked, but until the advent of the corporation in the early Renaissance, most people just worked for themselves. They made shoes, plucked chickens, or created value in some way for other people, who then traded or paid for those goods and services.

The hours Facebook users put into their profiles and lists and updates is the labor that Facebook then sells to the market researchers and advertisers it serves.

If the clockwork universe equated the human body with the mechanics of the clock, the digital universe now equates human consciousness with the processing of the computer. We joke that things don't compute, that we need a reboot, or that our memory has been wiped.

In the digital universe, our personal history and its sense of narrative is succeeded by our social networking profile - a snapshot of the current moment. The information itself - our social graph of friends and likes - is a product being sold to market researchers in order to better predict and guide our futures.

Occupy is anything but a protest movement. That's why it has been so hard for news agencies to express or even discern the 'demands' of the growing legions of Occupy participants around the nation, and even the world.

Think 'Game of Thrones.' In the old days, this sort of show might be considered bad writing. It doesn't really seem to be moving toward a crisis or climax, it has no true protagonist, and it's structured less like a TV show or a movie than a soap opera.

I think there can be a positive sort of futurism even in a presentist society. But I think it's a kind of futurism that envisions augmenting human ability and intellect rather than creating some artificial machine intelligence that displaces us.

While learning to code may have once been an arduous or expensive process, the college dropouts who developed Codecademy have democratized coding as surely as Gutenberg democratized text. Anyone can go to Codecademy and start learning and creating code through their simple, fun, interactive window, for free.

Digital technology is both arousing and distancing. We don't look at the users on the other side as people. They aren't - they're just usernames, Facebook photos and Twitter handles.

Remember when those CD-ROMs from AOL came in the mail almost every day? The company was considered ubiquitous, invincible. Former AOL CEO Steve Case was no less a genius than Mark Zuckerberg.

Social media is itself as temporary as any social gathering, nightclub or party. It's the people that matter, not the venue. So when the trend leaders of one social niche or another decide the place everyone is socializing has lost its luster or, more important, its exclusivity, they move on to the next one, taking their followers with them.

It's not that MySpace lost and Facebook won. It's that MySpace won first, and Facebook won next. They'll go down in the same order.

No matter how invasive the technologies at their disposal, marketers and pollsters never come to terms with the living process through which people choose products or candidates; they are looking at what people just bought or thought, and making calculations based on that after-the-fact data.

Like the diminishing beauty returns for a facially paralyzed Botox addict, the more forcefully we attempt to stop the passage of time, the less available we are to the very moment we seek to preserve.

While we may blame the Internet for the ease with which conspiracy theories proliferate, the net is really much more culpable for the way it connects everything to almost everything else. The hypertext link, as we used to call it, allows any fact or idea to become intimately connected with any other.

New content online no longer requires new stories or information, just new ways of linking things to other things. Or as the social networks might put it to you, 'Jane is now friends with Tom.' The connection has been made; the picture is getting more complete.

Marketers use big data profiling to predict who is about to get pregnant, who is likely to buy a new car, and who is about to change sexual orientations. That's how they know what ads to send to whom. The NSA, meanwhile, wants to know who is likely to commit an act of terrorism - and for this, they need us.

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.

Google did a great job hacking the Web to create search - and then monetizing search with advertising. And Apple did a great job humanizing hardware and software so that formerly daunting computers and applications could become consumer-friendly devices - even a lifestyle brand.

Beyond the hype, style, and speculation, the truth is that the iPad is really just another tablet device. A really big PDA, where a touchscreen does what a laptop's keyboard used to do.

The iPad - contrary to the way most people thought about it - is not a tablet computer running the Apple operating system. It's more like a very big iPhone, running the iPhone operating system.

It feels as if ever since the iPhone was released, the Macintosh computer has become just another leverage point in this other operating system's marketing plan.

As Apple continues to release new styles of netbooks, laptops, and even desktops with untold movie-watching and game-playing capabilities, I wouldn't be surprised to see the iPhone operating system running on them - and the Macintosh eventually becoming a thing of the past.
