Soon enough, nobody will remember life before the Internet. What does this unavoidable fact mean? Mark interviews Michael Harris, author of The End of Absence.

For future generations, it won't mean anything very obvious. They will be so immersed in online life that questions about the Internet's basic purpose or meaning will vanish.

But those of us who have lived both with and without the crowded connectivity of online life have a rare opportunity. We can still recognize the difference between Before and After. We catch ourselves idly reaching for our phones at the bus stop. Or we notice how, mid-conversation, a fumbling friend dives into the perfect recall of Google.

In this eloquent and thought-provoking book, Michael Harris argues that amid all the changes we're experiencing, the most interesting is the one that future generations will find hardest to grasp. That is the end of absence—the loss of lack. The daydreaming silences in our lives are filled; the burning solitudes are extinguished. There's no true "free time" when you carry a smartphone. Today's rarest commodity is the chance to be alone with your own thoughts.

To understand our predicament, and what we should do about it, Harris explores this "loss of lack" in chapters devoted to every corner of our lives, from sex and commerce to memory and attention span. His book is a kind of witness for the "straddle generation"—a burst of empathy for those of us who suspect that our technologies use us as much as we use them.

By placing our situation in a rich historical context, Harris helps us remember which parts of that earlier world we don't want to lose forever. He urges us to look up—even briefly—from our screens. To remain awake to what came before. To again take pleasure in absence.

The end of absence is enigmatic; to talk about it we need new words.

Overspire
The experience of too much inspiration, resulting in no further gains in creativity.

Over the weekend I watched a dozen TED Talks in a row and got this vaguely overspired feeling.

Techapropism

The appropriation of computer terminology to describe real-life experiences. Nick walked into the party and muttered to his girlfriend, "None of your preferred networks are available."

Straddle Generation
Neither Digital Natives nor wholly Digital Immigrants; they were born in the 1980s and will be the last people to remember life without the Internet. After she got text-dumped, Stacey was determined to only date Straddle Gen guys. "They're so Romantic!"

Wagging the Crowd
Purposeful manipulation of ratings on crowd-based voting systems like Yelp. Jim's restaurant was failing so he hired a click farm in India to wag the crowd.

Condition Creep
The degree to which each generation loosens their privacy settings and becomes more at ease with purveyors of big data. Typified by the automatic acceptance of unread "terms and conditions." Jonah's dad noted a bit of condition creep when he saw the links to homemade porn on his son's Twitter feed.

Lens Amnesia
The experience of forgetting one is viewing reality through a particular technological lens. George was shocked to discover that Rebecca had blurred out an unfortunate mole constellation in her profile photos.

Annotation Dependence
The contention that everything ought to be gilded in supporting text. Looking up from the Google Map, Brady was discomfited to find himself in a baffling network of poorly labeled streets.

Super-Sanction
The act of granting worth or authenticity to something by upping its digital presence. For example, broadcasting images of the food one is about to consume. (Related to an Englightenment bias that presumes making information available is akin to making it valuable.) Before tucking in, the men gave their steaks a super-sanction on Instagram.

Unicorn
A person with no online presence who thus boasts a ghostly or mythical quality when he/she shows up in person. Clay's Facebook sabbatical leant him a unicorn quality and upped his cachet at grad parties.

Cloud Faith
The assumption that algorithms and crowd-sourced data will invariably derive more meaningful outcomes. Long ago Derek had decided to choose movies based on cloud faith.

Betaphobia
The fear of missing out on the first wave of a new technology. Carlos got a serious hit of betaphobia when he saw her robotic dog ambling over to meet them.

Slownet
Programs that allow users to limit their access to online content. Mariko kept on getting sucked into Katy Perry videos so she jacked up her Slownet settings.

Flashcard Confessional
A genre of video in which the creator—typically a teenaged female—confesses private trauma through a series of flashcards bearing Sharpie text. The whole school saw her flashcard confessional so now she was a loser and an attention whore, too.

Staccato Love
A relationship maintained by short and detached bursts of intensely affectionate messaging. Just one of Christina's staccato love messages could keep him going for a week: OMG U R soooooooooo cute!!! ;-)

MiniGen
A distinct group of people born within five years of each other. At the party all the kids a minigen younger than me were obsessed with memes I'd never heard of.

Megapproval
The act of boosting something online in as many arenas as possible, often through passive "like" systems on Facebook, etc. It wasn't enough to just buy the new Death Cab for Cutie album, Tomer opened his laptop and started megapproving it.

Deja-Zeitgeist
The sense that all content is now merely a revision of content from earlier decades.

Why didn't I think of that Archie satire?

Derivaphilia
The love of derivative content over original content. Did you see the Dr. Who t-shirt Liam made? Amazing.

Tandem Talk
The act of cruising Google in tandem with a phone conversation in order to source info or anecdotes and bolster one's own ideas. I thought Derek knew a lot about sea slugs but it turned out he was just tandem talking.

Unmember
To offload a memory from brain to computer. It was such a relief to unmember Dai's boyfriend's name.

Compound Distraction
The experience of one person's distraction compounding another's. Julie kept texting while I was talking about my dog, so I started texting, too. Exists in two varietals: Limited Compound Distraction refers to a moment of positive feedback distraction (i.e. Bailey kept texting while I was telling him about the exam so I started Tweeting about it instead) whereas Assumed Compound Distraction refers to a pre-determined atmosphere of distraction wherein sustained, meaningful interaction feels awkward and unwelcome. (i.e. Harry and Bryce mumbled to each other about Iran while scrolling through the news on their respective phones)

Phone Dodge
The act of compulsively checking one's phone in an awkward situation. Susan's friends weren't at the bar yet so she pulled a phone dodge and became fascinated by her Pinterest feed.

Micro Death
The state of waiting for a technology to complete an internal process, of being put on hold by a computer. Julie's mouth dropped open an inch each time her tablet loaded a page.

Phone Leash
The limit from home that one can travel without a phone before anxiety kicks in. He got two blocks down the street before his phone leash whipped him around.

Disconnection Rage
A sudden and unaccountably fierce meltdown brought on by five minutes of lost access to the Internet. Susan bawled at the harried barista when the café's wifi signal faltered.

Going Walden
The often ill-conceived decision to live without connective technologies for a period of time in order to cleanse the spirit. "While we're in Bali," said Harry, "what if we went totally Walden?"

Tech Dilation
An increased commitment to visual information, as encouraged by certain technologies. Tom's eyes were bugged out with tech dilation after burrowing into his phone for twenty minutes.

Phone Burrow
The act of becoming dead to the world while pouring all attention into a phone. (Often more obvious in public spaces.) She froze in the intersection, dove into full phone burrow, and let her umbrella drop to the pavement.
