The amount of writing that people do online is astonishing, and historically unprecedented.

Politicians or pundits can distort or cherry-pick climate science any way they want to try and gain temporary influence with the public. But any serious industrialist who's facing 'climate exposure' - as it's now called by money managers - cannot afford to engage in that sort of self-delusion.

Ambient awareness is the experience of knowing what's going on in the lives of other people - what they're thinking about, what they're doing, what they're looking at - by paying attention to the small stray status messages that people are putting online.

Plays are frequently infected with ideas that came from actors or even sound engineers. Some Shakespeare scholars wonder whether some of the Bard's lines came from onstage improvisations by actors.

Tip-of-the-tongue syndrome is when people almost remember something but need a computer, or someone else, to help them find it. The problem is, our brains have always been terrible at remembering details. They were like that way before the Internet came along.

The one complaint about the Internet that I wholeheartedly endorse is that most of these tools have been designed to peck at us like ducks: 'Hey, there's a new reply to your comment! Come look at it!'

The Internet lets thousands of total strangers collaborate to produce a truly hivelike result.

The things kids can do on screens can be really delightful - if they are age appropriate. But no, they shouldn't spend all their time on a screen; they should split up their time doing multiple, different things.

If you, or any public-spirited programmer, wanted to figure out what the software on your machine is really doing, tough luck. It's illegal to reverse engineer the source code of commercial software to find out how it works.

We're dumber and less cognitively nimble if we're not around other people - and, now, other machines.

Insurance firms have always carefully studied real-world data to figure out what, precisely, constitutes a risky activity.

There is something about the ability to externalize our thoughts and compare them with other people in a public way that is really transformative for the average person.

More than any other modern tool, computers are a total mystery to their users. Most people never open them up to fix them or to see how they work.

America has always had tinkerers, including just about any teenager who ever hot-rodded a Camaro.

Railing at scientists for massaging tree-ring statistics won't stop the globe from warming if the globe is actually, you know, warming.

A huge amount of our everyday thinking - powerful, creative, and resonant stuff - is done socially: talking to other people, arguing with them, relying on them to recall information for us.

The only reason we don't notice how absolutely interwoven our thinking processes have become with older technologies - pencils, paper, electric light, penicillin, fire - is that they're old, so we've ceased to notice their effects.

When you're an expert in a subject, you can retain new factoids on your favorite topic easily. This only works for the subjects you're truly passionate about, though. Baseball fans can reel off stats for their favorite players, then space out on their own birthday.

Novelists in particular love to rhapsodize about the glory of the solitary mind; this is natural, because their job requires them to sit in a room by themselves for years on end. But for most of the rest of us, we think and remember socially.

Personally, I'd love to see more social media firms develop business models that aren't reliant on advertising. If you're a social media firm selling ads, your goal is to get people to interrupt what they're doing all day long so they come and stare at your service as much as possible.

Transactive memory works best when you have a sense of how your partners' minds work - where they're strong, where they're weak, where their biases lie. I can judge that for people close to me. But it's harder with digital tools, particularly search engines.

The humanitarian developers behind World of Warcraft have also discovered a way to bribe gamers into turning off their computers and going outside. If you log off for a few days, your character will be more 'rested' when you resume playing, a mode that temporarily speeds up your leveling.

A textbook requires a consistent sense of style and a linear structure, hallmarks of a single authorial presence. An encyclopedia doesn't.

Why are online games so addictive? It's mostly the narcotic appeal of 'leveling.'

Software is now so complex - requiring so many gazillions of tiny files all over your computer - that most consumers don't want to bother to know what's really going on.
