We've never thought too deeply about the roles things like forgetting or partisanship or inefficiency or ambiguity or hypocrisy play in our political or social life. It's been impossible to get rid of them, so we took them for granted, and we kind of thought, naively, that they're always the enemy.

Faster roads are not always safer roads - and virtually all societies, democratic or authoritarian, prefer safety over speed, even if many of their citizens enjoy fast driving.

There is no doubt that the Internet brims with spamming, scamming and identity fraud. Having someone wipe out your hard drive or bank account has never been easier, and the tools for committing electronic mischief on your enemies are cheap and widely accessible.

There is this absurd assumption that the revitalisation of the public sphere is always a good thing. I think people tend to confuse 'civic' and 'civil,' and they believe that everything that is done by citizens is necessarily a good thing because you build a network, an association.

Many of us were a little to early to assume that the most logical uses of the internet in authoritarian states would be to empower people. And to force them towards participation in politics. If you look at most authoritarian states, they are very grim places to live in. The only good thing about it is fast internet. That's the only way you can find some meaning in an otherwise very dark and gloomy life.

In addition to their 'do no evil' motto, Googlers have always been guided by another, much less explicit philosophy: 'computational arrogance.'

Search without Google is like social networking without Facebook: unimaginable.
