Rather than saying people aren't interested when things don't take off, you should take it on yourself to say, 'I'm not doing a great job of telling the story in a way that makes it interesting.'

The Google self and the Facebook self, in other words, are pretty different people. There’s a big difference between “you are what you click” and “you are what you share.

Try to throw a rock through a virtual storefront, and you just get an error.

The most serious political problem posed by filter bubbles is that they make it increasingly difficult to have a public argument.

But what’s troubling about this shift toward personalization is that it’s largely invisible to users and, as a result, out of our control. We are not even aware that we’re seeing increasingly divergent images of the Internet. The Internet may know who we are, but we don’t know who it thinks we are or how it’s using that information. Technology designed to give us more control over our lives is actually taking control away.

Partisans are more likely to consume news sources that confirm their ideological beliefs. People with more education are more likely to follow political news. Therefore, people with more education can actually become mis-educated.

Personalized filters play to the most compulsive parts of you, creating “compulsive media” to get you to click things more.

Our brains tread a tightrope between learning too much from the past and incorporating too much new information from the present. The ability to walk this line – to adjust to the demands of different environments and modalities – is one of human cognition’s most astonishing traits. Artificial intelligence has yet to come anywhere close.

Democracy requires citizens to see things from one another’s point of view, but instead were more and more enclosed in our own bubbles. Democracy requires a reliance on shared facts; instead were being offered parallel but separate universes.
