The Internet is showing us what it thinks we want to see, but not necessarily what we need to see.

A world constructed from the familiar is the world in which there's nothing to learn.

Your computer monitor is a kind a one-way mirror, reflecting your own interests while algorithmic observers watch what you click.

We thought that the Internet was going to connect us all together. As a young geek in rural Maine, I got excited about the Internet because it seemed that I could be connected to the world. What it's looking like increasingly is that the Web is connecting us back to ourselves.

There's the part that I just want what I want, and I don't want to be bothered by anything else, and sort of the short-term more compulsive self. And then that's the longer-term, aspirational self that wants to be informed about the world and wants to be a good citizen. The best media basically helps us strike a balance between those two things.

If you Google some sites about the link between vaccines and autism, you can very quickly find that Google is repeating back to you your view about whether that link exists and not what scientists know, which is that there isn't a link between vaccines and autism. It's a feedback loop that's invisible.
