When you decide to like something, I mean, you may feel you're sort of innocently putting out your preferences, but actually you're delivering something of enormous value, which is indicating that, you know, you'd essentially like to be advertised to by this company.

The Holy Grail of advertising has always been advertisement that people want to watch, which occasionally happens. You know, the Super Bowl, people sit there and watch the advertisements. Some print advertising is very beautiful.

Let's say you're someone's phone, and you notice that your owner is drinking coffee at certain times of the day, just very subtly indicating where the local coffee shop is which happens to have paid, you know, whoever makes your phone at the right moment. I think we're in a future where frankly we are possibly facing little tiny bits of manipulation in all of our waking hours, if we don't have that already.

I think that's been really the key, the idea of trying to harness social capital for selling purposes. That we've let this happen so easily without clearly getting something in exchange is kind of amazing to me.

Facebook, when it began, like Google, was very resistant to advertising. They knew, like all - Mark Zuckerberg, like all good engineers, knew that advertising makes the product worse. But, you know, over time, they've been forced to increase the advertising load more and more and more. And the way they advertise is they - it's subtle but they know everything, you know, about everybody on the site.

When you think about normal advertising, it's just like, hey, here's a car and, you know, we don't know if you're looking for a car or not. So Google promised that mental state, and then were able to prove that delivering the message at the exact right moment would make someone click on something. So they pioneered the idea that advertising could be profitable on the internet, that a specific, very micromental state could be targeted. And they established the primacy of the click, which has haunted us ever since.

There's a problem which is when you're trapped in your own identity and everything is really you, then you feel less freedom to sort of explore who you want to be. So I think it's kind of something we're stuck with as long as humans are the way we are.
