Trolling is an ancient problem. It's been around as long as there has been media.

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.

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.

All business models have something challenging about them, but the problem with the attention merchant business model they have is they need to keep increasing the amount of ads they deliver to people and therefore make their product worse.

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.

I'm afraid when too many people know too much about you, it actually makes us all a lot more boring because you're afraid to express yourself.

You have to think back to the '90s. The computer was this terrible-looking thing that was trying to compete with the television. And it was this idea of email and chat rooms and this kind of stuff that first people - got people there.
