We have just decided we have to have everything for free. And I think we're starting to pay for it in terms of our mental states.

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.

Hitler had this understanding that you speak to people's deepest, darkest emotions and give them voice that can be incredibly effective.

Movies you pay for - well, sometimes they throw some ads at the beginning now - but generally you pay for ads. And that business model - actually, much more ancient, paying for stuff - is much more straightforward in terms of the incentives of the people who are then giving you the stuff.

Advertising always corrupts the goal of the search engine, which is to try to give you the most important stuff, not the stuff someone paid there to be there.

Nothing, save the hangman's noose, concentrates the mind like piles of cash.

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.
