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.

Advertising just keeps getting heavier and heavier and heavier. It doesn't have any natural limit, and we haven't found the place for the limit. And I think it's really important, therefore, that some of the revolts that are undergoing right now, you know, whether it's ad blockers or other things, are people trying to set some lines so that we say, you know, this far but no further. And this is where it ends.

I do think the best thing for companies like Google and Facebook, if they are afraid of this ethical trap of advertising, is they should start letting people pay who want to pay and avoid some of the advertising.

Google - and some of the other sites, YouTube and, you know - Google has an amazing search engine. The map product is incredible. So there's a sort of exchange when you put up with a bunch of ads. Facebook basically gives you access to your friends who, in theory, you had access to already. So sometimes I don't really understand the deal, but I guess it makes it slightly easier. So that's their contribution.

Socialization would be the most successful thing to bring mainstream audiences to online computers.

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

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.
