> it's unfortunate that so many smart people use their intelligence to enable this kind of gross technology We live in a capitalist society. It just so happens that this "gross technology" makes advertising insanely profitable for millions of companies (mine included), which makes FB billions, so they'll happily pay really smart people millions to build it. And those smart people will happily accept millions to solve those hard problems. It's just business. If you can figure out how to better align individual and corporate incentives with making the world a better place, we're all ears.
