I think big data companies only like good news. So I think they're just hoping that they don't get sued, essentially.

There's less of a connection for a lot of people between the technical decisions we make and the ethical ramifications we are responsible for.

The disconnect I was experiencing was that people hated Wall Street, but they loved tech.

That's what we do when we work in Silicon Valley tech startups: We think about who's going to benefit from this. That's almost the only thing we think about.

The training one receives when one becomes a technician, like a data scientist - we get trained in mathematics or computer science or statistics - is entirely separated from a discussion of ethics.

An insurance company might say, "Tell us more about yourself so your premiums can go down." When they say that, they're addressing the winners, not the losers.

When I think about whether I want to take a job, I don't just think about whether it's technically interesting, although I do consider that. I also consider the question of whether it's good for the world.
