I set up a company, an algorithmic auditing company myself. I have no clients.

Every system using data separates humanity into winners and losers.

There are lots of different ways that algorithms can go wrong, and what we have now is a system in which we assume because it's shiny new technology with a mathematical aura that it's perfect and it doesn't require further vetting. Of course, we never have that assumption with other kinds of technology.

We've learned our lesson with finance because they made a huge goddamn explosion that almost shut down the world. But the thing I realized is that there might never be an explosion on the scale of the financial crisis happening with big data.

You'll never be able to really measure anything, right? Including teachers.

The public trusts big data way too much.

There might never be that moment when everyone says, "Oh my God, big data is awful."
