We are living in a time of extreme self surveillance. We carry with us devices that capture our every location, info about our health, and data about our private lives.

Digital technology exposes everyone, everywhere, all at once, and we have few laws to regulate it.

No other phenomenon has shaped human history as decisively as capitalism. It structures how we live and work, how we think about ourselves and others, how we organize our politics.
