Greg Epstein is the humanist chaplain at Harvard and MIT, and he has spent the past several years examining the rising power of tech through the lens of faith.

On POLITICO Tech, Epstein joins host Steven Overly to talk about his new book, “Tech Agnostic,” and why he sees the need for a tech “reformation.” Learn more about your ad choices.
