Stewart Butterfield has been at the forefront of two epochal turning points for tech. First, he was the co-founder of the photo sharing site Flickr, that was one of the defining brands of the so-called Web 2.0 and the world of user-generated content. Several years after that, he co-founded Slack, one of the big winners of the software-as-a-service wars, changing how people work and how companies operate. Now we're at another turning point for the tech industry. Layoffs have occurred across the space and AI is putting traditional business models into doubt. On this episode, we speak with Butterfield about his experiences and what he sees coming next for tech.
