Episode Details

Slack was supposed to liberate knowledge workers from email hell. Instead, it gave us two inboxes to check and higher stress levels. But while it failed at human communication, the same architecture—channels, subscriptions, bot APIs—turns out to be the perfect notification layer for AI agents. We trace how Slack's structural failures for people became its accidental strengths for machine-to-human communication, and what that means for the future of how AI talks to us.
