Long conversations

A “long conversation” is a new format for a conference. Two speakers begin a conversation on stage. After 15 minutes one of the two speakers is replaced by a new speaker and the conversation continues, and every 15 minutes for the next 8 hours a speaker is swapped out. (Each speaker converses for 30 minutes.) The day is engaging, unpredictable, passionate, diverse, informative, and entertaining. It’s a format invented by Long Now Foundation that is worth stealing. For an example, here are highlights from a long conversation held at the Smithsonian. — KK
