The power of talk, and mythical startup valuations

Sherry Turkle, clinical psychologist and MIT professor, stops by to speak with host Shannon Bond on how our addiction to our tech devices has stunted our ability to converse with friends, family and colleagues - the topic of her new book "Reclaiming Conversation: The Power of Talk in a Digital Age". Then, FT journalists break down the differences in valuing public and private tech companies, especially the so-called unicorn startups. Finally, a preview of the latest Alphachatterbox episode featuring development economist Esther Duflo.
