The city by the bay is ground zero of the tech revolution, but it has taken a dystopic turn. We dive inside San Francisco, where there are more billionaires per square foot than anywhere on the planet, but also more injection drug user than high school students. Families are fleeing; homelessness is soaring. We examine what the city can tell us about our techno-centric present - and the future.   In this new eight-part series, the Sunday Times' technology correspondent Danny Fortson tells the story of the valley through portraits of key players through its short history.  DIVE DEEPER - longform interviews on Danny's sister podcast, Danny In The Valley - read Danny's longform commentary on the series at thetimes.co.uk Produced by Cheeka Eyers at Rethink Audio for Wireless Studios and The Sunday Times.
