A race has broken out in Silicon Valley to create a breakthrough "brain-computer interface". Such a device would herald a new era of telepathy, and eventually, merging with artificial intelligence. It also brings with a hornet's nest of challenges. Who will control it? Will our thoughts be policed? Billions of dollars are being poured in to the technology that remains wrapped in secrecy. We talk to people on the front lines to figure out what is really going on. In this new eight-part series, the Sunday Times' technology correspondent Danny Fortson tells the story of the valley through surprising narratives and portraits of key players.  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.
