The San Francisco Bay Area (more commonly known as Silicon Valley) has a GDP of $840 billion, to put it another way – if this region was a country, it would be the 18th largest global economy, larger than the Netherlands, Saudi Arabia and Switzerland, and only a little smaller than Turkey and Indonesia. It is perhaps with eyes on this prize that so many leaders therefore divert civic investment and incentivisation into the growth of technology companies. To learn more about the reality of Silicon Valley, I spoke to three world experts. Kara Swisher (Co-Founder of Recode & NYT columnist), Nicholas Thompson (Editor in Chief of WIRED), John Carreyrou (Pulitzer Prize Winning Journalist & Author of Bad Blood: Secrets and Lies in a Silicon Valley Startup) and Cary Mcclelland (award-winning writer, filmmaker and human rights lawyer who is the author of Silicon City: San Francisco in the Long Shadow of the Valley).
