The tide of public opinion has turned against the big tech firms. How serious of a threat are these companies to democracy? Are they having a malign impact on our economies? And if they are, can people and governments stand up to Silicon Valley?

The RSA's director of economy, Asheem Singh, speaks to Roger McNamee, an early investor in Facebook – now turned vocal critic – and author of ‘Zucked: Waking Up to the Facebook Catastrophe’.

Plus: Ian Leslie and Matthew Taylor dish out some free advice to the tech giants. You're welcome, Mr. Zuckerberg.
