Facebook faces more criticism for its handling of misinformation around the US election, this time by members of Joe Biden's team. Could the next US president lead a crackdown on the social media giant? We speak to Siva Vaidhyanathan, professor of media studies at the University of Virginia and author of Antisocial Media: How Facebook Disconnects Us and Undermines Democracy. Also on the show: Apple launches a range of new laptops, but it's the chips inside them that are causing a stir. We ask Raspberry Pi creator Eben Upton if it's the end of the road for endlessly faster processors. Plus Hyperloop makes some headlines with a high-speed test in the desert, but is it really going to revolutionise transport systems around the world?
