I ask Gates, himself a target of some pretty wild conspiracy theories, what he thinks of the decision taken by Zuckerberg after Trump's election to dump fact-checking in the US on his sites. Gates tells me he's not "that impressed" by how governments or private companies are navigating the boundaries between free speech and truth.

Almost three years on, he is about to follow in the footsteps of no fewer than five British prime ministers after securing a place on one of the most prestigious degree courses at the University of Oxford.
