Social media is an existential threat to our idea of democracy

John Naughton in The Guardian:

At last, we’re getting somewhere. Two years after Brexit and the election of Donald Trump, we’re finally beginning to understand the nature and extent of Russian interference in the democratic processes of two western democracies. The headlines are: the interference was much greater than what was belatedly discovered and/or admitted by the social media companies; it was more imaginative, ingenious and effective than we had previously supposed; and it’s still going on.

We know this because the US Senate select committee on intelligencecommissioned major investigations by two independent teams. One involved New Knowledge, a US cybersecurity firm, plus researchers from Columbia University in New York and a mysterious outfit called Canfield Research. The other was a team comprising the Oxford Internet Institute’s “Computational Propaganda” project and Graphika, a company specialising in analysing social media.

We have been warned.
