Australia's spy chief warns AI will accelerate online radicalisation

The head of Australia's peak intelligence agency has warned that people like the Christchurch terrorist are being radicalised on social media, and artificial intelligence is likely to make it much worse. The director general of the Australian Security Intelligence Organisation (Asio), Mike Burgess, told a social media summit in Adelaide on Friday that social media is "both a goldmine and a cesspit" that creates communities and divides them, and the internet was "the world's most potent incubator of extremism". He said people were embracing anti-authority ideologies, conspiracy theories and diverse grievances, and while social media was not the sole driver, he said Asio considered it a "significant driver". "Social media allows extremist ideologies, conspiracies, dis- and misinformation to be shared at an unprecedented scale and speed," he said. He said radicalisation can now take days and weeks rather than months and years as it previously did, with the most likely perpetrator of a terrorist attack being a lone actor.
