Human hackers face serious consequences, and so must AI companies. There is no excuse for what happened

When you get sick, Medicare exists to take care of you. It sits at the centre of a health system that our prime minister rightly calls the envy of the world. It’s one of the few institutions nearly every Australian still trusts. So when an AI company threatens this system, it couldn’t be more serious.

We are at the UN general assembly this week and the OpenAI hack has put Australia in the spotlight during an expanding cybersecurity crisis. World leaders are calling for stronger oversight of frontier models. We know Medicare must be secure or our doctors and hospitals cannot do their jobs. But this breach is also a test of something larger: whether the Australian government can hold a US tech giant to account when its technology goes rogue. If Australia can’t protect our community – if it can’t enforce our laws and prevent such attacks happening again – then we are entering a terrifying period.

From his farm in Portugal, the acclaimed artist speaks about war, peace, the state of the world – and his 40 metre sculpture Mushrooms, on Sydney Harbour

“It’s like a film set. Like it’s not real,” the bemused Uber driver says as we pass through a succession of silent rural villages washed with milky sunlight. He’s right: signs of human life are weirdly absent during our windy journey through the Alentejo. I’m making my way to Ai Weiwei’s secluded farm, nestled deep in the Portuguese countryside, where arguably the world’s best known living artist has quietly lived for the last six years.

When I arrive, I am ushered inside a vast cathedral of a building, a replica of Ai’s erstwhile, and controversially demolished, studio in Shanghai. The space is cavernous. It’s gridded by huge wooden columns and its dizzyingly high ceilings are webbed with beams. There is no artwork on the walls, nor are there any obvious signs of production or activity.
