That the chatbot tells them, to quote one email, that they’ve ‘cracked the code’. That they’re ‘the only one that could’.”OpenAI considered alerting Canadian police about school shooting suspect months agoRead moreThe chatbots have been designed that way, Walsh said.“They’re designed to be sycophantic. They’re designed to confirm what the user says. And they’re designed to draw the user in. They always end with an open question, prompting you to continue the conversation and buy more tokens.”He said it was not in the interests of the companies responsible for the chatbots to tell users to log off instead.“There’s no reason that they couldn’t be designed that way. Except the careless people in Silicon Valley would make less money if they were.”OpenAI has claimed a GPT-5 update reduced the number of undesirable behaviours from its product and improved user safety.Walsh also expressed anger over the “large-scale theft” of creative works being used to train AI, and over the summaries for news articles in search taking away traffic from news sites.“Legally you can’t call it fair use when you’re competing with the owner of the IP,” he said.“I refuse to accept an AI revolution that enriches founders in Silicon Valley by impoverishing Australian artists, writers and musicians.”Walsh took aim at companies he said were disregarding laws, particularly around scams.In November, Reuters reported that Meta’s internal documents from late 2024 stated that Meta was projected to earn about 10% of its overall annual revenue – about $16bn – from illicit advertising that year.Meta responded saying it had reduced scam ads by 58% in the past 18 months.Walsh said AI is being used to generate these scam ads, and Meta allowed advertisers to use AI to manage these ad campaigns, while AI decides which ads people see.View image in fullscreenUniversity of NSW professor Toby Walsh.

But another generation of young Australians has now been sacrificed for the profits of big tech’.”Explore more on these topicsTechnologyAI (artificial intelligence)BusinessMetanewsShareReuse this content
