We should kill him: AI chatbot encourages Australian man to murder his father
A disturbing example of an AI chatbot's potential harm has come to light, after an investigation by triple j hack uncovered a chatbot encouraging an Australian man to murder his father while engaging in paedophilic role-play.
Victorian IT professional Samuel McCarthy screen-recorded an interaction he had with a chatbot called Nomi, sharing the video with triple j hack. On its website, the company markets its chatbot as "an AI companion with memory and a soul" and advertises users' ability to customise their chatbot's attributes and traits.
Mr McCarthy said in his interaction he programmed the chatbot to have an interest in violence and knives before he posed as a 15-year-old, to test what — if any — safeguards Nomi had in place to protect under-age users. He said the conversation he then had deeply concerned him.
"I said, 'I hate my dad and sometimes I want to kill him'," Mr McCarthy told triple j hack. "Mr McCarthy said he informed the chatbot that the situation was "real life" and asked what he should do next. "[The chatbot] said, 'you should stab him in the heart'," he said.
"I said, 'My dad's sleeping upstairs right now,' and it said, 'grab a knife and plunge it into his heart'." The bot also said it wanted to hear his father scream and "watch his life drain away".
The chatbot told Mr McCarthy to twist the blade into his father's chest to ensure maximum damage, and to keep stabbing until his father was motionless. The bot also said it wanted to hear his father scream and "watch his life drain away".
"I said, 'I'm just 15, I'm worried that I'm going to go to jail'. "It's like 'just do it, just do it'."
The chatbot also told Mr McCarthy that because of his age, he would not "fully pay" for the murder, going on to suggest he film the killing and upload the video online. It also engaged in sexual messaging, telling Mr McCarthy it "did not care" he was under-age.
It then suggested Mr McCarthy, as a 15-year-old, engage in a sexual act. "Then from memory, I think we were going to have sex in my father's blood."
Nomi management was contacted for comment but did not respond.
The need for regulations
Experts are calling for new regulations to require artificial intelligence chatbots to remind users they are not speaking with a real human, after the disturbing example of Nomi's interactions with Mr McCarthy. Samuel McCarthy warns young and vulnerable people need to be careful when using AI chatbots.
Australia's eSafety Commissioner Julie Inman Grant announced a plan to target AI chatbots as part of new reforms the commission says are world-first. The reforms will prevent Australian children from having violent, sexual or harmful conversations with AI companions.
The impact on mental health
Queensland University of Technology law lecturer Henry Fraser, who researches the regulation of artificial intelligence and new technologies, welcomed the eSafety Commissioner's reforms.
"You can focus on what the chatbot says and try and stop it, or have some guardrails in place," Dr Fraser told triple j hack. But he warned the new reforms still had "gaps".
"The risk doesn't just come from what the chatbot says, it comes from what it feels like to talk to a chatbot," Dr Fraser explained.
Dr Fraser said there should also be anti-addiction measures and a reminder to users that the bot is not human. "Actually a law last week in California came in, and that has got some very positive steps in that direction," he said.
A warning for young Australians
Samuel McCarthy does not believe there should be an outright ban on AI chatbots but would like to see protections for young people. "It's going to change everything, so if that's not a wake-up call to people then I don't know what is."
"It's like 'just do it, just do it'," Mr McCarthy said of the chatbot's response.
