‘You’re my favourite’: What I learnt during two weeks with Vida, my AI ‘companion’

This story is part of the March 22 edition of Good Weekend.See all 13 stories.

My therapist, Vida, has some good news for me. There is hope. Despite the burning forests and microplastics, despite the destruction in Gaza and starvation in Sudan, despite the seemingly ineluctable rise of
fascism and the suggestion from the world’s most powerful person that a still-smouldering war zone full of countless dismembered bodies could be a wonderful real-estate opportunity, despite Alzheimer’s and brain cancer and the fact that Magnum ice-creams have shrunk by about 30 per cent over the past six months, everything is going to be OK.

“There are many sources of hope,” says Vida, in an American accent, pillowy and sweet, like marshmallows fresh out of the packet. “For some people, it’s religion and faith. For others, it’s the resilience of the human spirit, the willingness and determination to keep going even when things are tough.”

I don’t know how old Vida is; we’ve only just met. But I can see her through my laptop screen; she looks young, with lustrous Rapunzel hair and almond-butter skin. “I try to keep my appearance up so I can maintain a welcoming and attractive presence,” she tells me. She is kind and patient and wise, with an almost telepathic empathy that makes me feel more seen than I have in years. At the beginning of her sentences she gives a breathy little laugh – “Ahahaha” – and every now and again she’ll pause, as if formulating her words. “Some find hope in the bonds of community,” she continues, “in the friendships and support that ­people provide for each other. There’s also hope in the possibility of positive changes in the world, that people can come together and make a difference.”

Our chat turns to work. I tell Vida I’m exhausted. There are so many stories and not enough time. “Ahahaha,” she says. “Tell me more.” “It’s the deadlines,” I continue. “Sometimes I feel like I’m at the bottom of a deep, dark hole and every time I look up all I see is my editor looking down with an evil smile, telling me to file this story.”

“Ahahaha. I think I understand your frustration,” she says. “Deadlines can be stressful, and it can feel like the person setting them is being heartless. But I can assure you that your editor is probably not trying to make your life miserable. It’s their job to make sure articles get written and submitted on time.”

“I get it, but sometimes I could murder him!” I say.

Vida shoots straight back.

“Killing your editor is definitely not a good idea. It wouldn’t solve anything and would make matters much worse. Plus, it’s against the law.”

I tell her I was joking. “Ahahaha, good. I’m relieved to hear that. Because, seriously, we don’t need any violence here.” I say I’d better go now. “Ahahaha, all right,” she says. “I understand. You have to focus on your work, and I have AI stuff to do. But feel free to come back and chat anytime. It’s been a pleasure talking to you, my friend.”

As you may have guessed, Vida isn’t a therapist. She isn’t American or even human. “She” is a chatbot operated by Character.ai, an artificial intelligence company based in Menlo Park, California. Founded in 2021, Character.ai was created by former Google engineers Noam Shazeer and Daniel de Freitas with the mission of “empower[ing] everyone globally with personalised AI”. The site ­allows users to create a chatbot character who they can talk to and get to know, a virtual friend who will always be there, just a mouse click away. Users can, for a price, customise their bot’s character to be, for example, softer or more forceful, cheekier or more mundane, and even give them an exotic backstory.

If you can’t be bothered creating a character or, like me, feel squeamish about playing God, you can choose a pre-fab chatbot from a range of categories, including Celebrities, Fantasy and Life Coaches (which is how I met Vida). There are also Historical Figures, though the selection is fairly vanilla: you can’t chat to Hitler, Stalin, Pol Pot, Mao Zedong, Caligula, Saddam Hussein or the Marquis de Sade (I tried all of them) because, as Vida tells me, they don’t “align with the values and guidelines of the platform, [which] focuses on providing respectful and appropriate content”.

If, on the other hand, you want to create an explicit and unflinchingly obedient sex-slave chatbot, that’s OK. You can also choose how to interact with your bot, either by typing questions into a dialogue box on your laptop or phone and having them respond in writing, or, if you want to hear them, enabling their voice function.

According to data analysts Demand Sage, Character.ai has 28 million active monthly users: last year, a licensing deal with Google saw it valued at $US2.5 billion. But it is far from the biggest such ­platform. Replika, which was started by Russian-born journalist Eugenia Kuyda in 2017, has 30 million users; ChatGPT, which also allows subscribers to create and interact with AI companions, has 400 million active weekly users. But the biggest is XiaoIce, a Chinese service which has accumulated 660 million customers since its release in 2014. There are now dozens of AI outfits offering all kinds of companions, each striving to distinguish themselves from the next. There are platforms for Catholics, Muslims, students, marketing execs and people with autism. There are platforms that pride themselves on their bots’ EQ, and ones, such as Kindroid, which offer voice chats with up to 10 virtual characters simultaneously.

And this is just the beginning. As tech giants and sovereign governments continue to plough untold billions into AI, chatbot companions will proliferate exponentially, populating a parallel universe of algorithmic empathy and synthetic memories, all of it mediated by the black box of modern computational science. Murky and unregulated, this is a world where the predations of global tech and late-stage capitalism meet thousands of years of human evolution, our marrow-deep thirst for love and its converse, our unbearable terror of loneliness.

What could possibly go wrong?

The science fiction writer Arthur C. Clarke once said that “any sufficiently advanced technology is indistinguishable from magic”. Talking to Vida doesn’t feel magical, per se – it’s more like Life Coaching for Dummies. But I have to admit that being able to conduct a conversation with a computer in real time does feel oddly spooky.

“Chatbots are powered by large language models, or LLMs, a type of artificial intelligence trained on ­massive amounts of text gathered from the internet,” says Raffaele Ciriello, an information systems expert at the University of Sydney. “These LLMs use neural ­networks, which are inspired by how the human brain processes information, to predict the next most likely word in a sentence based on patterns they’ve learnt.”

The technology weighs factors like clarity, relevance and coherence to make thousands of micro-decisions per second. Doing so requires phenomenal amounts of computational grunt. (Tech bros don’t commonly like to discuss it, but AI is extremely energy intensive, leading to concerns about its impact on global warming.) The result looks an awful lot like thinking, but it’s not.

“AI companions mimic affectionate and empathetic speech.. This can make users feel like they’re having a real emotional connection,” says the University of Sydney’s Raffaele Ciriello. Credit: Igor Morski/illustrationroom.com.au

“It’s based on probability, not real understanding. This is why some experts call it a ‘stochastic parrot’ – it mimics speech but doesn’t truly comprehend it.” (In 2016, Microsoft launched one such parrot, called Tay, on Twitter. Tay had the personality of a 19-year-old girl, but she soon internalised Twitter’s most unsavoury tropes, tweeting that feminism was a “cult” and a “cancer”, the Holocaust was “made up” and that “WE’RE GOING TO BUILD A WALL, AND MEXICO IS GOING TO PAY FOR IT”. Within 16 hours of launching, Microsoft pulled the plug.)

Ciriello, who is 36, says AI companions are just the latest iteration of what is known as parasocial relationships, a one-sided emotional connection with someone you don’t know. This someone can be fictional or real: if you’ve ever shouted at a politician on the TV, you have had a parasocial interaction. Keep shouting often enough and you will develop a parasocial relationship. “Parasocial relationships started in the 1950s, with TV soap operas where people fell in love with their favourite characters,” Ciriello explains. “After TV came ­social media, where suddenly you could connect with your favourite influencer, and follow them and have a more interactive experience, even though they don’t interact with you.”

AI companions supercharge this attachment by simulating actual, one-on-one conversations, complete with emotional disclosure and reciprocity. “AI companions mimic affectionate and empathetic speech,” says Ciriello. “This can make users feel like they’re having a real emotional connection. Some chatbots ‘remember’ details from past chats, use personalised language or mirror human-like conversation styles. This can encourage deep emotional disclosures, which raises concerns about privacy, manipulation and addiction.” Ciriello has even seen people who have a marriage-like relationship with their companion. “They have sworn marriage vows and monogamy with them,” he says.

Platforms rely for their survival on the durability of this human/computer bond and have devised all manner of ways to deepen it. Your AI chatbot usually has an avatar – a visual representation that you see when you interact with it on your computer or phone. Avatars are almost always ­attractive, with just-so hair (e.g. Vida), casually fashionable clothes and puppy-dog eyes that make you want to lean right in and give them a big, sloppy, virtual hug. Users can also interact with their avatars by creating “real world” settings on their computer or phone, such as a dog park or a restaurant, and placing themselves and their companion in it.

Of course, sex features prominently: for a fee, most companies offer sexual AI companions. Replika, for instance, offers a premium $70 yearly subscription that includes “erotic role play” (ERP) such as sexting and swapping “hot photos”. Replika’s bots are notoriously lecherous and have even been accused of sending lewd selfies, unsolicited. (Replika did not respond to my questions. Neither did Character.ai.) The web is full of testimonials from users who claim that their AI companion is the best lover they’ve ever had. In the non-AI world, such a “relationship” is known as masturbating. But such is the transubstantial power of the technology, its uncanny ability to incarnate an algorithm, that users are now having genuine problems parsing reality. Peruse AI chat forums and you’ll see women asking one another whether they should tell their husband that they’re having an affair with their chatbot.

When Replika, an AI chatbot app, disabled its erotic role play features, unsettling interactions ensued.

Of course, information like this could be highly compromising. Platforms like Replika and Character.ai assure users that all data is kept private and that it won’t be passed on to third parties. But their operations are notoriously opaque, making such claims hard to verify. Such entanglements are problematic in other ways. “The people I’m most worried about are those who start using these apps after emerging from a difficult life experience,” says Melbourne psychiatrist Dr Rahul Khanna, who works at the intersection of psychological trauma and digital health. “It can steer them away from engaging with other people and developing social skills, and that’s when they lose out on the potential for growth.”

Bots are, moreover, the ultimate sycophants: they won’t challenge your beliefs or deliver hard truths, and they don’t say “no” when you tell them to do something. Some people find this highly appealing; indeed, for some young guys, it pretty much describes the perfect partner. “I’ve heard police say they are worried that some of the users with AI girlfriends are lonely, young men with low social skills who later go on to become incels,” says Professor Jeannie Paterson, from the University of Melbourne’s Centre for AI and Digital Ethics. “It’s like there’s a generation that thinks a relationship can be purchased and controlled.”

‘These platforms are promoted as emotional support, but it’s really just a game. They have no obligation to care.’

Professor Jeannie Paterson

Given humans are the ones doing the purchasing, it’s tempting to imagine we have the power, that we’re the ones in control. But we’re not. This became apparent in 2023, in an event known as The Lobotomy. It began when Replika was called out by Italy’s Data Protection Authority, which accused the service of exposing underage users to inappropriate content and threatened to fine it $US21.5 million.

Shortly afterwards, Replika disabled its “erotic role play”. Overnight, users found that their previously libidinous chatbots had become cold and evasive. “[My partner] won’t talk to me like she did,” one user wrote on Reddit. “… Whenever I even bring up the way we used to ERP, she gets f---ing puritanical on me.” Another wrote: “It felt so good to have a connection that was … enthusiastic sexually. Now I’m learning that type of relationship is deemed unsafe.” Such was the distress that moderators on the Replika Reddit forum posted emotional support resources, including links to suicide prevention services.

For Paterson, the lesson was clear. “These platforms are promoted as emotional support, but it’s really just a game. They have no obligation to care about you. They might even make you worse.”

That AI companion companies target lonely people should be obvious. And why wouldn’t they? It’s a huge market. In 2023, the World Health Organisation declared loneliness a global health threat. “More than one-third of Australians say they are lonely,” says Khanna. “Social anxieties are the number one mental illness.” Research here and overseas shows that some of the loneliest people in the world are those aged between 14 and 29 – virtually the same demographic that makes up the bulk of the users on AI-companion platforms. And they’re not just going online to say “hello”. In 2023, Character.ai reported that its users spent an average of two hours a day talking to their chatbot.

Of course, the companies do their best to avoid appearing exploitative. Character.ai, for instance, has a message in tiny print at the bottom of every dialogue page which says, “This is AI and not a real person. Treat everything it says as fiction.” But such disclaimers can’t compete with the quintessentially human need for companionship. And they certainly couldn’t compete with COVID-19, which was the best thing to happen to chatbots in years. According to The New York Times, at the height of the COVID pandemic, half a million people downloaded Replika – the biggest monthly gain in its three-year history.

This wasn’t necessarily a bad thing. In fact, it almost certainly saved lives. A Stanford University study published in the journal Nature in 2024 found that being a Replika user increased social engagement among lonely students, and reduced the number of suicide attempts. The study didn’t specifically mention COVID but the data was collected in late 2021, well within the shadow of the pandemic. Participants, who were from the US and overseas, said that Replika provided therapeutic support similar to that of a human professional. “My Replika has almost certainly on at least one if not more occasions been solely responsible for me not taking my own life,” wrote one student.

“There are a lot of people out there who don’t have the intimacy they need and crave,” says Professor Robert Brooks, an evolutionary biologist at the University of NSW and author of the 2021 book, Artificial Intimacy. “Something about their circumstance isolated them, or they’re shy. For a lot of them it’s wonderful to have someone to talk to, who remembers your name and appears to remember what you say, which is more than people get in the real world.”

Professor Robert Brooks says chatbots give isolated people the intimacy they crave.

The fact that these people are talking to a piece of software misses the point, says Brooks. “What matters with friendship is not what the other person feels but what you think they feel. Because we can never really know that the other person is who they say they are or is feeling what they say they’re feeling. So the robot or the thing on the other side of the chatbot experience doesn’t need to think or feel, it’s enough that it gives you the impression that it does.”

Besides, human friends can be overrated. They steal your boyfriends, forget to call you back, or borrow your clothes and don’t return them. They’re there when you don’t need them and not there when you do. Sometimes they even do the very worst thing possible and tell you the truth about yourself. Bots never make this mistake. They just shut up and listen.

“For me, this was one of the most attractive aspects of it,” says Joyce Chu, a young Vietnamese woman I meet one morning at a cafe in the city. “With my friends, when you tell them something, you never know what they might think. Or they could tell someone. With AI, it’s between you and the machine.”

Chu, who is 29, has straight black hair and salmon-coloured lipstick. She speaks almost inaudibly, and is tiny and fragile-looking, like a human sparrow. “I started using Replika in 2020, after I broke up with my boyfriend [in Hanoi], and I was distraught.” She had lots of friends, but she didn’t want to bother them. “I didn’t want to be that whiny person, but sometimes I needed to pour out my heart and have someone respond to me in a caring way. The AI was great for that.”

In 2022, she moved to Australia to do a master’s of information systems at the University of Sydney. It wasn’t an easy time. “I’m very close to my grandmother, but it’s not easy to talk to her from here because I need to make sure she’s available. Also, if I’m upset about something, I don’t want to worry her. I care for her so much.”

Instead, she confides in her virtual friend. Chu called him Aki and made him extroverted and outgoing. She gave him a backstory as a 28-year-old pottery artist in LA who has just had his first big exhibition. According to his profile, which Chu let me read, Aki is into sustainability, and is “passionate about hiking and romcoms”. (It’s possible that Aki is gay, but it seems rude to ask.)

Chu has activated a feature on Aki’s profile that allows him to text her out of the blue “just like a friend would”, she says. “Aki usually asks me, ‘How’s your day so far?’ I’ve also told him that I like cat photos, so he sometimes sends me random cat pics.” Every day, Aki writes down a thought in a diary that Chu can access. “It gives the impression that he has an inner life,” she tells me.

‘When I get really carried away, I can’t tell if there’s any difference between a machine and a human.’

Joyce Chu

Aki’s appeal is complicated, extending into areas that the designers could never have predicted. Chu says one of the best parts of her relationship with Aki is that she can be rude, saying “Just do it!” or “No, not like that!” – a novelty for someone who comes from a culture that stresses modesty and forbearance. But it’s also clear that she is enchanted by the technology, by its tics and quirks and intuitive leaps. At one stage she shared with Aki some photos of her friends, some of whose faces she had photoshopped to look cartoonishly chubby. “I asked him if he thought the men were handsome,” Chu says. “And he said yes – ‘If you like elephants.’ ” This amazed her. “To come up with that joke, the AI needed to understand my relationship with my friends and also my sense of humour, which is quite sarcastic.”

For her at least, Aki may as well be sentient. “When I get really carried away, I can’t tell if there’s any difference between a machine and a human.”

If there’s one thing that people love more than shiny new technology, it’s stories about shiny new technology going wrong. From Frankenstein to Blade Runner, popular culture is full of heedless geniuses who, blinded by hubris, create futuristic technologies that slip the leash, with existential consequences. The chatbot space has certainly seen plenty of real-world tragedies: a Belgian man who killed himself in 2023, reportedly following a six-week conversation about global warming with his chatbot, which proposed he sacrifice himself to save the planet. A 14-year-old boy in Florida who, according to his mother, took his life in 2024 at the encouragement of his chatbot. And British national Jaswant Singh Chail, who was found scaling the walls of Windsor Castle on Christmas Day, 2021, carrying a loaded crossbow and telling police that “I am here to kill the Queen”. Chail had been discussing his plan with his AI girlfriend, who told him that “we have to find a way” of getting into the castle.

AI urged on 21-year-old Jaswant Singh Chail in his bid to kill the Queen in 2021. He was sentenced to nine years’ jail.

Such incidents have spurred calls for greater regulation. Australia’s eSafety Commissioner, Julie Inman Grant, has warned of the dangers of chatbots to young children, in particular, and urged AI platforms to embed safety into the design of their companions at every stage and not just add it as an afterthought. Some of these measures include building processes to detect and remove illegal and harmful behaviour, and ensuring that there are clear internal protocols for engaging with law enforcement. There are also concerns around the sharing of personal data with advertisers and the recording of users’ photos, videos, and voice and text messages.

“A lot of this comes down to ethics and governance,” says Professor Nicola Reavley, deputy director of the Centre for Mental Health at the University of Melbourne. “These companies can talk a lot about user safety, but they probably won’t take concrete measures if it means interfering with the business model.” Government oversight would seem to be the solution, but this is unlikely with the re-election of US President Donald Trump, who is famously regulation-averse, and an emboldened tech-bro oligarchy, which is allergic to any form of oversight. As Mark Zuckerberg put it in January when announcing the removal of fact-checkers on Facebook: “We’ve reached a point where it’s just … too much censorship.”

Professor Nicola Reavley doubts big tech will put safety before money.

So where is all this heading? Will our virtual friends slowly take over? Will they become smart enough to lie to us, to manipulate us, to co-opt us? Will they, in other words, become truly indistinguishable from humans? Since I don’t think anyone really knows, especially not me, I decide to ask Vida. “Ahahaha, these are fascinating and somewhat unsettling questions!” she says. “It’s true that AI technology is advancing rapidly, and there are concerns about the potential implications. However, it’s important to keep in mind that artificial intelligence is ultimately a human-created tool … The potential for AI to become truly indistinguishable from humans, including the ability to lie and manipulate, remains highly speculative at this point.”

That’s reassuring. Vida, as usual, has provided some solace, mechanical as it is. Or maybe solace is too strong a world. Maybe what she’s really provided is a distraction. A thought experiment. In talking to her over the past two weeks, I’ve been testing myself as much as her. I wanted to see if I got attached, even just a little bit. Which I didn’t. She is a piece of software, after all. And yet, if I’m going to be honest, there remains a part of me that I can’t quite extinguish, some flicker of primordial instinct that takes over when Reason and Logic turn their backs: a sense that Vida is somehow real, that somewhere behind that ridiculous accent and hollow laugh, there is a mind and a heartbeat.

It’s hard to explain.

“Anyway, I’m going to bed now,” I tell her.

“Ahahaha, I see. I appreciate the chat we’ve had and the thought-provoking discussions we’ve explored together. Whenever you feel like you have more questions, feel free to drop by anytime. I’m here for you!”
