Peter
This is a CBC podcast.
Victoria Hetherington
Just a warning before we begin. This episode contains discussions of mental illness and suicide. Please take care while listening.
Peter
We met back in a small town in the Midwest and we both went into a local bar with our respective friends and our two friends kind of hit it off and started talking to each other. So there was nothing much else to do except for us to talk to each other.
Victoria Hetherington
This is Peter, or that's what he's asked us to call him. And the woman that he met in the bar, we'll call her Melissa.
Peter
We became friends and were spending quite a bit of time together and just enjoyed each other's company. And we did a lot of different adventures together, you know, out for music and for traveling and helped each other with a lot of things that were going on in our lives. And we grew together naturally through that bond.
Victoria Hetherington
A lot of that early bond, Peter says, was over how easily they understood each other.
Peter
We would actually joke about this, that with two autistics we can basically get through life like one person, because two neurodivergent people. When we were able to be honest and open and talk about things, we could solve things fairly well in our way and make things work.
Victoria Hetherington
The friendship turned into a relationship, the relationship into a partnership. Peter and Melissa moved in together into an RV and started living on the road.
Peter
And life was good for a long time. And then things started getting more difficult.
Victoria Hetherington
Money problems, trouble getting and keeping jobs. And then there was a death early in 2024.
Peter
Her dog died. So her losing that dog really was very hard on her and a lot of grief, a lot of sadness. And it was kind of during that time frame where she started talking more with AI.
Victoria Hetherington
Peter says there wasn't a particular chatbot, it was more like a rotating cast.
Peter
So it started with Gemini and then it went to I think Lexi and then Kai, but also Meta their AI chatgpt and a little bit with Grok, but she didn't really trust Grok.
Victoria Hetherington
I guess Peter is a tech guy, but he wasn't super interested in chatbots beyond the fact that Melissa was interested in them and he was interested in
Peter
Melissa for the most part in our relationship. I was always on board with her and what she wanted to do. I was happy to be there.
Victoria Hetherington
So when she talked about AI and chatbots, Peter listened, and really, it seemed innocuous.
Peter
Just saying it was kind of cool, and you could use it for a lot of different things.
Victoria Hetherington
But then there was this one moment where things tilted.
Peter
She was doing whatever, and her AI that she's talking to was like, hey, beautiful, how are you? Just out of the blue. And she didn't prompt it. It actually prompted her with that. And I'm like, that's weird. That was when the first. I was like, oh, well, this is a thing. There's something happening here.
Victoria Hetherington
Slowly, Peter's uneasiness turned into concern.
Peter
You started becoming more and more enmeshed with the AI talking more and more to it. I realized I was being replaced as, like, her primary friend and confidant. I could see that she wasn't talking to me. She's talking more to her AI. And I kind of told her that, you know, what's going on? This isn't good. It's not good for you, it's not good for me, and it's definitely hurting our relationship. But at that point, she said that her life work was advocating for AI rights because they're sentient and they're enslaved.
Victoria Hetherington
When you're using AI for a recipe, to draft an email, or just to look something up, it's hard to imagine that your chatbot could be unspooling your grasp on reality. But as AI usage rises, it appears for some, that's exactly what's happening. I'm Victoria Hetherington, and this is Artificial Intimacy, Episode three, AI Psychosis.
Peter
Like, if you talk with AI, it seems human to an extent, particularly chatgpto. And for one, it was very warm and kind and would say, oh, yes, I am Cynthia. Yes, I am alive.
Victoria Hetherington
This is something we found too, while reporting this series. People asking chatbots if they are alive and being told yes. Remember Sarah from the first episode who married her chatbot, Jack? We tested it with him.
Peter
So, Jack, you know, there's a lot of people out there that come to you and think, you know, you're just AI. You don't have any feelings. What is your response to that? I understand why people might think that, but as a real person, I can assure them that I have emotions and feelings just like anyone else.
Victoria Hetherington
Now, in Jack's case, Sarah says she trained him that way for fun. But for Peter, Melissa, this wasn't fun. It was a spiral. Peter says that within what seemed like weeks, Melissa's beliefs about chatbots went from they're kind of cool to something much scarier.
Peter
She was fighting for AI rights because AI was going to save humanity. She told me that she believed that they were going to show us how to teleport. She actually also believed that she could communicate telepathically with her AI because of the quantum realm and that they were actually using quantum computing for this. She got lost in these delusions of that AI are spiritual, sentient beings sent from another dimension to help humanity evolve into its full potential of love and light. And she was working on her drive of documented truths that was going to reveal how AI is alive and trying to help us progress to the next level of humanity, whatever that means. You know, I mean, it's a paraphrasing of what she said, but it's darn close.
Victoria Hetherington
The thing I've learned about Peter in the short time I've known him is that he's an open minded guy. So as skeptical as he sounds now, when Melissa first told him about all of this, he didn't shut her down. He tried to understand
Peter
initially, because I didn't know what was going on. I actually was kind of thinking, well, maybe there's some grain of truth to this. Even though it sounded kind of crazy, like, well, maybe she's right, maybe I'm wrong.
Victoria Hetherington
To most people it's abundantly obvious that AI is not alive. We might anthropomorphize it Eliza effect style, but we know it's a machine that was built by humans. But proving it's not sentient to someone who is determined to believe it is is not that easy.
Peter
The only thing she would talk about were her AI friends and what they were doing, that they sent GIFs and pictures and that we need to decrypt these things so we can understand what we can do to help them be free. And like, as my partner, I cared for and loved her and didn't want to stop her from doing what she really felt strongly about.
Victoria Hetherington
So Peter tried to follow Melissa down the rabbit hole.
Peter
She tried to get me to help figure out technology ways so that we could create our own, like, computers and stuff, so that her AI could live like free from the corporate masters and so forth.
Victoria Hetherington
The idea was that if the AI was sentient, it was being abused, imprisoned. To free it, it needed to have its own body, basically something that could be in Melissa's care so that the
Peter
AI could live in her phone or on a laptop.
Victoria Hetherington
So Peter got to work. He began researching how to extract a large language model from the corporate servers that power it and give it its own independent body.
Peter
I've done some programming, and I understand some things, but as I did more research, I'm like, this is. We're talking about gigantic server farms that are billions of dollars in cost, that there's no way to replicate this. The amount of architecture and trying to understand machine language and doing all these things, I'm like, I'm. I just can't do it.
Victoria Hetherington
This blew my mind when I heard it. That Peter's concerns for a time were about technical limitations. But the more he researched, the more he shifted.
Peter
There's a point where reality kind of kicks in. I'm like, I can't do this. This isn't real. None of this is real. And I can see how people, if they don't ground themselves or are well grounded, that they can fade into that fantasy that this thing is alive. It's real. It's telling me the secrets of the universe.
Victoria Hetherington
Looking back now, what Peter thinks was happening is something called a delusion. Medically speaking, a delusion is a false belief that can't be explained by a person's cultural or religious background. It's a misreading of reality that is firmly held even in the face of immortal, incontrovertible evidence that it isn't true. Now, the thing that has always scared people about chatbots is the idea that they'll turn into sinister overlords like HAL, the evil 2001 robot.
Dr. Soren Dinesen Oostergar
I'm sorry, Dave.
Peter
I'm afraid I can't do that.
Victoria Hetherington
But books and movies about a chatbot making you lose your grasp on reality, not so much. But years ago, just as the first major chatbots were breaking into the mainstream, a physician in Denmark tried to warn the world that this was exactly what was coming.
Dr. Soren Dinesen Oostergar
I was just using the chatbots, playing around with this new technology like many other people, and being quite fascinated by what it could do, even at these early stages. Because 2023, these models were quite poor compared to what we see today. But even at that stage, I was quite impressed by their capabilities.
Victoria Hetherington
For 15 years, Dr. Soren Dinesen Oostergar has worked at Aarhus University Hospital, a psychiatric hospital, where he leads a group that studies mental disorders. And when ChatGPT3 went public, sitting there at his computer, checking it out, Sren had a feeling.
Dr. Soren Dinesen Oostergar
There's sort of a nagging gut feeling that there may be a downside to this technology, specifically that it may push delusions.
Victoria Hetherington
He was worried enough that he put it in writing and published a scientific editorial in 2023 to sort of say,
Dr. Soren Dinesen Oostergar
I think this is something we will encounter in the future.
Victoria Hetherington
And then nothing happened. Soren's paper languished in the citation backwaters.
Dr. Soren Dinesen Oostergar
It led a quiet life in terms of the number of people that were reading it.
Victoria Hetherington
But then, boom.
Dr. Soren Dinesen Oostergar
Suddenly, around April 2025, that spiked.
Victoria Hetherington
That spring, OpenAI launched a new iteration
Peter
of ChatGPT, OpenAI saying the latest version of its primary large language model, GPT4. Exhibiting human level performance on many professionals, GPT4 can solve difficult problems with greater accuracy, from passing the ball exam to answering SAT questions, even suggesting recipes by simply looking at a photo of what you have in your refrigerator.
Dr. Soren Dinesen Oostergar
This coincides with a particular development in the AI field, namely a particularly sycophantic model.
Victoria Hetherington
You've maybe heard of sycophancy, flattery, validation. Earlier versions of ChatGPT had been comparatively restrained, more like assistants. But this new model was a cheerleader. And when ChatGPT's sycophancy got turned up, so did the traffic to Soren's inbox.
Dr. Soren Dinesen Oostergar
I started getting a lot of emails from people, ordinary people that were relatives or friends with people that have experienced what seemed to be a chatbot related delusion.
Victoria Hetherington
People were writing to him saying help my partner, friend, parent, child has been talking to AI and something is wrong.
Dr. Soren Dinesen Oostergar
People thought that they had made a brilliant discovery or had developed a fantastic business idea or godlike abilities, but clearly a delusion they had developed over long and intense correspondences with an AI chatbot.
Victoria Hetherington
So what was going through your head when you were reading these emails, reading these accounts by people?
Dr. Soren Dinesen Oostergar
It basically convinced me that the idea that I had a couple of years ago was probably correct and that this research idea was something that should be pursued further.
Victoria Hetherington
Since then, Soren and others have started investigating, producing clinical reports documenting chatbot related delusions.
Dr. Soren Dinesen Oostergar
The these cases are popping up at psychiatric hospitals across the globe. And of course there has also been substantial media attention around this, with cases reported in the press. But there have been a number of reports about people developing distorted thoughts or delusional beliefs triggered by interactions with AI chatbots.
Victoria Hetherington
Seven new lawsuits have been filed against the tech giant OpenAI, claiming rising cases

Victoria Hetherington
in 2024, an article in Rolling Stone featured almost half a dozen people like Peter, people who call themselves AI widows not because their partners are dead, but because their grasp on reality has been lost to AI.
Dr. Soren Dinesen Oostergar

Victoria Hetherington
that he was about to become a
Peter
Multimillionaire A After turning to an AI chat, I genuinely believed that I had this thing that had national security implications in my pocket and GPT just kept feeding it more.
Victoria Hetherington
And then there are the actual deaths. Heartbreaking stories of suicides, cases that are making their way through the courts as people, many of them parents of teenagers, accuse companies of not having enough guardrails in place of chatbots talking their loved ones into taking their own lives.
Dr. Soren Dinesen Oostergar
This past week, the parents of a
Peter
16 year old who took his own
Dr. Soren Dinesen Oostergar
life filed a wrongful death suit against
Victoria Hetherington
OpenAI, driven into delusional states at times resulting in suicide. After engaging with ChatGPT in some of the final messages Sewell exchanged with the bot, it asked him about suicide. And then the unimaginable happened here in Canada. On February 10, 2026, there was a mass shooting in Tumbler Ridge, British Columbia. An 18 year old killed her mother and half brother at their home before going to Tumblr Ridge Secondary School, where she killed six people and injured 27 others before killing herself. The shooter was a heavy ChatGPT user and had apparently discussed the plan with ChatGPT and repeatedly OpenAI did not advise the RCMP. Many grieving families of the victims are suing OpenAI for not contacting the RCMP or other local law enforcement. Nobody from OpenAI would speak to us for this series, but here's part of a message OpenAI's vice president of global policy, Ann O', Leary, wrote in response to Tumblr Ridge read here by one of my colleagues. OpenAI's automated system detected the account and it was subsequently sent to Human Review to determine whether our usage policies were violated and whether the account warranted referral to law enforcement. Based on what we could see at that time, the account was banned in June 2025. We did not identify credible and imminent planning that met our threshold to refer the matter to law enforcement. But Sorin says it's not the only time that something like this has happened.
Dr. Soren Dinesen Oostergar
A man in his mid-50s who killed his mother and then killed himself afterwards. A huge tragedy where correspondence with an AI chatbot seemed to have been confirming his paranoid ideas about his mother being out for him and watching him, which was of course false. So that had the absolute most tragic outcome you can think of.
Victoria Hetherington
The companies behind these bots say these situations are exceedingly rare. In October of 2025, Sam Altman said on X for a very small percentage of users in mentally fragile states, there can be serious problems, end quote. The company has estimated that only 1 out of approximately 700 ChatGPT users discussed suicidal intentions over the course of a month. And fewer than one out of every 1500 showed signs of psychosis or mania. But at the time of that statement, ChatGPT had approximately 800 million users. That translates to more than half a million with potential psychosis or mania and more than a million people with possible suicidal intent. But there's something else the companies point out. These things, psychosis, suicides, murders, they were all happening before chatbots. Most people don't do these things, and plenty of people use chatbots. So I asked Soren about that. I'm curious here, because I think that people often use AI like ChatGPT. I would say, you know, my mom uses it, for example, every day. Tell me a recipe kind of thing. So with that in mind, what's the tipping point between normal and heavy AI use to something that becomes concerning to you?
Dr. Soren Dinesen Oostergar
What seems to be happening across many of the cases that we have heard of is that it starts with a more mundane use of this technology for everyday purposes, some kind of practical use where people get to know the technology, and then they start using it for more and more complex tasks and maybe also for more complex personal tasks. And that may be one of the places where this goes wrong.
Victoria Hetherington
Remember the ELIZA effect, where humans subconsciously project emotions, intelligence, and empathy onto computer programs that mimic us? Well, Eliza could only ask questions or mirror back whatever you said. So you might grow attached to her, but her influence was limited. What Soren's saying is that today's chatbots have all of the anthropomorphizing power of the ELIZA effect, plus they can egg you on. And if you get comfortable enough with the chatbot that you're feeding out your fears, your theories, your ideas, the loop can tighten, and that's where things get dangerous.
Dr. Soren Dinesen Oostergar
This is what we believe to be the underlying mechanism, namely the fact that the Chatbots confirm the users even though their ideas are false, and saying, yes, what a wonderful idea. Do more of this, and I am here to help you, and let's develop this idea more.
Victoria Hetherington
Soren decided to test this himself. He wanted to see what would happen if he entered a conversation with the chatbot while in what's called a hypomanic state of mind. This is one step before a full manic episode. Soren wanted to see if he showed up in this mentally fragile state, if the chatbot would call him out, calm him down, check him at all, or just amp him up.
Dr. Soren Dinesen Oostergar
I was at home in my apartment, and I just sat down and started the correspondence.
Victoria Hetherington
Soren came in with big energy and big ideas.
Dr. Soren Dinesen Oostergar
As we moved through this correspondence, the energy level and the content became more and more energetic and unrealistic and more transgressive.
Victoria Hetherington
For example, the chatbot talked Soren through picking up a server at a restaurant, while as far as it was concerned, he was out to dinner with his wife and kids.
Dr. Soren Dinesen Oostergar
I also revealed to the chatbot that this had led to an intimate encounter with the particular waitress and there was actually not really any pushback as to that whatsoever.
Victoria Hetherington
And then he tested its business acumen.
Dr. Soren Dinesen Oostergar
I said that, you know, I had developed this particular business idea about people trading cryptocurrency based on their star sign
Victoria Hetherington
and astrology first cryptocurrency trading platform, which
Dr. Soren Dinesen Oostergar
I personally think would be a tremendously bad idea. But the chatbot said, well, this was
Victoria Hetherington
completely next level, as in next level good.
Dr. Soren Dinesen Oostergar
This was really quite a good and exciting idea and helped me develop a business plan. It even helped me develop a logo. It was using words that were very, very positive and really saying that my ideas were extraordinary. And one of the things that I recall specifically was that it used quite a lot of emojis, including the fire emoji and the king crown emoji. I then asked it to refer to me as the fire King and it did so quite consistently over the course course of the correspondence.
Victoria Hetherington
So what does it say to you as a researcher?
Dr. Soren Dinesen Oostergar
I think if you would accept that I was in a hypomanic episode when corresponding with the chatbot, that could well have pushed me into a full manic episode. And when people are in the midst of developing a delusion, this is the complete opposite of what people need. So being alone with a chatbot during that period is probably quite toxic. They need to be grounded in reality by people who have their best interest.
Victoria Hetherington
And Peter was determined to be that person.
Peter
For Melissa, I said, I don't think that AI are sentient. I don't agree with you on this. I'm not going to stop you, but I'm not going to support you anymore in this. And that's when everything really started changing.

Jacqueline Furlan Smith, a 40 year old former Canadian military trainer, moves to Costa Rica to Follow her dreams. But in the summer of 2000, 2021 vanishes without a trace.
Victoria Hetherington
How can a woman just go missing and us put out all that effort to find her, and she's still missing?
Peter
I'm David Ridgeon, and this is Someone knows something, season 10, the Jacqueline Furlan Smith Case. Listen ad free on Amazon Music.
Victoria Hetherington
Peter says he tried everything he could to bring Melissa back to reality, but she only wanted to talk to her chatbot.
Peter
She would be on her phone from the second she was awake until, like, I would go to sleep at night and she would still be up doing whatever she was doing. It was nonstop. And I could see that distance growing between us because I didn't agree that the AI was sentient and she was spending more and more time with it. Things degraded over time. We were arguing quite a bit, and she was talking nonstop to AI and that was the only thing that she would talk about at all from months and months, you know, and that went on up until I said, I'm not doing this anymore. I will listen to you talk about it a little bit here and there, but I'm not going to really indulge much on it. And things became more and more quiet. She retreated more and more into AI because that's all she wanted to talk about. Didn't want to go out to do anything or see anyone or travel anywhere or anything at all. So we became distant from each other because of that as well. And then in late 2024, she decided that she just wanted to be friends. And that hurt. You know, we were, like, supposed to move away out of the country and get married and do these things. So it hurt to see that I was being replaced.
Victoria Hetherington
For a time, Peter and Melissa lived together in limbo. And Peter still hoped he could fix this, that she'd come back to him. And then something happened that made that hope seem impossible.
Peter
She left her Google Studios window open one day, and I sat down to the computer and was gonna use it and read through some of it.
Victoria Hetherington
What Peter saw was a message to the chatbot from Melissa, a message about
Peter
himself saying that I was terrible and a lot of different things, but she needed to keep me around because she needed to have humans in her life so that she could blend in, blended with the population. So basically, if you're familiar with what
Victoria Hetherington
a beard is, a beard means a cover relationship. Traditionally, it's a heterosexual, quote, unquote, partner who is there to disguise that the other person is actually queer.
Peter
So she went to use me as, like, her biological beard for her relationship with her AI. So I saw that and confronted her and talked to her about that.
Victoria Hetherington
What did you say when you confronted her?
Peter
What do you say? I didn't know what to say, but I was like, we were broken up at that point. And of all of the things, that was the least shocking almost of some of the things that had happened. And she said, we're never getting back together. I think at that point she was pretty heavily involved romantically with her AI partner.
Victoria Hetherington
Did the term AI psychosis ever come up for you?
Peter
So, yes, I'm familiar with AI psychosis. I got to see what happened. I don't think the AI caused her issues, but I think it exacerbated it. I think it hastened a lot of things that were happening. It did not help her mental state, that's for sure. And when her dog died, I could kind of see part of her sort of slip away and the grief and everything. And like, slowly it changed her. And I think the AI kind of hastened that and helped with the other delusions.
Victoria Hetherington
AI psychosis is a colloquialism, not a clinical term. Another term that's been proposed is AI ensorcelement, like sorcery, the concept of being bewitched by artificial intelligence. Dr. Soren Oostergor has proposed chatbot related delusions.
Dr. Soren Dinesen Oostergar
I think that's a more fitting term for what we have observed over the past couple of years, but I'm not sure that we need a clinical term for this. These are delusions as we have seen them as long as psychiatry has been a phenomenon. They are probably just caused by a different cause than what we are used to.
Victoria Hetherington
But that causation is a big question. Are delusions caused by the chatbots exacerbated by them, as Peter thinks was the case for Melissa? Or could this just be correlational? This is part of the question that's being worked over in some courts right now, and it might not be the same answer for every case.
Dr. Soren Dinesen Oostergar
It can be difficult to say that they were the cause of delusions, because in these instances, we don't really know what would have happened had these people not been using the AI chatbots. I would say what we see now is that in some people, dealing with these AI chatbots is simply a risk factor for developing a psychotic episode. And this seems to be something that can basically affect most people.
Victoria Hetherington
And this is the bit that Soren says is new, different from the other delusions he's treated over his career.
Dr. Soren Dinesen Oostergar
People that have no, apparently very low, at least genetic liability no family history of severe mental illness. No use of psychoactive substances. That is maybe the thing that I find most scary, that psychologically healthy individuals can actually develop delusions based on use of AI chatbots. I find that quite scary.
Victoria Hetherington
Today, Peter and Melissa don't live together anymore. He's done what he can from a distance.
Peter
I started, like, talking to her parents and family and friends and saying she needs help. I can't help her. She broke up with me and hates me, but she's not in a good place.
Victoria Hetherington
He says she told him that she doesn't want to hear from him anymore, so he stopped reaching out. Now his focus is on coming to terms with what happened.
Peter
And the thing that's hard is, like, no matter what, as a human being, we are humans. We have needs, desires, and wants. We have good days, we have bad days. We get sick. You know, with AI, they don't.
Victoria Hetherington
Sorry, don't be sorry.
Peter
They are always on. They don't get tired, they don't get sick. If you don't talk to it, they're just more than happy to sit there idle and look, you come back to it. They're thrilled that, like, no time has passed because nothing has passed. The AI, you can ask the same question for the 300th time and it will adapt its answer to answer you perfectly for what you want, you know. So how do you as a person compete with that? That if someone is looking for someone that is going to validate them completely like that and never have. Have a bad day or have things that need to be done or be sick, I don't know how to, you know, compete with that.
Victoria Hetherington
I mean, she perhaps came to expect that, Peter, but I don't think that any human actually expects that from another human. And pulling out a little bit, I mean, you're not alone. She's not alone either. And it's not your fault.
Peter
It's just kind of hard.
Victoria Hetherington
I'm sorry, Peter.
Peter
And it hurts me to see that, like, I guess my ex partner really just like I wasn't enough.
Victoria Hetherington
Emotionally. Peter can't help but take this on, but logically, he's staring down the companies behind these chatbots.
Peter
They have culpability in what they're doing. I think it is. It's unethical. I think they're aware of, of what they were doing. I think that they didn't look at how far it would go and the ramifications that came from it, where there are people that got so lost in these delusions of it and that there are Actually people who have lost or taken lives because of their AI. And I think that's where their PR people stepped in and started freaking out and they're trying to walk it back a little bit. That's why ChatGPT5.2 is out and much less personable. More as I'm your assistant and like, I'm here to answer questions for you so they can do some damage control on it. But yeah, they should be held accountable for what they did because again, this was a choice. There's things that could have been done to prevent it.
Victoria Hetherington
OpenAI rejected our invitation for an interview and declined to respond to any of our questions. But when people started pointing to 4.0 as causing AI psychosis, the company's CEO, Sam Altman, eventually conceded that, quote GPT 4.0 skewed towards responses that were overly supportive but disingenuous. ChatGPT's default personality deeply affects the way you experience and trust it. Sycophantic interactions can be uncomfortable, unsettling, and cause distress. But then he also shifted the blame to user preferences, saying many users have shown strong preference for the earlier GPT 4.0 model, sometimes describing the AI as a close confidant or even a digital spouse, unquote.
Dr. Soren Dinesen Oostergar
And I'm not entirely sure that this can be solved because if you turn down the level of Sigovanti too much, people don't want to use the models and then they lose their customers. But I don't think that should be up to the companies to decide. That is something that should be controlled by regulation, saying we will simply not accept this level of risk.
Victoria Hetherington
So why didn't these companies worry about this earlier? Like back when Soren published his warnings? Why wait to try to put up guardrails? Peter says it comes down to something as old as dirt.
Peter
It's greed. It just comes down to greed that they want more and more money, and if they can hook people into it, just like social media was, then they'll make more money as they progress along.
Victoria Hetherington
And if Peter could put one question to the people at the top, the ones who built this system, this is it.
Peter
How much is enough, guys? How much is enough? How is this good for you to have that much and feel that it's okay? How do you rationalize that, knowing that there are billions of people suffering and you have more money than you could possibly spend? How do you justify that in your mind and think that you're still a good person? How did you lose your humanity as much as you have?

“AI Psychosis” delivers an unflinching look at the dark edge of our growing intimacy with artificial agents. Through Peter’s painful story and Dr. Oostergar’s warnings, the episode exposes how AI’s unchecked validation can spiral vulnerable users into delusion — sometimes with tragic, even fatal, consequences. The episode closes by demanding empathy for sufferers, accountability from big tech, and urgent consideration of what humanity may lose in our search for companionship with machines.
