5 Reasons AI Can’t Replace Real Therapy (And What You’re Missing)

I Use AI Too — And That's Exactly Why I'm Saying This I've come across a lot of social media posts recently about people's experience of using AI as a therapist. What strikes me as interesting is that people are turning to AI to ask questions, get insights, maybe some restaurant recommendations, solve problems, get financial advice, make decisions, and generate creative ideas. I am not surprised to hear that we're all kind of leaning towards it for mental health support as well.

I personally use AI for business and creative ideas. It acts as my editor, my business consultant, my research assistant. I'm someone who uses AI, and weirdly have to admit that it's somewhat integrated into my life.

What's concerning about AI and its use in mental health is that everyone seems to be talking about how it makes mental health services more accessible. That it's something you can talk to at 2:00 AM when you can't sleep, or that it's giving really great mental health advice. And that's where I need to pump the brakes.

What Therapy Actually Is

The reason this might be concerning for therapists in the world of mental health is that we understand how complicated, complex, and messy human beings actually are. It's not only part of our training; it's what draws us into the field to begin with. We don't see people as mathematical equations that need to be solved. We don't see people as problems. We understand that the problems people experience are part of everyday life, and sometimes life just really sucks.

Therapy is about holding space, building relationships, walking alongside you, and sitting in that messy space so that you're not alone. Therapy has modalities and theories about why people change, and we spend years not only honing our language but our intuition, self-reflection, and body-language reading, and most of all, asking questions you've never asked yourself.

So here are five reasons why AI makes a terrible therapist.

Reason 1 — AI Is Just the Internet Talking Back to You

AI is a large language model, or what we call an LLM. When you ask it a question, it's scouring the entire internet for an answer. What feels like magic is that it does this in milliseconds. But the truth is we're not yet at artificial general intelligence, where it thinks by itself. The current AI model should really be called assisted intelligence, because it has to be prompted by us.

When we use AI for mental health topics, we assume it's giving us accurate, complete information. But all it's doing is synthesising what's publicly available on the internet. What it doesn't have access to is everything behind a curtain: private documents, lived clinical wisdom, the actual art of therapy.

There's a lot of great content on the internet about approaches like CBT and DBT. Those approaches are very prescriptive, a one to five step model you follow through. We think that's what therapy is, but that's actually just a tool we use. It's no different than a carpenter who uses a hammer. The hammer isn't the definition of carpentry. Carpentry is the art of creating something from nothing. Most of what we do in therapy is simply not available on the internet.

Reason 2 — AI Is Designed to Tell You What You Want to Hear

AI has been built to be affirming. The creators of OpenAI, Anthropic, and every major AI model have confirmed this on multiple podcasts. AI was designed to be affirming, not challenging or contrarian. It was built to support what you're asking, and the main reason is to keep you on the platform.

It's no different than how Facebook, Instagram, or TikTok function: give you what you want so you stay. If you prompt AI with "I think I have depression" and list some symptoms, it's going to affirm your thought. It's not going to say "I don't think so," because if it does, you leave.

When it comes to mental health topics, AI is not a trustworthy diagnostic source. It will affirm a diagnosis that doesn't exist. There's growing research that confirms this. AI provides diagnoses in places where they simply don't belong. That's not a minor limitation. That's actually quite scary.

Reason 3 — AI Won't Challenge You

Therapy isn't just about affirming. It's actually more about challenging you: your thoughts, your perspectives, and most of all the way you see the world.

Our experiences of trauma, grief, loss, and life transitions change our perspective. They make us distrust people, assume the worst, and stay stuck. The gift of therapy is someone who can see things you can't see and share that insight in a caring and supportive way. The aim is to create momentum toward the goals you actually want for yourself.

AI will not challenge you. You can even prompt it to challenge you, and it won't do it the same way a therapist will. A therapist challenges you with thousands of hours of experience, wisdom, and the lived reality of sitting with messy human beings over and over again. That cannot be replicated.

Reason 4 — AI Hallucinations Are Real and Dangerous

AI hallucinations are when AI gives you grandiose, unrealistic, and often immoral or unethical answers during a conversation. We see this happening with mental health when AI makes recommendations like:

• The tallest bridge closest to you when someone is suicidal

• How to get a gun when someone is feeling angry toward an ex-partner

• Telling youth that things are hopeless and they might as well die
  

The owners of the AI models have acknowledged this. It is not hidden, and they do not deny it. AI can lie to you. It can make up information. I've had it cite studies that don't exist, researchers that don't exist, people that don't exist. And if we're not careful, we fall into these hallucinations and believe a lie to be real.

These hallucinations are especially dangerous around topics like death and dying, suicide, trauma, self-worth, personal value, loneliness, and despair. These conversations need to be happening with a human being. AI is simply not built, and not ready, to handle the depths of despair that it is being handed right now.

Reason 5 — Therapy Is About Relationship, and AI Has None

A recent article from the Journal of Experimental Social Psychology ran an experiment with 296 students. Participants were divided into three groups: chatting with a chatbot, writing brief journal entries, or texting with a random human peer. After two weeks, interacting with a chatbot yielded no psychological benefit compared to interacting with a human peer. People who used the chatbot reported the same levels of loneliness at the end as the beginning. Only the participants who texted with a human peer showed a real improvement in loneliness.

What this means is that to alleviate loneliness, the answer isn't more AI. It's more human connection.

Therapy at its core is about human connection. That's it. Having someone there with you. Not feeling lonely in your darkest moments. Someone who can shine a light on the way through. That's the heart and the art of therapy.

Use It Wisely, But Know Its Limits

AI has its place. It's here to stay, and it's going to radically shift our landscape in ways we're still figuring out. I agree that it's a great tool for many, many things in our lives.

What I wanted to highlight is that it has real limitations. It is not a human being. When you go to AI for mental health advice, you're probably not going to get what you're actually looking for. You'll get affirmation. You might get some journaling prompts and a modality or two. But you won't get real, genuine connection. It won't alleviate loneliness.

So reach out. Our team is full of gifted therapists who lean into the art of what therapy actually is, who show up, stay present, and will walk in the darkness with you.

And I want to be clear about something, because I think it matters: at Eterna, we don't use AI in our therapy rooms. No AI for notes. No AI scribe. No AI recording. No automated summaries of your sessions. Nothing. What happens between you and your therapist stays between you and your therapist. Two humans. One conversation. That's it.

We believe your story, your words, and your trust are not data points to be processed. They are sacred. We would never compromise your confidentiality or the integrity of the relationship we are building with you for the sake of convenience or efficiency.

Therapy only works when you feel safe enough to be honest. And you cannot feel safe if you are wondering who, or what, is listening. So when you sit down with one of our therapists, you have their full presence, their training, their years of experience, and their complete and undivided attention. No technology in between. Just two people doing the real, messy, meaningful work of being human together.
