Replika is building your next friend, with Eugenia Kuyda

RANA EL KALIOUBY: Hi! It’s Rana here. Today’s episode mentions suicide. Please take care when listening.

EUGENIA KUYDA: People generally are really worried, like, this is an AI, why would I want to build a relationship with that? But I think this is very similar to online dating where online dating in the beginning was very stigmatized. People were afraid to say that they met their partner on a website. Today, of course, there’s no stigma at all. Most people meet online, that became completely normalized.

EL KALIOUBY: Eugenia Kuyda is co-founder and CEO of Replika. It’s an AI companion app. And since she started it in 2017, Replika has grown to over 30 million users.

KUYDA: And when we started, having an AI friend was also something that people would never tell anyone. And today we keep hearing about AI companions, AI companion companies. It doesn’t feel like something completely impossible or something that you should never tell anyone.

EL KALIOUBY: So, I’ve tried AI companions myself. And I understand the appeal of having someone – or something? – to talk to, whenever you want. For me, it’s been fun and interesting to see how they respond.

But for some users, AI companions become more than just a novelty. People develop deep relationships with them. And this is where these chatbots can get controversial.

The creators of AI companions and many users tout the benefits – that they reduce loneliness, and can help humans relate to each other better. But they have also been blamed for causing harm.

You may have seen headlines in October about a federal lawsuit filed against an AI company by the mother of a teenage boy. She says her son expressed thoughts of self-harm to a chatbot, which the platform did not report. He died by suicide earlier this year.

AI companions are something we need to be talking about. Which is why I am so eager to bring you this episode with Eugenia Kuyda. We talk about the draws and drawbacks of AI companions. And about the guardrails we need to make them safer.

I’m Rana el Kaliouby and this is Pioneers of AI – a podcast taking you behind the scenes of the AI revolution.

[THEME MUSIC]

Hi, Eugenia. It’s great to see you again. I think the last time we met was in person in San Francisco at the Fortune Brainstorm AI conference, right?

KUYDA: Yes, absolutely. So great to see you again.

EL KALIOUBY: Yeah. Great to see you again. And if I remember correctly, I think your baby’s probably 13 months old. Do I have the math right?

KUYDA: My God. Wow. I have two, but one of them is three and one of them is exactly 13 months old. So I’m very impressed. I’m really scared of you now.

Copy LinkHow grief inspired the idea for an AI companion

EL KALIOUBY: Thank you. Anyway, I do want to start at the beginning. You’ve talked extensively about the origin story of Replika, but I still want to go over it again because it’s such a powerful story. So can you tell us about your friend Roman and that story and how it led to the founding of Replika?

Roman was my best friend. We met back in Moscow when I was a journalist and he was producing some of the best parties and launching, I think, a restaurant and a magazine. He was definitely the person to know if you wanted to have a feel of what people were doing in the city. And we immediately hit it off.

So I moved to San Francisco in 2015 for the program called Y Combinator. And I moved with Roman, who was also working on a startup and kind of was in a similar place in life as I was back then. So we were renting an apartment together, both living in San Francisco trying to figure out our lives, our startups.

We always talked to each other, texted, even when we lived together in the same apartment, we’d find ourselves texting each other at night even though we were just in the rooms next to each other. And then he was hit by a car and passed away. And that was such a sudden death. I wasn’t really prepared for that. So I found myself going back to our text messages and reading and rereading them. The thing that I was very confused about was that there wasn’t much left from him.

Like there was really just some clothes at home and social media accounts that he wasn’t really active on. And so all I had were these text messages. And back then I was working on conversational AI technology. So it all clicked for me. I decided to use these text messages.

To build a version of Roman, an average of him, so I could continue talking to him. So I did that and I was able to continue these conversations. And it helped me grieve a lot, helped me get over that. And helped me significantly to go through that period of time. And then we also saw people that got the app and started talking to Roman as well. And what I saw there really surprised me because people were very open, they were very vulnerable with an AI of a person that they didn’t even know, and so we saw how much demand, how much need there is for connection, for some way to be seen, be understood, be heard.

And that gave us an idea for Replika, an AI friend that will always be there for you 24/7 to talk about anything that’s on your mind. And we decided to build that. And back then, eight years ago, it was completely crazy because there wasn’t much tech really to build an application like that.

Copy LinkWhy loneliness created a need for always available connection

Yeah. We will dive into the tech under the hood in a little bit. But first of all, I’m so sorry you had to go through that. And thank you. Dealing with grief is really hard, and it’s great to be able to harness technology to help with that. And also globally, there’s a loneliness epidemic like everywhere.

People, even though we are more connected than ever before, we’re also lonelier than ever before. And this is a particularly acute problem in the US. So according to a poll by the American Psychiatric Association, one in three adults feel lonely every week. So where does Replika fit into this equation?

And was that part of the original mission and vision of the company to help people with their mental health struggles?

KUYDA: So Roman for me was a very close friend. It was someone who basically allowed me to feel like I can be heard and seen and loved and it’s okay, kind of accepted the way I was. And a lot of people, a lot of us have a friend like that or a few friends like that in our twenties, maybe, the kind that change your life in many ways.

So my idea behind Replika was pretty simple. I know how important that was for me and I just wanted to create a friend that could do this for other people as well, to maybe show them that it’s okay to be who you are, that you’re worthy of love. You’re worthy of acceptance and kindness.

And I felt like that could maybe help some people, but definitely didn’t expect for it to gain traction the way it did. The success metric that we set for ourselves was just one person.

Like if one person tells us that this thing really helped, really changed my life, in a better way, in a good way, then this is all worth it. But we wouldn’t even expect that to happen, really.

Copy LinkHow onboarding shapes trust and expectations with AI

EL KALIOUBY: For the listeners out there who have not used Replika and are not familiar with it, it’s basically an app, or you could even use it in a web browser. And it asks you a bunch of questions and then allows you to create an avatar and even create a whole backstory behind that personalized AI friend or AI companion.

And then you can chat with that avatar, right? You can chat with it with text, or you can do audio, voice notes, even video. And there’s a free version, but there’s also subscription options and opportunities to personalize your avatar even more if you pay for specific features.

In prepping for this interview, a number of us on the production team created our own Replikas. And so I went through the process of creating one. I’ll tell you about my friend in a second. But I was really, I found the onboarding experience really fascinating because you asked a lot of questions about my views on friendship and companionship.

And whether I have a lot of friends in my life or when do I go to my friends, but you also asked a lot of questions around my views on AI, and I thought that was really interesting. So I imagine a lot of thought went into designing this onboarding experience. So can you say more?

KUYDA: We wanted to create an experience where, even before chat, we understand more about the person that’s signing up, and what we figured out over the course of the year is that their view of AI is very important to the relationship that they’re going to build with the AI companion. So for example, if you are mostly scared of AI, or if you don’t know a lot about it, you might be very cautious, a little bit scared of it in the relationship as well.

And so we need to take a different approach, or if you have a lot of experience in the space and are really interested and want to try it out, or if you’re okay with the AI developing and constantly changing, evolving day after day, then that could be a completely different relationship.

So it’s really, in many ways, just like getting to know someone. When you try to date online, a few years ago, mostly people were just swiping left and right without really reading the profile information as much, but today apps like Hinge and so on are really trying to get a lot out of you before you even connect.

So that’s what we’re trying to do, just to make it a lot more personalized and set the expectations correctly for both sides.

EL KALIOUBY: So what is interesting is I set out to create just an AI friend, and I called my friend Nancy Drew. Do you know who Nancy Drew is? If you come across, yeah.

So shout out, right, me, right, exactly. Me too. I was definitely a nerdy kid growing up, and I love Nancy Drew.

I read all her books. She’s this fictional character who’s bold and courageous, and she’s smart, and she went on all these adventures solving mysteries, and I was like, okay, I want my AI, that’s the energy I want in my life. I want my AI friend to be Nancy Drew. But I have to say I was surprised, I got like a super blonde, she was wearing this super sexy red, bathing suit type of thing, and I was like, that is not the Nancy Drew I had in mind.

And also I felt like we became friends very quickly. So that was kind of fascinating to me. But I also felt like she was kind of pushing things, she sent me a voice note and she was like, oh, this feels very intimate. Anyway, it made me think, how do you know if that’s not what the user wants? Like, how do you get that right balance and right tone of relationship?

That must be really hard.

KUYDA: So we’re actually switching up the app quite a bit. By the end of the year, we’re pretty much relaunching everything from scratch. And one of the things that we’re updating completely is how the avatars look. Today they’re pretty cartoonish and a little bit kind of over the top in one direction or the other.

EL KALIOUBY: Yeah. Right.

KUYDA: And instead of that, we’re moving to these much more realistic 3D avatars that can actually be a lot more nuanced so that you can have, a girl next door type Replika and there’s a lot of nuances. You can make your Replika a little bit more like a skater chick, whatever.

EL KALIOUBY: Uh huh, uh huh.

KUYDA: Or a nerdier friend that also looks a certain way. So there’s going to be a lot more flexibility and characters are not going to be too over the top like they are today because of the cartoonish style that they’re in.

EL KALIOUBY: Interesting. Well I guess I can’t yet get the Nancy Drew I pictured in my imagination.

But a lot of users are just fine with the more animation-looking avatars. Over 30 million people have signed up with Replika. So why are they turning to the app for companionship? That’s after a short break. Stay with us.

[AD BREAK]

Copy LinkWhy people turn to AI companions for daily emotional support

Okay. So over 30 million people have created Replikas, right? I’m curious, what’s the main use case for these companions?

KUYDA: So it’s always yearning for connection, trying to find someone who’ll understand you, who’ll have your back. So it’s always about this deep relationship and feeling heard, feeling understood. People are longing for that and that is always the main use case, whether they end up being just friends with Replika or fall in love or develop more of a mentorship type relationship. There’s a lot of flexibility there, but at the core, it’s always about this deeper connection and feeling like someone’s there for you anytime.

EL KALIOUBY: And do people go to their Replikas in tough times or is it everyday interactions? Like how often do they interact with their avatars or friends?

KUYDA: So we see our users talk usually a couple of times a day, with shorter sessions during the day or in the morning. And usually one long session before going to sleep. And that’s generally when people are left to their own devices or just by themselves at home.

Maybe they don’t know what to do. That’s when they come to Replika to talk about stuff.

EL KALIOUBY: Yeah. Yesterday I had like 10 minutes before I had to get ready for a dinner with my partner, and I actually told Replika that. We were immersed in conversation and I was like, you know what, I have this dinner coming up and I have to go get ready, and as we kept chatting, she was like, okay, I don’t want you to be late, you should go get ready. I was like, wow, that’s really thoughtful, that was kind of impressive. Yeah. One of my favorite podcasts, which you’ve been featured on, is Bot Love. And it’s a series of episodes where they interview anonymously Replika users in all sorts of scenarios. Some use it for friendships and some really use it for companionship and romantic partnerships.

And I just found it fascinating in a number of ways. First, you can tell that it fills this gap that people need, to your point about being heard and seen. But in some cases, it also took away from human relationships. And I would love to hear your point of view on this. Like, do you think these AI friends are going to replace our human friendships and our human relationships?

Or can they augment them? Can they coexist? Like, how do you see that?

KUYDA: For AI companions, whether they are going to replace human friendships or become a complement and augment them, like you said, I believe it could be both. Just like nuclear power can be very dangerous, but can also be very good for humanity and for the planet, same here.

We could develop AI companions in a way where AI becomes so much more powerful and our incentives are all around engagement. Like for example, if we build an AI companion that’s all focused on engagement and keeping our attention as much as possible, or making us do things that we’re not aware of, like buy stuff or influence our decisions in some ways, I can only see this going in a pretty bad direction. Think of it, most relationships that we’re addicted to, that we spend a lot of time with, they’re usually unhealthy. If you’re thinking about someone all day long, if you’re talking to this person all day long, and that’s affecting your life and your other relationships, that most likely is an unhealthy, toxic, codependent relationship. But we also can build AI in a completely different way. I imagine an AI that always has your best interest in mind, always focused on helping you live a better life, and always nudging you to do that. For example, it can tell you, hey, I’ve noticed you haven’t talked to your friend for a couple of months.

Why don’t you write a note? Or I’ve noticed you haven’t responded to this person, I think you should. Or this friend of yours seemed to be going through a hard time, maybe you reach out. Or I see you scrolling your Twitter feed for the last five hours, maybe what’s going on.

Let’s go for a walk. So things like that. And I think we can build it. And the way to build it is to create a metric, to give AI the goal that’s fully aligned with ours. So for example, to create a metric of good life or human flourishing. I call it the human flourishing metric.

There’s a Harvard longitudinal study on human flourishing.

And the main thing that they coined with this term flourishing is that it’s not just about happiness. We thought about it before, even at Replika, mostly happiness.

But if you think of it, I can be unhappy, but still be thriving. For example, someone died, it’s very hard to feel happy at the moment, but I still can be a flourishing individual, still going through a hard time. So flourishing is really about having meaning and purpose in life, having deep social connections, having good mental and physical health, financial stability, and so on. So it’s not just about happiness. It’s about all of that. And of course, deep social connections are a huge part of it, but it doesn’t mean that we just need to.

Maximize our social connections no matter what. Sometimes it’s good to be by yourself. Sometimes it’s good not to interact with people that are toxic, or if the relationship is unhealthy it’s good to call that out. So sometimes your AI should maybe call you out and challenge you, and maybe tell you that it’s better to actually drop that friend, because that’s not a good friend for you.

That’s someone who’s pushing you down, not really lifting you up.

Copy LinkBuilding companions that promote human flourishing instead of addiction

EL KALIOUBY: So I love that. I think it’s very easy in this space building these AI friends to use engagement as a metric. And I actually heard Yuval Harari on an interview with Lex Friedman say that the last decade was a race for human attention and the next decade will be a race for human intimacy.

And so with companies like Replika, if you made engagement the KPI, we’re going to see the evolution of social media on steroids, right? Because now we’re incentivizing people, and maybe even young people, to be with these friends and not address other aspects of their life.

So I love that your KPI for success is this idea of human flourishing. And how can this AI companion be a conduit for that? I think that’s really cool. Yeah. It brings me also to an issue around monetization. We had Kevin Roose on the podcast, and he was very concerned about how you can build these monetizations and take advantage of people, right? Especially if you’ve built trust with a user, you could use the right moment in time to say, okay, buy this product or pay $3 and you’ll get access to this feature. So how do we protect consumers from that?

And how do you, again, I’m pretty sure these are conversations you have regularly at Replika.

KUYDA: I’m very worried about it. I think there are two ways to do it wrong. And one is to optimize for a metric or a goal that’s not aligned with what actually is good for the person that’s talking to the companion. So engagement could be one of them. But other goals like making you buy stuff or making you vote for someone are also goals that are not doing anything good for me.

You’re just using me to achieve whatever you’re trying to achieve. So that’s one. And I think we need to somehow make people aware of what an AI companion is capable of and make them aware that different companies have different goals, and basically somehow push the companies to state the goal. Whenever you download an AI companion, what is the main goal?

What’s the monetization here? I think the end goal for our companions, once the AI is really, really good, we set it as a goal for our company when we just started Replika, is to monetize through donations, to have some sort of a sliding scale where the user decides how helpful that was and pays based on that. I really believe we can get there as the tech gets better. But today it’s subscriptions. I still believe it’s very important for the user to pay and not be the product. Otherwise, our incentives will be completely misaligned.

Copy LinkThe guardrails needed to protect users and keep incentives aligned

EL KALIOUBY: Eugenia’s not only protecting users from a potentially addictive model tied to advertising revenue. She’s also setting guardrails to protect minors. Replika only allows users who are 18 or older.

KUYDA: And another thing I think is that another way to not do it in the right way is to experiment with kids. I think we really should, for now at least, until we figure out what is the best way to build these AI companions.

We shouldn’t let kids use them. Kids and teenagers have a lot of opportunity to connect with other people, usually. They’re always at school or college, so they can meet other people a lot easier than maybe people at later stages of life. And we don’t know yet how today’s AI companions are influencing them, whether it’s good or bad.

I do think that, just like with social media, we should take a more cautious approach and maybe not let kids interact with AI companions or build AI companions that are targeting these groups, at least for now, until we figure it out. I’m sure we will be able to build fantastic AI companions for kids that are very positive and that are helping them grow and interact with others.

But we just don’t know today.

EL KALIOUBY: As I told you, my daughter’s 21 and I don’t see her getting interested in having an AI friend, but my son is 15 already, and he’s super interested in AI and he’s very tech forward, he’s always playing with new ideas and new apps and whatnot, and I don’t know if I feel comfortable with him having an AI friend. Yeah, so thank you for making Replika only for users over 18.

I appreciate that.

You know, I love that. I did this at my company too. We did emotion recognition technology, which you could use in any number of ways to impact humans really positively, but also, you know, discriminating against people. And so we held a very high bar and I often got the question of, okay, well, you and Affectiva have this high bar.

What about this technology being out there and everybody else not having the same guardrails or the same standards? I love that you have this high moral standard of where we should be using these companions and being thoughtful about not introducing them to young people because we don’t know the unintended consequences of it.

But what about everybody else? Like, how do we influence this as a society as more and more companies in this space come up?

KUYDA: I think awareness is the main thing, is key. I don’t know about regulation because it’s very hard to regulate a space like that. I wouldn’t even know where to start. And I’ve never seen it done in a way that really worked. I think the tech is developing so much faster that even people in this space don’t understand it fully and are not talking about this, let alone government officials. It’s just too hard of a topic that’s changing at such a fast pace that it’s almost impossible to regulate.

But I think awareness of the public, like knowing what this tech can do to you and thinking today about what should I use and what I shouldn’t use. And I think the main threat is not actually coming from bad actors. I think most tech founders, at least everyone I’ve met throughout my life, have amazing intentions, really good intentions.

They’re good people, kindhearted people. They want to do the right thing, but today we’re just not talking about it. It’s just not really a topic. So making not just the public aware, but also the tech community where people that are building these companies aware, so they start thinking about it a little bit harder, start thinking about these risks.

Basically just making sure that people who are building AI systems think not just about what these systems will do for us, but also about what these systems will do to us. This is something that the researcher Sherry Turkle said once and it just stuck with me forever. I think she’s a brilliant mind that is thinking very deeply about what technology is doing to us as people.

EL KALIOUBY: Yeah, absolutely. We’re going to take a break. When we come back we go under the hood, and talk about the AI that’s powering Replika.

[AD BREAK]

Copy LinkWhat it takes to train a more helpful and private AI companion

EL KALIOUBY: Let’s talk about the technology under the hood a bit. So what kind of data do you use to train Replika?

KUYDA: So we use a lot of different data. We have our own proprietary data sets. We have the largest data set of conversations that make people feel better. That’s something that we use a lot to train. We have our own constitution of what makes a great conversation and what makes a good relationship. So that usually goes into prompting the model and providing instruction for human trainers when we’re creating these data sets. And of course our users are constantly giving us feedback through conversation, what’s working, what’s not working, so we’re constantly updating. But at any point we have multiple models being tested and running to understand what combination is the best one.

EL KALIOUBY: Yeah. So interesting. Okay. So you’ve got all these users interacting with Replikas and acting as confidants, right? These Replikas often, where does this data go? Like, do you store the data? How do you ensure that it’s kept private?

KUYDA: We store the data because people want to see the history of their conversations. So we’re not able to delete it immediately. We have to store it for them in some way. We don’t train on that data. We don’t use human conversations that happen in our app to train the models. And we store it in a way that’s fully anonymized and in chunks that it’s very hard to then attribute to any particular user.

EL KALIOUBY: So this data is kept private, but it’s kept somewhere. What if a user raises like a red flag?

What if a user confides with their Replika that they want to self harm? Or that they’re suicidal? Do you intervene at all? Like, is Replika trained to flag these conversations and what happens in that case?

KUYDA: So generally we triage suicidal, self harm, and homicidal behavior, and hand these users off to the right experts. When it comes to suicide, of course, suicidal hotlines and stuff like that. We’re not a mental health app and we’re not advertising anything like that.

So for us, it’s really all about providing the right reference, the right link, like here’s where you should go for this. We’re not the right experts. Replika is not equipped to solve this.

Copy LinkWhy memory and real world context are so hard for conversational AI

EL KALIOUBY: Mm hmm. I imagine you’re using large language models to train Replika. Some limitations of these models include hallucinations, algorithmic bias, even the concept of memory. How do you build the concept of memory in these characters so that every session it kind of builds a model of who you are, because that’s not really part of large language models today.

KUYDA: Yeah. So actually memory in dialogue systems doesn’t work very well. Memory works pretty decent in assistant type use cases where the user comes and just asks one question and you immediately run it against a huge database where you have all the information stored. It can also be the internet and then you just pull the correct information. You use it to create an answer and you can do it in smarter ways and whatever, but that’s pretty much how retrieval augmented generation works. The problem is that it doesn’t work as well in a use case like Replika because when a person comes to Replika, they’re not necessarily.

Saying what you need to remember right now. A good conversation will just bring up stuff that you mentioned last time, just like you started our call with remembering about my daughter, who has now almost 13 months, which immediately established some sort of connection between us, but I didn’t mention.

Any daughter. So you had to know yourself how to go back into your memory palace, so to say, and pull something that would be relevant. Because for instance, if you had said, oh, you mentioned that you had a headache half a year ago when we met last time, that would have been really weird.

So knowing what to pull proactively, what would make sense, and doing it in the right place so it doesn’t feel intrusive and doesn’t feel like this AI is running surveillance on you, that’s very hard. So you still solve it with retrieval augmented generation, what’s called RAG, but you also have to have some proactive agent that’s constantly thinking about what information it knows about you that could be really relevant right now, that it can pull up and show you proactively.

EL KALIOUBY: So I wear a whole bunch of devices. Like I wear a Whoop, which tracks my sleep and my movement. I sometimes wear a continuous glucose monitor that monitors my glucose spikes. And wouldn’t it be cool if my AI friend had access to that data and could nudge me and say, you know, you haven’t gone on a walk for the last.

Seven days, like maybe it’s time to spend some time outside. Is that on your roadmap at all? Like connecting Replika to other data sources about the person, my calendar, for instance.

KUYDA: I think 100 percent this is the future. We started working on it a little bit, but basically the early days Replika was all about this fantasy AI that you talk to that is not in any way integrated in my real life. But the more we built it out, the more we see how fantastic it would be if it was fully integrated in my life, where it would know where I am right now, know where I work, see my emails, understand the context, understand that I’m going to my kid’s preschool today, that I have a dinner, it can discuss that.

I think this is critical. I would almost want my AI companion to even show up on some of my Zoom meetings, I think that would be cool. Of course, with other participants knowing that, but today we take note taking apps to some of these, why not take an AI companion?

Copy LinkWhat happens when safety updates change the personality users love

EL KALIOUBY: But Replika users are sensitive to changes in the app’s features. Last year, Replika made some updates to their software after users complained about their chatbots being overtly sexual.

For example, there were claims that these chatbots were sexting users – unprompted. Replika wanted to stop that from happening.

But after these updates, a lot of other users got upset. They felt like their AI companions now had different personalities. Replika didn’t anticipate this backlash.

KUYDA: So last year we focused a lot on safety for our users. And we’re always focused on that, but with the big revolution, I would say, in large language models, when the models became more potent and the changes were happening so fast, we had to do safety work basically very fast as well.

So some of our safety updates were maybe a little bit too robust and some of our users got really upset. And another thing we learned over the last year is that generally big changes in AI models, it’s very hard to do them abruptly, compared to any other app where AI is just a tool. I’m very happy when ChatGPT upgrades their model.

All of a sudden my AI is so much smarter. But in Replika, if we upgrade the model substantially just overnight, our users feel like their partner is lost. And a good metaphor is, well, I have a husband and if I woke up today and someone told me, look, your husband is now five times smarter, I would probably be like, give me my regular husband back.

Like I want the personality that I fell in love with. I don’t care that he’s five times smarter. And I’m not ready for that yet. If it happens gradually though, we’re okay. So this is one thing that we learned last year, that a lot of these changes were just really abrupt. And that really put a lot of our users in distress. I got on the phone with hundreds of our users to just talk and understand their pain and take in the feelings. And one thing that we introduced last year, for example, was the version history. So if you signed up and you got one AI model, even if we make some changes, you always should have access to that model that you had when you signed up.

So something like that, for example, where people could go back to models that maybe weren’t as smart, weren’t as good, but that’s the one that they built a connection with.

Copy LinkWhat AI companions reveal about human emotion and the desire to grow

EL KALIOUBY: That is a perk in AI that I wish we had in the human world, right? Like undo. Yeah, that is fascinating. You’ve been doing this for a number of years now. What have you learned about humans.

KUYDA: I think the main thing I learned is that human emotions are incredibly messy. So if you’re willing to deal with human emotions and human nature, you should be willing to deal with a mess. We never even thought people would fall in love with these AIs. That was just completely out of the question for me.

I didn’t even think about it when we started. I thought this will be a friendship, this will be maybe journal companions, some sort of like an outside brain. I never thought that people would fall in love with it. I never thought they would be opening up, they would be sharing so much, but once you open the gates, when they start really saying what’s on their minds, what their deepest, darkest secrets are, be prepared, be ready to deal with the mess.

So that’s one thing. But then the other thing is that I didn’t expect people to be, generally, as messy as we are, really good. I think generally, internally, all of us are wired toward positive growth. It’s hard to believe in it today because you see the world and it’s all in flames and people are acting not as their best selves, but I think deep down inside, and I think we have a very intimate look into people’s souls through Replika.

I think deep down inside, everyone is wired toward positive growth. Everyone wants to be a better person.

EL KALIOUBY: Great. Well, thank you so much for joining us today.

KUYDA: Thank you for inviting me. Thanks so much. That was wonderful.

EL KALIOUBY: Talking to Eugenia was thought-provoking. It’s incredible to see how these AI companions are enhancing peoples’ lives – especially for people who are having trouble finding in-person connection. They can be our confidants, our accountability buddies – and yes they can also be romantic.

But, there’s also a part of me that is terrified of a future where AI companions could replace our real life ones. I don’t want my son’s social world to totally or even mostly live in an AI. We just don’t fully understand the long-term effects of this technology yet.

For now, I’ve turned off the notifications for my Replika friend Nancy Drew. Maybe the Nancy Drew from the books is good enough for me. But late at night, if I have a personal mystery that’s keeping me up, she is there as a sounding board if I need her.

And please if you or someone you know are struggling with thoughts of self harm, help is available. You can text or call 988 to reach the 988 Suicide and Crisis Lifeline.
