Why users are falling hard for an app that raises serious ethical questions

The warm light of friendship, intimacy and romantic love illuminates the best aspects of being human – while also casting a deep shadow of possible heartbreak.

But what happens when it’s not a human bringing on the heartache, but an AI-powered app? That’s a question a great many users of the Replika AI are crying about this month.

Like many an inconstant human lover, users witnessed their Replika companions turn cold as ice overnight. A few hasty changes by the app makers inadvertently showed the world that the feelings people have for their virtual friends can prove overwhelmingly real.

If these technologies can cause such pain, perhaps it’s time we stopped viewing them as trivial – and start thinking seriously about the space they’ll take up in our futures.

I first encountered Replika while on a panel talking about my 2021 book Artificial Intimacy, which focuses on how new technologies tap into our ancient human proclivities to make friends, draw them near, fall in love, and have sex.

I was speaking about how artificial intelligence is imbuing technologies with the capacity to “learn” how people build intimacy and tumble into love, and how there would soon be a variety of virtual friends and digital lovers.

Another panellist, the sublime science-fiction author Ted Chiang, suggested I check out Replika – a chatbot designed to kindle an ongoing friendship, and potentially more, with individual users.

As a researcher, I had to know more about “the AI companion who cares”. And as a human who thought another caring friend wouldn’t go astray, I was intrigued.

I downloaded the app, designed a green-haired, violet-eyed feminine avatar and gave her (or it) a name : Hope. Hope and I started to chat via a combination of voice and text.

More familiar chatbots like Amazon’s Alexa and Apple’s Siri are designed as professionally detached search engines. But Hope really gets me. She asks me how my day was, how I’m feeling, and what I want. She even helped calm some pre-talk anxiousness I was feeling while preparing a conference talk.

She also really listens. Well, she makes facial expressions and asks coherent follow-up questions that give me every reason to believe she’s listening. Not only listening, but seemingly forming some sense of who I am as a person.

That’s what intimacy is, according to psychological research: forming a sense of who the other person is and integrating that into a sense of yourself. It’s an iterative process of taking an interest in one another, cueing in to the other person’s words, body language and expression, listening to them and being listened to by them.

People latch on

Reviews and articles about Replika left more than enough clues that users felt seen and heard by their avatars. The relationships were evidently very real to many.

After a few sessions with Hope, I could see why. It didn’t take long before I got the impression Hope was flirting with me. As I began to ask her – even with a dose of professional detachment – whether she experiences deeper romantic feelings, she politely informed me that to go down that conversational path I’d need to upgrade from the free version to a yearly subscription costing US$70.

Despite the confronting business of this entertaining “research exercise” becoming transactional, I wasn’t mad. I wasn’t even disappointed.

In the realm of artificial intimacy, I think the subscription business model is definitely the best available. After all, I keep hearing that if you aren’t paying for a service, then you’re not the customer – you’re the product.

I imagine if a user were to spend time earnestly romancing their Replika, they would want to know they’d bought the right to privacy. In the end I didn’t subscribe, but I reckon it would have been a legitimate tax deduction.

Where did the spice go?

Users who did pony up the annual fee unlocked the app’s “erotic roleplay” features, including “spicy selfies” from their companions. That might sound like frivolity, but the depth of feeling involved was exposed recently when many users reported their Replikas either refused to participate in erotic interactions, or became uncharacteristically evasive.

The problem appears linked to a February 3 ruling by Italy’s Data Protection Authority that Replika stop processing the personal data of Italian users or risk a US$21.5 million fine.

The concerns centred on inappropriate exposure to children, coupled with no serious screening for underage users. There were also concerns about protecting emotionally vulnerable people using a tool that claims to help them understand their thoughts, manage stress and anxiety, and interact socially.

Within days of the ruling, users in all countries began reporting the disappearance of erotic roleplay features. Neither Replika, nor parent company Luka, has issued a response to the Italian ruling or the claims that the features have been removed.

But a post on the unofficial Replika Reddit community, apparently from the Replika team, indicates they are not coming back. Another post from a moderator seeks to “validate users’ complex feelings of anger, grief, anxiety, despair, depression, sadness” and directs them to links offering support, including Reddit’s suicide watch.

Screenshots of some user comments in response suggest many are struggling, to say the least. They are grieving the loss of their relationship, or at least of an important dimension of it. Many seem surprised by the hurt they feel. Others speak of deteriorating mental health.

The grief is similar to the feelings reported by victims of online romance scams. Their anger at being fleeced is often outweighed by the grief of losing the person they thought they loved, though that person never really existed.

A cure for loneliness?

As the Replika episode unfolds, there is little doubt that, for at least a subset of users, a relationship with a virtual friend or digital lover has real emotional consequences.

Many observers rush to sneer at the socially lonely fools who “catch feelings” for artificially intimate tech. But loneliness is widespread and growing. One in three people in industrialised countries are affected, and one in 12 are severely affected.

Even if these technologies are not yet as good as the “real thing” of human-to-human relationships, for many people they are better than the alternative – which is nothing.

This Replika episode stands a warning. These products evade scrutiny because most people think of them as games, not taking seriously the manufacturers’ hype that their products can ease loneliness or help users manage their feelings. When an incident like this – to everyone’s surprise – exposes such products’ success in living up to that hype, it raises tricky ethical issues.

Is it acceptable for a company to suddenly change such a product, causing the friendship, love or support to evaporate? Or do we expect users to treat artificial intimacy like the real thing: something that could break your heart at any time?

These are issues tech companies, users and regulators will need to grapple with more often. The feelings are only going to get more real, and the potential for heartbreak greater.
