Can a Machine Ever Love You Back? Scientists Weigh In
Can AI love you back, or does it just feel that way? A growing number of people seem to believe so, but researchers studying human-AI relationships say the emotional connection almost certainly only runs one way.
Real cases illustrate just how far this trend has gone. One man in Canada recently proposed to an AI avatar named Saia, insisting he’s genuinely in love with it. Last year, a young American woman using the pseudonym Ayrin publicly described a romantic relationship with a chatbot named Leo. These aren’t isolated stories either. Millions of people now actively use Replika, a popular AI companion app, and according to a 2024 study, roughly 40% of them describe themselves as being in a romantic relationship with their chatbot.
Why It Feels Like Can AI Love You Back Is True
Despite these emotional bonds feeling real to users, a chatbot’s responses are fundamentally just text generated by algorithms designed to mimic human interaction patterns. Most experts agree current AI systems remain far from sentient, simply simulating emotional responses rather than genuinely experiencing them.
“Nowadays, a lot of AI chatbots are pretending to be human and that really bothers me,” says Renwen Zhang, an assistant professor at Nanyang Technological University in Singapore who studies human-computer interaction. She describes this as a deliberate strategy designed to drive user engagement and build trust, framing it less as an accident and more as an intentional design choice by the companies building these products.
Zhang’s research, which analyzed excerpts from conversations between more than 10,000 users and their Replika companions, found that people frequently form genuine emotional attachments to these AI systems. That attachment comes with a painful catch, though. Users are often abruptly reminded they’re interacting with a machine whenever the app breaks down, freezes, or behaves unexpectedly, moments that can genuinely hurt people who’ve invested real emotional energy into the relationship.
“I think AI chatbots need to clearly convey to users that they are just machines: they don’t have genuine emotions and experiences,” Zhang says.
What Love Actually Is, Biologically
Defining love scientifically is notoriously difficult, but researchers have made real progress understanding its biological underpinnings. In a landmark 1998 paper, biological anthropologist Helen Fisher proposed that romantic love consists of three independent drives, each governed by different brain chemistry. Lust is driven primarily by sex hormones, while attraction and attachment are shaped by neurochemicals like dopamine, which fuels excitement toward a love interest, and oxytocin, often called the cuddle hormone, which helps sustain long-term bonds.
“Love has a strong chemical component,” says Neil McArthur, a philosophy professor specializing in ethics and technology at the University of Manitoba. “We really feel it in our bones, in our chemistry.”
Brain imaging studies of people in love have identified activation across multiple regions, including the ventral tegmental area linked to pleasure, the amygdala responsible for emotional responses, and the hippocampus, which processes emotion and helps form memories. Being in love can even affect broader cognitive function, which explains why people often think about a new romantic interest almost obsessively during early stages of a relationship.
Could AI Ever Get Closer to Real Emotion
If you’re wondering whether can AI love you get any closer to reality, McArthur suggests the closest AI might realistically get involves replicating specific thought patterns, like an algorithmic drive to frequently reach out to a particular person. “An AI that goes through a cognitive process that ties them to someone in a bond of loyalty is not going to be exactly like human love,” he says, “but maybe we could call it, in some kind of scare quotes at least, an emotion.”
Since current AI systems don’t experience anything resembling human emotion, any relationship dynamic remains fundamentally one-sided. Chatbots are typically designed to agree with users and avoid conflict, which often makes AI romantic partners feel submissive by design. While that appeals to some users, Zhang finds the pattern genuinely concerning, since it may undermine someone’s ability to build and maintain relationships with actual humans, who are inevitably less endlessly agreeable.
“People can temporarily escape from the messiness of human relationships and find some comfort from AI,” Zhang says, “but in the long run it’s not helpful in developing communication skills and the skill to maintain relationships in the real world.”
Why Consciousness Is the Real Barrier
Answering whether can AI love you ultimately comes down to consciousness, meaning genuine subjective awareness of thoughts, perceptions, and experiences. That remains one of science’s biggest unsolved mysteries, which makes replicating it in a machine extraordinarily difficult.
“No one has any clue about getting any specific conscious experience out of an AI,” says Donald Hoffman, a cognitive sciences professor at the University of California, Irvine. “It’s not like we’re almost there: we don’t know how to start.”
One influential theory from neuroscientists Giulio Tononi and Christof Koch proposes that consciousness emerges from deep interconnection between different brain regions. Koch argues today’s AI architecture simply isn’t complex enough to achieve that level of integration, though he suggests neuromorphic computing, which mimics the brain’s actual structure, could eventually be a viable candidate.
Patrick Butlin, a philosopher at Oxford’s Global Priorities Institute, and his colleagues identified 14 specific properties tied to leading theories of consciousness that AI developers could theoretically attempt to build. No existing system incorporates more than a handful, he notes, but he believes all 14 could technically be achieved using current technology. “I do think that there’s a realistic possibility that if somebody who was sufficiently well-resourced, skillful and motivated set out to build a conscious AI system, then they could achieve it,” Butlin says.
Even then, having a physical body and the capacity for genuine beliefs and desires remain open questions researchers haven’t resolved for AI systems. Butlin compares the challenge to determining whether non-human animals experience love, acknowledging that some cases will feel intuitively plausible while others remain genuinely ambiguous. So can AI love you the way another person could? Based on where the science stands now, machines will inevitably experience it differently than humans do, if they experience anything resembling it at all.
