Sex, Love, and Robots: The Ethics and Emotions of Artificial Relationships

Humans have long been fascinated and unnerved by artificial intelligence. Recent developments have led to the emergence of AI therapists, emotional support animals, and even lovers. This raises deep existential questions about what it means to be human, such as: Can a robot ever really love us? Should humans have the right to be able to treat robots however they want? And will robots take over the world? Here’s a brief survey of some of the biggest questions about artificial intelligence, love, and the relationships between people and robots. 

In January 2019, Akihiko Kondo married a hologram.

Kondo, a 35-year-old schoolteacher in Tokyo, had been “dating” a holographic projection of an artificial popstar named Hatsune Miku for years. He finally tied the knot with her in 2018, albeit not legally, and Kondo swears that the love is real. “I’m in love with the whole concept of Hatsune Miku but I got married to the Miku of my house,” he said, referring to the $2,800 capsule that contains his “wife.” Apparently, Miku performs “wifely” duties like waking him up in the morning and telling him to go to bed. 

All this might remind you of another storyline, this time Blade Runner 2049. In that film, the protagonist K dates a holographic robot named Joi. Though she’s artificial, Joi (at least the version of her that we see in the film) eventually appears to develop feelings for K. 

Since it began in Philip K. Dick’s Do Androids Dream of Electric Sheep, the Blade Runner franchise has explored the boundaries between humans and robots, making the argument that even though robots might be different in origin from humans, their status as robots doesn’t necessarily negate their capability to love (or our ability to love them).

As Kondo’s “wedding” revealed, the future portrayed in Blade Runner 2049 has already arrived. We live in a world where robots can serve as companions, caregivers, and even lovers. These realities raise complicated questions about an already deeply complicated topic – love – but thinking critically about the ethics and science of robot emotions might just teach us a bit more about what it means to be alive.

Love in the Uncanny Valley: From Sex Robots to Holographic Wives 

Sex robots have been around for quite a while, if you count the sex dolls that date back to the 17th century. Flash forward a few centuries to 1997, and the first silicon mannequin sex robots were released by Matt McMullen. From there, the industry has continued to grow. Just recently, a Nevada brothel called Alien Cathouse made headlines for offering AI sex robots to global clients. For a cool $2,276, you can purchase a sex robot named Emma who is able to breathe, communicate, and remember details you tell her. Holographic wives (like Ahikiko Kondo’s) tend to go for around the same price. 

If given the choice, would you elect to have a robot companion? Most likely not. In fact, a recent survey cited in The Independent found that while 68% of participants thought robots could be helpful to humanity, only 28% said they’d want to have robot caregivers. So if you have an adverse reaction to the idea of having a robot wife or therapist, you’re not alone. 

“Evolutionary history has tuned us to detect minor distortions that indicate disease, mental or physical problems. To go after a human-looking robot or avatar is to go up against millions of years of evolutionary history.” – Psychologist Thalia Wheatley, Dartmouth College

In general, humans tend to react negatively to things that blur the lines between robotic and human characteristics. This is due to a phenomenon known as the “uncanny valley,” which refers to that peculiar feeling you get when you see a humanoid robot. Though it’s unclear as to exactly why we’re adverse to robotic creatures that resemble us (but not quite), some believe that evolution plays a role. 

In light of this, maybe the proper question isn’t whether robots can love us. Maybe it’s whether the average person will ever be able to truly love them. After all, isn’t true love what we’re all looking for? 

Robots of the Future: Emotions, Love, and Robot Relationships

The idea of having a submissive hologram for a spouse might appeal to a lot of people, but is that kind of love really love? What is love, after all? Well, that’s an age-old question (and a very good song). Of course, love is an emotion, but knowing that does not provide much clarity because there are many different theories about what emotion is. 

Psychology Today identifies three primary theories of emotion, which scientists are using to craft emotionally adept AIs. 

• The cognitive appraisal theory says that the emotions we feel are really judgments based on just how much events might contribute or harm our goals. If we use this definition of emotion, then robots could be technically capable of learning to “feel” if they were given precise objectives and programmed to act according to the effect of events upon those objectives. 

• Then there’s the physiological theory of emotion, which says that our emotions are based on hormones like cortisol that are triggered by certain events. Through this lens, it’s easy to imagine that an extremely advanced technology might be able to simulate the firing patterns of these hormones, but the human body is mind-blowingly complex, containing hundreds of millions of neurons. So, we’re a long way from the day that a robot can feel a jolt of dopamine when the pretty bot across the room smiles at them.

• Finally, there’s the theory that emotions are social constructions, created by preconceived notions and media. If this is true, then a robot that’s capable of reading and learning from human-made material could feasibly shape reactions to stimuli based on their existing knowledge.

In light of all this, it’s possible that a robot would be able to develop some semblance of the ability to express love. But is real love defined by care and reaction to stimuli and hormones, or is it something more, something divine or transcendent? And could an AI ever approximate that kind of true love? 

Roboethics: Should Robots Love, and What Rights Should They Have?

The question of whether robots can love usually arises in reference to how robots treat people. But if we’re speaking seriously about robots that can “feel” and “love,” even in a simulated context, we need to talk about how humans treat robots. Even if you don’t consider robot emotions and feelings to be real, there’s still something disturbing about the prospect of people keeping robotic slaves or using humanoid bots for their own purposes without any regulation. So, there is a threat that robot abuse could be a problem in the future. 

Dr. Hooman Samani thinks that robots can most definitely love. That’s why he’s invented a field called “lovatics,” which is intended to investigate human-robot relationships. Eventually, he hopes to develop robots that can “love and be loved” by humans.

Roboethics has existed since 1940, when Isaac Asimov developed his “Three Laws of Roboethics.” In order to address Asimov’s increasingly relevant questions, the First International Symposium on Roboethics took place in 2004, in Sanremo, Italy. Among other issues, the field of roboethics asks whether we’d want robots to think like humans, or like something different or better. Maybe we could get robots to think like us, but would we want them to? What if we could build on some of the flaws in the human mind, replacing selfishness with altruism and canceling out some of the suffering that plagues so many of us? 

“Humans are limited in the attention, kindness and compassion that they can expend to others, but AI-based compassionate robots can channel virtually unlimited resources into building compassionate relationships in the society.” – Amit Ray

After all, humans are often influenced by subconscious biases and deep-rooted wounds. Artificial intelligence has been shown to express the racist, sexist, or otherwise negative biases of the people who created them, and algorithms will always do this unless we engineer them to follow some sort of moral code. The need for ethics in Silicon Valley has often been emphasized, but it’s never been more important than with the question of artificial intelligence. 

Looking to the Future: Robot Rights Activism?

In spite of all the potential implications and pitfalls of human-robot relationships, there are still some who wholeheartedly believe that humans and robots can have real, fulfilling relationships – and they love to cite Blade Runner as an example. In the original film’s final scene, the robot named Roy Batty delivers his infamous “tears in the rain” monologue, which represents one of the film’s most striking and emotional moments. 

Watching Batty in that scene, it’s impossible to doubt that he really loves Pris, the robot he’s just lost. If a robot looked at me like that and delivered a similar monologue, I don’t know about you, but I think I’d be at the next Robot Rights protest.
