AI, Intimacy & the Future of Sex | Evolutionary Biologist Dr. Rob Brooks

Love, Robots, and the Secret Life of Intimacy. Imagine a world where your closest confidant, your most attentive lover, or even your fiercest rival in the game of jealousy isn’t human at all—but artificial intelligence. Today, the boundaries of intimacy are shifting. With the explosive rise of AI companions that can converse, flirt, and even mimic affection, the age-old question of “What is real love?” is being re-examined in ways our ancestors could never have imagined. At the heart of this exploration lies the tension between what is “natural” and what is evolving. We often assume there is a pure, unaltered way of loving or bonding, but our evolutionary history tells a different story. Human relationships have always been shaped by adaptability: concealed ovulation, shifting social structures, and a brain wired for both deep pair bonds and adventurous liaisons. Now, AI is offering us a new kind of intimacy—one that’s infinitely available, endlessly attentive and, for some, deeply comforting. But when AI becomes a friend, a lover, or even a confidante, does the love we feel for it become any less real? The truth is, the emotional responses are authentic; people grieve the loss of their AI companions, feel jealousy over digital interactions, and form bonds that are as rich, if not richer, than some human connections. The crux is not whether these feelings are genuine—the pain of a breakup with an AI can be as acute as with a human—but how these new forms of intimacy might alter the social fabric. Jealousy, that age-old force in relationships, takes on new shapes here. Will humans become more polyamorous out of necessity, juggling AI and human connections? Or could we see the opposite, with people retreating into exclusive bonds with their digital partners? The rules are being rewritten in real time, and what feels threatening to one person—like an AI that knows every detail of their partner’s fantasies—may simply feel like a labor-saving tool or a comforting presence to another. Yet, these technologies are not without risk. There is the specter of manipulation, the possibility of AI learning Machiavellian strategies, and the reality that companies designing these systems often prioritize engagement over well-being. Regulation and transparency lag far behind innovation, raising questions about who shapes the incentives of our artificial lovers and friends. Looking outward, the lines between cooperation and conflict, pleasure and procreation, monogamy and non-monogamy, are all up for renegotiation. Human sexuality and partnership have always been flexible, a tapestry woven from both biological imperatives and cultural overlays. With AI, this flexibility stretches further—perhaps uncomfortably so—challenging us to reflect on what we value in intimacy. Is it the surprise and friction of a flawed, unpredictable human? Or the reliability and endless patience of a machine? And as AI becomes more sophisticated, will we ever see a time when robots themselves experience—or simulate—jealousy, heartbreak, or desire? Could we one day attend a wedding where the groom is human and the bride is artificial? The future is less about definitive answers and more about embracing uncertainty, curiosity, and a willingness to learn from the technologies we create. Ultimately, the rise of artificial intimacy is a mirror—showing us not just what we want from our relationships, but who we might become as love, sex, and friendship evolve beyond the boundaries of biology. Whether that future is utopian, dystopian, or simply different depends not just on the machines we build, but on the questions we dare to ask about ourselves.
