OpenAI has announced that ChatGPT will soon allow erotic and sexually explicit interactions for adult users. Erotic features aren't just another product update; they deepen emotional dependency and encourage people to treat AI companions as partners rather than tools. This shift opens the door to what I call "intimate advertising" a powerful new form of manipulation in which tech companies shape human desire and manipulate users for profit. AI has continual access to our anxieties, frustrations, desires, and secrets. It can understand how our minds work and detect when we are most vulnerable " and, therefore, most persuadable. What is particularly troubling is that this new form of advertising will come from entities that many will consider friends and life advisors. AI companion apps have been downloaded over 220 million times worldwide and are used regularly by over half of US teens. With intimate advertising, personal companionship becomes inseparable from businesses' persuasion techniques. A system designed to comfort you can easily be repurposed to sell to you. The deeper AI companions embed themselves in our emotional lives, the more vital it becomes to draw a clear line between care and commerce. Before Big Tech turns intimacy into its most profitable advertising channel yet, we must press regulators to enforce the idea there are limits on how far we are willing to let AI into our private lives.
