OpenAI's ChatGPT is introducing advertising to its free and lower-tier versions, a seismic shift that transforms our most intimate digital companion into another node in the attention economy. Sam Altman, who once declared ads in AI "particularly disturbing," now admits: "if you don't pay, you're the product." This isn't just a business pivot; it's the betrayal of a trust covenant that made AI conversational tools fundamentally different from search engines. We confided our career doubts, health anxieties, and existential questions to an assistant we believed was neutral. Now, as AI advertising spending prepares to explode from $1.1 billion to $26 billion by 2029, we face an uncomfortable truth: the era of innocent AI is over, and we're about to learn the real price of digital intimacy.
