AI's Real Problem Is Illegitimacy, Not Hallucination 2 by JanusPater | 1 comments on Hacker News. The Core Problem of AI Is Not Hallucination — It Is the Lack of Execution Legitimacy Janus pater Introduction Most debates around AI today revolve around a false question: is the model smart enough, accurate enough? In engineering reality, the real question is never accuracy — it is whether the system is even allowed to act. 1. The Original Sin of the Predictive Paradigm: No Execution Legitimacy Modern generative AI fundamentally does one thing: predict the most likely next state in a probability space. Whether it predicts tokens, pixels, latent states, or so-called “world models”, as long as the output is probabilistic, it answers only one question: “What is most likely to happen?” In many real-world systems, however, engineering demands an entirely different question: “What is the only action that is allowed to be executed?” This is not an accuracy problem — it is a legitimacy pro...
