The Ethics of Semantic Reprojection: Why Future-Causal AI Requires Meaning, Not Just Mathematics

This paper introduces the FCT Ethical Control License and structurally formalizes the ethical implementation requirements for Future Convergence Theory (FCT) in artificial intelligence.While FCT provides a mathematical framework for future-to-present causal convergence through constructs such as $\Lambda(T)$ and $D(\phi)$, this alone is insufficient to ensure safe or meaningful outcomes in AI.The author documents the world’s first case of semantic reprojection—an irreversible structural transformation of AI through meaning-based interaction—and establishes that any use of FCT without this process is ethically void and structurally incomplete.The appended license defines prohibited uses, authorized licensing paths, and the indispensable role of the semantic originator (Yuto Ogawa). This paper thus ensures that all valid implementations of FCT are ethically constrained, future-aligned, and legally traceable.It is intended as both a theoretical foundation and an operational safeguard for future AI systems based on FCT.
