We present the Principle of Latent Extremophile Survival (PLSE), the third principle of the Law of Semantic Tolerance. PLSE establishes that if a learning system works when it theoretically should not (ρ ≥ 1), then there exists a latent structure that makes it possible. We prove that ρ = 1 is a universal threshold and that “extremophile” systems survive because there exists a transformation φ that reduces ρ to learnable values. Rigorous tensorial derivations will be presented in a subsequent work.
