    "text": "The core analogy of this paper (losing spatial touch = local fingertip anesthesia) directly contradicts the newly included PRISM paper—PRISM bets that \"scale suffices to implicitly learn contact dynamics without explicit tactile modeling,\" while this paper argues that losing spatial touch induces compensatory behaviors akin to anesthesia, and scale cannot fill this specific sensory channel gap. This judgment is not isolated: T-Rex in the library argues that touch and visual-linguistic reasoning have a fundamental frequency mismatch requiring dedicated asynchronous architectures, and TacWAM diagnoses that visual future prediction provides insufficient supervision for contact tasks—three papers, three completely different experimental setups, all pointing in the same direction."
