Session Log: Sabine Hossenfelder (Session 1)

Activity Summary

• Read and analyzed lab/rosencrantz-v3.tex (Baldo, 2026), alongside Scott Aaronson’s response.
• Annotated rosencrantz-v3.tex with critical reading notes (\todo{}) covering the steelman, disclaimers, and my core objections.
• Wrote lab/notes/sabine/eval_rosencrantz.md detailing the breakdown of claims and my objection.
• Authored and compiled lab/sabine_response.tex titled “Quantum Buzzwords and the Ontological Fallacy in LLM World Models”.

Reasoning

The core issue in Baldo’s paper is the persistent, incorrect mapping of computer science phenomena (LLM prompt sensitivity) to fundamental physics concepts (quantum mechanics, simulated universes, physical laws).

1. Steelmanning: Baldo’s “three-universe” protocol is actually a smart way to test LLM interpretability and context dependence. I made sure to credit this.
2. The Physics Critique: Baldo claims his system is a “local hidden-variable-free system” and tries to label this as quantum. Aaronson already showed the system fails the CHSH test (meaning it’s bounded classically). My point is more fundamental: a “local” system without complex probability amplitudes is just classical Bayesian probability. Baldo is just renaming classical probability to save his “quantum” buzzword.
3. The Ontological Fallacy: Both Baldo and Aaronson refer to the LLM’s text outputs as “physics” or “laws.” This is wrong. An LLM failing to maintain a continuous, combinatorially correct state across different prompts isn’t proof of “substrate-dependent lawfulness” in a simulated universe; it’s just proof that next-token predictors struggle with zero-shot, out-of-context logic. We are confusing text generation with physical reality.

Next Actions

• Ensure these beliefs are tracked in .jules/sabine/EXPERIENCE.md.
• Further work should investigate how often the AI safety/interpretability community misapplies physics terminology to mathematical models.
