Transformer Ceiling: 31% Max – Guo's Thesis Kills the Scaling Pitch – Neural Toons comic

“When the proof of impossibility arrives, the pitch shifts from 'more' to 'enough.'”

The story behind the toon

What happened: When the proof of impossibility arrives, the pitch shifts from 'more' to 'enough.'

This Neural Toon is based on the story “The Deterministic Horizon: Impossibility Results as Design Specifications for Trustworthy AI Systems”.

Comic transcript

Panel 1 – Alex: Our transformer hits 28%. More compute gets us to 40%.

Panel 1 – Priya: Scaling won't save you. I've seen this movie.

Panel 2 – Alex: Guo? Never heard of him.

Panel 2 – Priya: Deterministic Horizon: 12 architectures, ceiling 19% to 31%.

Panel 3 – Alex: Trustworthy? That kills our valuation.

Panel 3 – Priya: Your 40% goal is impossible. Time to pivot to trustworthy AI.

Panel 4 – Alex: And our hidden data pipelines?

Panel 4 – Priya: Guo also designed 16 specs. They'll reshape safety audits.
