Semiconductor Chokepoint Mechanism

The claim - verbatim

Michael Darius Eastwood first published the 'Chokepoint Mechanism' - a specific naming and framing of concentrated advanced-chip manufacturing capacity as humanity's principal leverage point for AI governance before superintelligence - in the book Infinite Architects (ISBN 978-1806056200) published on 2 January 2026. Canonical numeric phrasing: 'a handful of companies control approximately 90 per cent of the world's most advanced chips'. Priority is over this specific naming and framing as an alignment-governance mechanism inside a broader Protocol, not over export-controls policy discourse generally.

Limits and citation guidance - what this claim does not support, and how to cite it

Limits. Substantial prior work exists in export-controls discourse (BIS October 2022 controls; CHIPS Act commentary). Do not use retired phrasings ('four companies control ALL advanced chips' or 'four companies control 100 per cent of advanced semiconductor manufacturing'), which the register flags retired.
