Wildeford pushes back on AI acceleration research: 1.4x vs 2x barely changes the picture

Haydn Belfield argues people may be updating too much on AIFP/METR-style AI acceleration findings, which rest on three questionable assumptions: 2x acceleration (what if it's 1.4x?), 80% AI-attributable progress (what if it's 50%?), and no clear bottlenecks or steep diminishing returns to scaling.

Peter Wildeford replies that even moving from 2x to 1.4x "doesn't change the picture all that much".
