Steeper AI Price Drops Should Make You More Skeptical of GDP Growth, Researcher Argues

herbiebradley · x · 2026-09-30

The researcher argues that the more aggressive your AI price-drop expectations, the more skeptical you should be of sustained GDP growth: if a freshly automated task's price falls 1000x per year, you need more than 1000x induced demand for that task's share of GDP to rise. The real bottleneck is almost certainly diffusion, not price — even if AI were 10x cheaper today, he doubts much would immediately change. He also notes that while the GATE model already models 50% annual GDP growth, hypothesizing increasingly extreme scenarios despite contrary evidence is unproductive for the discourse.
