This industry turns a dollar into a hundred dollars. So why can it still not get a German mirror maker to expand?

Dwarkesh Patel, host of the Dwarkesh Podcast, relays the bottleneck argument made by Dylan Patel, founder of the semiconductor analysis house SemiAnalysis: even if AI progress and revenue hold up, the semiconductor industry cannot keep pace with the frontier labs' current compute expansion of more than 3x a year measured in watts, and by the end of the decade the binding constraint becomes wafer fab equipment, such as the extreme ultraviolet lithography machines made by the Dutch firm ASML. What is new is the question he asks next: if a few billion dollars of fab capital expenditure can generate hundreds of billions in end token revenue, why does that return still fail to get Zeiss to scale up the mirrors ASML's machines need? He leaves it unresolved (Dwarkesh Patel, 2026-08-27). Zeiss is the German optics firm that supplies those mirrors to ASML. ⚠️ Discount this relay three ways: we did not obtain Dylan Patel's own words, so this item is a relay; turning a dollar into a hundred is a figure of speech, not a computed ratio; and we have checked nothing about Zeiss's capacity or expansion plans. ⇒ The question transfers to any multi-tier supply chain: does my supplier get any of the return from my value chain? If not, why would they expand for me?
