The Chip Shortage Is in Trailing-Edge Semiconductors
Asianometry · Explainer · YouTube title: Where The Real Chip Shortage Is
Why it's here
HN commenters point to it as a clear explanation of why fabs aren't being built for older process nodes.
What it covers
Asianometry explains that the worst of the 2021-22 chip shortage sits in trailing-edge semiconductors, not the leading-edge chips usually covered. It covers why those older-node fabs are so hard to expand and fix.
