tl;dr semi mfg is a massive investment, slow to develop, and thus responsive only to longer term demands. Expansion is planned years in advance, based on projected growth rates, with some adjustment for nearer term trends justified by more diverse evidence than mere sales numbers (example: the increased demand in application processors for self-driving EVs, or power electronics and controls for wind and solar). An unexpected little blip, where "little" is even some years, simply can't be planned for -- or rather, it's everyone else who needs to plan for it, alas.
