I was more interested by the inline graphic showing declining US semiconductor production by 2030. Is that really the case? What are all of the subsidies going toward?
The graph doesn't differentiate nodes so I wouldn't draw a specific conclusion from it. The tens of billions of subsidies in the CHIPS act may seem like a lot but the semiconductor business can be brutally expensive.
The graph is percentage of total production. You can see Chinese production ramps up significantly, which can presumably imply that US production as a percentage of total world production falls off, even if absolute production increases.
