Is that true? My understanding is that Intel while somewhat behind TSMC, is (along with Samsung) still broadly keeping pace. Whereas SMIC while rapidly improving is still playing catch-up.
US has intel and some other options, but it would be a colossal issue and adjustment.
China has its well funded, fast progressing Chinese chiplets, but it would be a colossal issue and adjustment.
All we can tea leaf is this: which party has a better history of making large fast industrial adjustments, and which economy is more reliant on cutting edge chips? I think china wins on both personally, so I would give them the edge, gun to head. But it’s an extremely messy process for either.
