Yes, I understand that more mining could be done, but what I was saying is that I don’t think it could be sustained to the level of silicon. Bismuth is a rare mineral, and 100 times more expensive than silicon.

Not an expert, but high purity bismuth seems 6x more expensive than high purity silicon. I could be wrong.

they would only be able to tackle a very small fraction of that.

It would be for ultra premium performance chips, which China has a low share currently.
