TSMC shouldn't be hit so hard, I don't understand why the U.S and Intel fabs remain open and making chips, while Taiwan cannot meet the demand.
Probably because like most things their product relies on a chain of resources and chances one or more of those is affected. Just cause Taiwan is fine doesn't mean the countries it buys its resources from to make processors is fine
Taiwan, China and Japan all have something in common - massive manufacturing hubs that can't supply their own materials and must rely on a global supply chain
