do you not think that if China invaded Taiwan, the top minds there would just leave and go elsewhere? the machines they use are built in the Netherlands. I know it's not quite as simple as that, but I don't think it'd be the end of the world like people are saying. I think worse would be the precedent it would set.
Other companies have the same EUV machines. TSMC also made the good decision in hindsight to make an early bet on those machines.
We know TSMC is dominant - the real knowledge of how they are doing that is in the heads of people working at TSMC. Or maybe better to say that something is missing from the competitors? Process? Management? Everything?
Cadence and Synopsys are US companies that need to know many of the technical parameters of TSMC processes. They might know more.
