He has access to all sensitive info, he's the chief officer! He would not have access to some sensitive unreleased, but the rest he's pretty aware. And he signs every deal.
A single clue really? I reckon he knows a decent amount about chip manufacturing. You know, as part of his role getting microchips designed and manufactured for thirty years. Ok he might not know the minutiae about the techniques used at TSMC but he’ll know a huge amount - he’s not just hand waving at subordinates getting them to deal with it. The fact that he doesn’t yak on about it shouldn’t be confused for ignorance.
I don't know him at all, I just have a basic understanding of Wafer fabrication and Integrated circuit design. Which is more than can be said of the US government. This whole thing is nonsense.
