I'll admit that I haven't followed the chatter about TSMC Arizona at all. But how does what you say square with https://semiwiki.com/forum/threads/tsmc-overseas-fabs-see-pr...?
People really don't understand how this stuff is borderline magic turning silicon into these things. There's so much that can go wrong at every step, it's the most advanced manufacturing process on Earth.
Once upon a time chips went down in value but I don't think that's happening anymore, lot of other people seem aware of that. Not to mention the semiconductor talent is getting eaten up like pancakes everywhere.
