If you read between the lines, what Chang is really saying is TSMC cannot find enough qualified American talent to do the jobs TSMC needs to operate. So it must spend extra money (more cost) to send every new hire in America to Taiwan to get trained. Furthermore, due to this talent shortage, additional engineers from Taiwan must be hired, trained, and deployed to America to make TSMC Arizona function (with doubled salaries and extra benefits to boot). These trainings are not some two-to-four week corporate offsites, but up to one and a half years long!I don’t think I’ve heard of this kind of commitment to training from a company before. I hope it works out, but something about Arizona makes me feel like this will end in an ugly way, but I can’t really back up that feeling.
