Chips!
The CHIPS act passed in 2022 allocating $52 Billion dollars for indigenous semi-conductor development in the US. Not a single chip produced yet. Lack of talent, infrastructure, and frankly a relatively lazy workforce is to blame. Taiwan sent its best and brightest but they have difficulty hiring talent, there is no readymade supply infrastructure, and while a Taiwan Semiconductor Manufacturing Corporation (TSMC) employee is motivated to come to the Taiwan factory in the middle of the night on a weekend to fix production issues, no such luck in comfy old Arizona it seems.
