From a manufacturing perspective, the equipment was there because they've been working on it 20Y; whether the vaccine worked is a separate question. By analogy, it's one thing to have a fab, a working fab can make 5nm chips as designed at some yield, however, the fab is not responsible for whether the chip designs work or are valid. My point here really was that tech people, and especially people in the software industry, ignore that the bulk of the work isn't the equipment, it's the long tale of supply chain, manufacturing process and QA. All of the 5nm equipment exists today, it's the other parts that are the hold up. Essentially, in our own domain we know better, and we should really understand this and stop making this mistake in other domains.
