> 200K hours? This can't be right. If the engineers are paid $50/hour, that is a cost of $10 million just to create a digital replica of the process?

I don't think that's so farfetched - It was rumoured that Tesla bought a Nissan Leaf to take apart and see why it was cheap, and there are companies that buy products including cars, to tear apart and write reports on materials, components, production techniques, and costs for other companies (couldn't find the example I remember)
