Kodak has 3 coating machines in R&D and one in production for pilot coatings. These could be used to make small quantities of films if they really wanted to slow down production. But, with little R&D the training of an engineer is pretty much rote and can be passed on. They are making the same things every day, not making something new.

But, if they shut down, it is truly lost and there are few out here in the world interested in learning.
