Yes. I would think that too. But the market isn't efficient, VCS are definitely not efficient, and it takes a lot of capital to spin up a factory, and the number of qualified people to run this factory is probably in the hundreds worldwide. Also ppl who worked on it in the past might be burned out, or not have access to key IP... Hundreds of things could get in the way
