There's also a lot of automation to be done before a factory begins producing something. There are large capital costs, and even larger opportunity costs, to the really slow testing setups for all kinds of industrial goods. For the area I'm most familiar with, batteries, a novel chemical composition for a battery can take 5-10 years, to hit market (leaning towards the latter end of the spectrum). IMO this could be brought down to 6-12 months with much lower capital costs.
