Scott, I beg to differ. I’ve worked in both aerospace and consumer sectors, and can testify that development in the consumer sector, where it is still done, races forward at orders of magnitude greater pace. 3D carbon fibre and nylon composite printers which were state of the art 4 years ago, are already old hat, being replaced by machines capable of printing metal. Local garages are already starting to print their own parts in servicing, thus reducing dependence on supply chains. The aerospace industry will be revolutionised when manual pilots actually become illegal. Then we will be dialing up 3D printed people carrier uber drones like taxis. And it will all be made possible by enabling folk to generate their own wealth, thus giving them greater spending power to demand all of those things.
