Earlier quoted context omitted.
Will they eventually reach a point where they can just run with the capital equipment they already have, and drop the CAPEX spending down?
Their goal is 10k cars/week, so perhaps then. There's also (reported today) $5B planned for the factory in China, expected to be raised largely in-country but with some American/international investment. And, of course, some capex is always necessary to replace depreciating stock and support new models (pickup, new roadster, and truck all planned).
The thing about these new factories is that they will be using already developed technology and product so the risk is much lower for them than for the original model3 factory.
