Very interesting how no-one has commented on Elon stating via. Tweet response that Oppenheimer's view is "obviously wrong".
So far Elon's Tweet has only been liked 60 times?
1) If Tesla's only problem is needing cash, Tesla doesn't have any problems.
2) Tesla still hasn't revealed who the other strategic partners are.
3) There are plenty of private companies and states/countries that are sitting on $1 trillion, looking for a good way to invest it. Investing in a company poised to grow by 5,000-10,000% over the next ten years seems like no brained decision.
3) When Apple began making the iPhone, Apple didn't have the cash, resources, partners, or work force needed to build 10 million iPhones. Apple's strategic partners gave Apple the facilities, resources, and work force it needed to go from 0 - 10million very quickly, because Apple had a great product, that it's partners knew would be a huge but that would benefit their companies, and drive massive economic growth, for the indefinite future.
The situation is almost identical for Tesla.
