I'm responding to this question: > what if the model of both businesses just isn't actually viable without massive injections of funds? I don't know if Uber's valuation or investors are correct. The question is whether or not the business (or one like it) can fundamentally exist without investors pouring money into it. By your claim, it sounds like you'd agree with me because a competitor is likely to emerge with similar or cheaper rates. I agree. But that in no way supports parent's claim that the price (or business model) may be unsustainable.
