> but it seems that the last couple of really huge unicorn companies have all been based on BS(We Work), Fraud(Theranos), and untenable business models (Uber).
What I don't understand, and this is an honest question for this crowd: aren't these viable businesses, in and of themselves? Maybe this is a stupid question. This is probably what allowed them to run so far on what they actually were, but here's the question anyway.
For instance, WeWork seems to be an AWS-for-office-space. Is that not a useful business? If I own a contract for space that can be slotted into anywhere in the world I might want to sit, is that not a useful thing to pay for? One might argue that, if I had the resources to truly care about a world-wide smorgasbord of office spaces to choose from at any given time, I'd have enough resources to lease my own building(s). But it still seems like something the market needs. Did it have to be a one-hundred-billionaire-minting business to rent space into that kind of market?
Theranos seems like a useful thing, and there seems to be an opening in the market for it. Are the cost mechanics of the available technology and the opportunity not aligned? Is there no way to run an economically-viable company providing a blood tester unit with a more-limited set of tests? Did it have to be a unicorn, end-all-be-all, existing-testing-company-destroyer to make any money?
You see where I'm going now. Does Uber need to suck all the money into their pockets to fund their self-driving car efforts (or wherever all this money is going) in order for any of it to work? Surely there's a model of ride sharing through an app that doesn't have to suck, pay their drivers well, and is a sustainable business, right? Does it really have to be the "Uber-of-cars," so to speak, in order to exist at all?
Is the only game left in the Valley, now, unicorns? All others need not apply?
