Anecdotally, no one in SV ever believed in WeWork except Softbank. I couldn't find anyone to take the Bull case on WeWork, whereas at least some people could argue Uber had a real business model that depended on self driving cars.
WeWork, and Theranos before it, are not really the norm in SV. But SV and the tech ecosystem in general has a culture of "money talks," so when Softbank and Kissinger start backing these ridiculous companies, people think "well, good for them?" and move on. Skepticism towards WeWork's model has been the conventional position since Day 1, but no one is going to argue about the validity of Masa Son's dollars.
