Great insight, you have found the great fly in the VC ointment. VCs used to fund 10 losers for every winner, and still make money hand over fist. But then with the help of Wall Street and the City of London, they could milk the losers as well and find greater fools to take them off their hands. This is where SV model of "fake till you make it" became a drag on the real economy. The corpses of losers and fake unicorns can be kept on display for decades, piling up and sucking in devoted followers. Meanwhile, the ubermensch of the Ubers are long gone. By the way, I think you meant to say "door on Sand Hill Road".
