By that article, Uber took in $17+ billion dollars, showed losses of $10+ billion, and created a company worth an estimated $70+ billion. Even give them a 75% haircut from there and they still broke even once you cash cow the company, harvest the tax losses in future years, and eventually wind it down. I'm not buying in at $72B, but it's not clear at all that they've destroyed investor value nor certain that they will in the future.
