You're pretty wrong. No organization can just spin up large international companies. I don't know where you'd get such an idea from. Even the technical parts of Uber alone would take years to replicate. The app frontend? Sure, with manpower you can get that out in a few months. The backend, supporting infra, legal systems, customer support, relationships with users, restaurants, etc? Years to decades. Google could never do it, they are too big to move fast. Think, when is the last time Google successfully launched a project of even a fraction of the scale of Uber?
