Gotta say this is absolutely not my experience. I've worked at a lot of companies and have never seen one with anywhere near the developer productivity as Google enjoys. They have the groundwork that enables the velocity, so you can build/test/deploy very very quickly. Other organizations believed they had velocity because they skipped unit tests, code review, production security, supply chain security, etc. Consequently their whole thing becomes a haunted graveyard that everyone is terrified to change.
