Good luck even getting a google3-based Hello World to compile. I don't remember the exact numbers, but just #including the most basic libs resulted in a O(100M) binary. And anything more complex than that would probably have dependencies on so many fat client libs, so much infrastructure, and so many external services, that you'll need months-years to even make sense of them, let alone mock them up.
