I'm having a hard time imagining how a Python tool could be a solution to a performance problem at the Google scale.

Are you under the illusion that a high-level language cannot "scale"?

Python is a high-level language, a bytecode language, a standard library, and a variety of interpreters and compilers. And a large community of shared libraries, forums, collaborators, etc.

Java is a high-level language, a bytecode language, a standard library, and a (smaller) variety of interpreters and compilers. Given their similarities, why would you expect that one language can, but the other cannot create a "scalable" software project?
