This is cool, but at their scale I wonder if they wouldn't be better off rewriting most of their codebase, or at least a performance-critical subset, in something like Rust or Go. It may seem like a lot of work, but making Python faster isn't exactly trivial either. Also, I love Python, but using it for huge projects like this sounds dubious at best. I think the benefits of static typing really show when projects grow large.
