Only 25 million? :) Google had billions a decade ago...

iirc they also vendor(ed) many of their dependencies, several layers deep, which still counts for "stores" though it's rather different than "wrote" / "maintains".

Very true. It was still hundreds of millions of lines of first party code a decade ago, and could easily be over a billion at this point.

Yeah, I can definitely believe that Google would break over a billion handwritten. It's a big company that has been around for a long time.

It's still absurd. But believable.
