Right. Google is going to reduce the code size to a million lines of code. For Search, YouTube, Maps, Docs, GMail, Hangouts and all the infrastructure projects that go with it. (And probably a ton of things I forgot to mention) Compare, to, say, Apache alone: 1.8M lines of code. Or Riak: 250,000 lines of code. Just because it sounds like a lot to you doesn't mean it actually is quite as much as you think.
