Funny enough, you wouldn't be able to work fast at all in a 10 MLOC codebase. Working with and navigating that amount of code is a bummer. Imagine for a minute

Funny enough, you wouldn't be able to work fast at all in a 10 MLOC codebase. Working with and navigating that amount of code is a bummer. Imagine for a minute, if there were 50 developers (ignoring managers and administrative overhead) trying to understand 500 lines a day (a medium sized module in most languages), they still wouldn't be able to go through half the codebase in a whole year. So basically most of codebase can't be read or maintained.
