Right? I mean, special snowflake libraries that everyone can use do exist, don't get me wrong, but they're usually created by people whose sole job it was to create exactly that, a reusable API for <insert domain here>. There's very rarely an opportunity to repurpose old code in a new project if the goal of "API-izing" it wasn't in mind when it was written, and many times when people try it's a disaster. If code could be re-used efficiently, we wouldn't need half as many programmers as we actually legitimately do.
