Software scales up in the size of the iceberg of your deployment, and out in the number of teams working on it. Buck (and bazel and pants) solve for scaling both directions at once. Whether you should care about the details and knobs of your build system is strictly a function of the first kind of scaling. Every team building software of appreciable size should think a bit about their build system, and even small teams might benefit from Buck or friends if their iceberg is big enough.
