I find this to be a poor analogy.

    humans do work
    they speak to other humans to coordinate
    speaking a different language lowers coordination bandwidth

    humans write programs
    they write programs in any language to produce any artifact

I dont see how the method of artifact production relates to coordination bandwidth

the purpose of programming languages isn't to facilitate communication with other humans, a source code artifact is isomorphic to a binary artifact, its purpose is to encode a description, like DNA.
