Writing your own library also has the disadvantage that 100% of the new hires have never seen how to use that library.

  As opposed to "a library that talks a specific protocol to a medical devices" or "a library that writes some obscure data format used by some government somewhere on earth" which new hires wouldn't know how to use either because only a hundred people on Earth have ever used either of those?

    Actually yes. While there are a lot of different medical devices if you have an engineer who worked with that specific device before (not unlikely if you hire for that) will most likely have worked with the vendor library, but not with yours.

      In that case, should you choose to write your application in Lisp for whatever reason, it's very likely that you'd be able to use that library from Lisp with a more-or-less isomorphic API and recycle that knowledge.
