> I think that if you give the same task to three different developers you'll get three different implementations. Yes, but if you want them to be compatible you need to define a protocol and conformance test suite. This is way more work than writing a single implementation. The code is the real spec. Every piece of unintentional non-determinism can be a hazard. That’s why you want the code to be the unit of maintenance, not a prompt.
