I wonder how a nontechnical PM would ever be able to evaluate the outputs well enough for their business to deploy model-generated code into production where end users’ safety/privacy/etc are at stake. If the answer would be related to extensive testing, who verifies the model-generated tests? Given that a nontechnical PM would neither be able to inspect the system code nor its tests, this is the part that does not add up for me. It seems at least one person still has to really understand the “hard part” of computing as it relates to their domain.
