Generated code doesn't have to be magical. The generated code should off course be reviewed by a person from time to time. It must be debuggable and readable/understandable too. Otherwise it doesn't make any sense.

A good example for generated code are typed clients for an OpenAPI interface. Instead of writing a REST client on your own based on a spec, you generate it. And if something isn't right in the first place, don't edit the generated code, fix/configure the generator instead!

Or database models. Either generate the database from the models or the models from the database.
