But: - natural language is flexible, computer languages are less so. - "pretty decent English" still includes hallucinations. I've seen companies whose product demo for generating marketing copy just makes up a plausible review. Hallucinating methods, variables, other packages/modules yields broken code. - the human thought behind natural language is not feasible to directly provide to a model. An IR corresponding to the source of the program is feasible to provide. A trace of the program executing is feasible to provide. Grounding an LLM in the rich exterior world that humans talk about is hard; grounding an LSM in the rich internal representations accessible to an IDE or a debugger is achievable.
