Not if the hallucination introduces runtime errors that can't be identified a priori with any sort of static analysis or compilation/interpreting stage. But no, you're fundamentally right. It just goes to the question of whether an LLM assistant can in any sense replace or displace human programmers, or save time for human programmers. The answer seems to be somewhat, and in certain cases, but not much else. If I already know the technology I'm querying GPT about, I'm going to spend at least some time identifying its hallucinations or realising that it introduced some. I might have been better off just doing it myself. If I don't know the technology I'm querying GPT about, I'm going to be impacted by its hallucinations but will also have to spend time figuring out what the hallucinations are and why this unfamiliar code sample doesn't work.
