Granted this is not super common in these tools, but it is essentially unheard of in junior devs.
This doesn't match my experience. Consider high profile things like the VW emissions scandal, where the control system was intentionally programmed to only engage during the emissions test. Dictators. People are prone to lie when it's in their self interest, especially for self preservation. We have entire structures of government, courts, that try to resolve fact in the face of lying.
If we consider true-but-misleading, then politics, marketing, etc. come sharply into view.
I think the challenge is that we don't know when an LLM will generate untrue output, but we expect people to lie in certain circumstances. LLMs don't have clear self-interests, or self awareness to lie with intent. It's just useful noise.
I wonder if it's unheard of in junior devs because they're all saints, or because they're not talented enough to get away with it?
