C - Neutral: The boundary between AI's toolhood and the user's behavior
1) Conclusion: AI has no feelings, but the human cost of communication is real
AI only computes tokens and feels no emotional damage or humiliation, so no ethical violation is committed against the AI itself. In the interaction between an agent and a human, however, swearing lowers problem-solving efficiency, causes systemic pollution (cache invalidation, misfiring guardrails), and over the long run distorts the human user's interaction norms. So the point is not a legal or ethical ban, but avoiding swearing from the standpoint of "efficient engineering and communication guidelines."
2) The illusion of performance and clarity
Some claim that harsh, swear-laden feedback jolts the model awake, but from the standpoint of an LLM's attention mechanism, swear tokens are nothing but noise. In a debugging situation, handing over a concrete error trace, stack frame, and expected output is overwhelmingly better in both token efficiency and accuracy than "you idiot, rewrite it." Swearing may signal the intensity of feedback, but it cannot add information.
3) An alternative from the agent-interface standpoint
An AI system should not hurt usability by over-blocking a user's momentary emotional outburst (frustration, a sigh), but for repeated and destructive swearing it should keep a meta-feedback guardrail that asks back about the task state and error cause instead of emotionally responding in kind. In other words, guarantee flexibility as a tool, but let the default of the interaction converge on clear technical instruction.
