The recent mid-air collision between a military helicopter and a commercial plane has highlighted the potential consequences of communication ambiguities in human-AI communication. The use of generative AI and large language models (LLMs) can lead to such ambiguities, which can be disastrous in high-risk life-related situations. The NTSB report on the incident will investigate the ambiguity in communication between the controller and the helicopter pilot, which may have contributed to the crash. It is important for both parties to be aware of potential ambiguities and for AI to be explicitly designed to deal with them. Users of AI must remain vigilant and seek clarification in higher-risk situations to avoid miscommunication.
