Google employees have begun to question the effectiveness and functionality of the AI chatbot Bard, raising doubts about whether the company should invest significant resources in its development. Additionally, the application of AI technology has sparked discussions on ethics and social responsibility, including whether AI should be used as a lethal weapon. Google has responded that these discussions are part of normal operations and they hope to hear user feedback to improve the user experience. However, Google's competitive position in the AI field is under threat, and some employees are suggesting limiting the use of Bard.
