The use of AI chatbots like Google Bard raises several ethical concerns that need to be addressed. One major issue is the potential for bias in the data used to train these models, which could result in discriminatory or harmful responses towards certain groups of people. Additionally, there are concerns about privacy and data security when interacting with chatbots that collect personal information during conversations. Another ethical consideration is transparency—users should be aware when they are communicating with an AI system rather than a human to avoid deception or manipulation.
