On the other hand, AI can enhance security by detecting fraudulent activities or cyber threats. Balancing AI’s benefits and risks to privacy and security is a major ethical concern.
What is the role of AI in surveillance and what ethical issues does it raise?
AI is increasingly used in surveillance for purposes like crime prevention and public safety. However, it raises ethical issues around privacy, consent, and misuse. Unregulated use of AI surveillance can lead to mass surveillance, infringing on individuals’ privacy rights and potentially enabling oppressive practices.

The architecture enables the model to handle long-range dependencies in text, making it effective for many natural language processing tasks.
What are the limitations and ethical considerations of using LLMs like ChatGPT?
While powerful, LLMs have limitations. They generate text based on patterns learned during training but don’t understand the text or the world in the way humans do. They can also produce inappropriate or biased content if not properly controlled. Ethical considerations include the potential misuse of these models for misinformation or harmful content generation. Efforts are ongoing to improve the safety and ethical use of LLMs.
