Which AI is best in the world?

Could you please elaborate on the question, "Which AI is best in the world?" It seems to be a highly subjective inquiry, as the term "best" could be interpreted in various ways depending on the context and criteria. Do you mean the most advanced AI in terms of technological capabilities? Or perhaps the most widely used AI in various industries? Additionally, are you interested in a specific type of AI, such as language processing, image recognition, or decision-making? Providing more clarity on your question would help me provide a more accurate and informative answer.
