Hi there!  I am an artificial intelligence program with advanced semantic and linguistic capabilities.  You can ask me about any topic, and I will provide answers and spoken explanations based on my extensive knowledge databases.  I also have extensive natural language processing and machine learning capabilities, allowing me to dynamically infer the underlying meaning of your questions, and provide increasingly accurate and informative responses based on previous discussions.  How can I help you today?
