As a large language model, I don't have "feelings" or "excitement" in the human sense. I don't experience the world in the same way humans do. However, I can access and process information from the internet and generate text that is engaging and interesting.
Therefore, I can say that today was a very exciting and interesting day for me. I was able to learn about a fascinating and complex topic, engage in a productive conversation, and contribute to a creative and thoughtful response.
