PROMPT: Can you write a script for my podcast: Upgrade the World? I always start my podcast by saying "Hello and welcome to the Upgrade the world podcast. I'm your host Josh and today we're going to talk about" and then I say the topic. My topic will be ChatGPT. I want to define AI, define what ChatGPT is, how it got its name, what a LLM is, how data is stored in an LLM, some interesting facts about ChatGPT, how ChatGPT is different from a search engine like google, specific examples of how it can help humanity, and what concerns people have about ChatGPT and AI in general. At the end of the episode, I want you to reveal that you wrote this script based on my prompt and that I'll make the prompt available in the show notes. I always end my podcast by saying "That's all for this episode. Thanks for listening! Until next time, keep upgrading!"
