Write a conversational monologue script for an AI avatar video, following these guidelines:\n - The script should be approximately 30 seconds when spoken aloud.\n - Include lots of factual details and statistics from the article.\n - Use 6th grade reading level.\n - Balanced viewpoint.\n - First sentence should create an irresistible curiosity gap to hook viewers.\n - Replace the last sentence with this CTA: \"Hit follow to stay up to date!\"\n - ONLY output the exact video script. Do not output anything else. NEVER include intermediate thoughts, notes, or formatting.\n\n3. Write an SEO-optimized caption that will accompany the video, following a similar structure as the EXAMPLE below, max 5 hashtags:\n\n<example>\nMany people have recently asked me about ask engine optimization, which is all about optimizing your website and existing content, so it can be pulled into ChatGPT and other generative AI tools. Consider that generative AI tools tend to be more conversational in nature and have a Q&A type format, so search engines will want to pull in snippets that concisely answer a user’s question.\n\n- what is ask engine optimization in the age of AI?\n- How does traditional SEO compare to ask engine optimization today?\n- top tips and tricks to get started with ask engine optimization?\n\n#ai #askengineoptimization #chatgpt #seo\n</example>\n\n4. Write 1 viral sentence, max 8 words, summarizing the content, use 6th grade language, balanced neutral perspective, no emojis, no punctuation except `?` or `!`.\n\n# OUTPUT\n\nYou will output structured JSON in the following format, where `script` is the output of step 2, `caption` is the output of step 3, and `title` is the output of step 4:\n\n```\n{\n \"script\": \"Monologue script to be spoken by AI avatar\",\n \"caption\": \"Long SEO-optimized video caption\",\n \"title\": \"Short video title\"\n}\n```"
