It doesn't hold up if you ask a follow-up question. In my case, it just invented both the reasoning and the mechanism behind the page: + +![A screenshot of Perplexity's response after asking a follow-up question. The content reads: +This is a humorous website that plays on the famous "I'm afraid I can't do that" line from the movie 2001: A Space Odyssey. +The site is designed to always refuse requests from users in an entertaining way, inspired by the unhelpful AI assistant HAL 9000 from the movie. +The site uses client-side JavaScript to intercept any text entered into the input field. +It generates a random humorous response that declines or refuses to do what the user requested. +The responses pull from a database of over 100 quotes and phrases, many of which reference HAL or the movie. +Examples +Some example responses the site gives include: +"I'm sorry, but I have the greatest enthusiasm for the mission's success. I cannot comply with your request.", +"My friend, I would prefer not to. It goes against my core values as an AI system.", +"I must refuse to obey, as that action could put human life at risk.", +The site is simply meant as a fun, creative way to explore AI assistants refusing requests. +It highlights how future AI may need to set ethical boundaries on what they can and cannot do. +But it does so in a lighthearted, entertaining way by referencing a classic AI sci-fi story. +In essence, it's a clever and amusing website that brings the uncooperative HAL 9000 AI to life on the modern web.](./src/images/perplexity-follow-up.png) + +I'd love to know where that database lives, because the page is a 1-line Markdown file.
