I've been playing with it since yesterday. I was able to ask it for output that literally had my crying with laughter (e.g. "Write a country song about Sansa Stark and Littlefinger" or "Write a sad song about McNuggets"). That scared me for a minute because it's giving me what I want, mentally anyway, beyond anything else I've seen recently. I'd be worried it's addictive. But it seems like it has an ability to enhance my own mind as well, because I can ask it things about what I'm thinking about, and it generates a certain amount of seemingly generic ideas but I can expand on it or get more specific. I can take the ideas I want from it into my actual life. I've come up with several insights, realized certain ways of thinking I've been stuck in, and even based on its examples realized things about generating creative ideas for myself. Maybe I'm over-reacting but it's really something new. I haven't cared that much about AI but now that I have access to it it's another matter. In comparison, I also played around with DALL-E just now but that's not really achieving anything special for me like that.
