I got to see this demo'd at a conference in Sydney recently, and it's really cool.
It's not super serious, but it's not meant to be -- it's not pitching to be your enterprise AI strategy. However, even though it's presented in a playful way, I suspect it's quite powerful, and expect The Internets will build some cool stuff atop it.
It's a fun and creative way to explore playing with LLM's, and it's brilliantly executed! Happy to see it here on HN.
