+Well, thank you both for having me. You know, when we talk about creative AI, I think it's important to distinguish between the technical capabilities and the philosophical implications. From a research perspective, we've seen remarkable progress in just the last eighteen months, but there are still fundamental questions about what creativity really means in a computational context.

+Oh wow, this is such a brilliant question. Like, as someone who's been working with AI tools in my art practice for about two years now, I can honestly say it's completely transformed how I think about the creative process. It's not about replacing human creativity — it's about expanding what's possible. And that's genuinely exciting!
