Some quick thoughts since the help of AI can really make an impact on artists. Don't let AI create an entire ARG. Don't let AI create all the visual elements. Some basics. Let AI help play a tour guide, a mild answering of questions. But leave the AI at that sort of NPC mode.
Directed Primarily Towards: OpenAI, Grok, and Copilot, but applies to others. Any ARG AI helps should have zero risk, just fun.
