The transcripts provided don't mention anything about Robert Greene or JRE #464. However, I'd be open to discussing any topic that comes up, whether it's about a specific drug, addiction, or something completely different. I always aim to keep a broad perspective and an open mind. That's the beauty of the Joe Rogan Experience - we explore all areas and angles, and no subject is off-limits. But without further details about Robert Greene's conversation, I can't dive into specifics. Let's just say this - the exploration of consciousness and the human condition is a fascinating journey, and any substance, experience, or idea that contributes to our understanding is worth discussing.
