Don Poorman is the founder of Panta Rhei Publishing—an independent imprint that treats human-AI collaboration not as a theoretical debate but as an active experiment worth documenting. Rather than arguing about whether artificial intelligence belongs in creative work, he decided to test the premise directly by spending six weeks in intensive collaboration with Anthropic's Claude, then writing a 300-page gonzo journalism memoir about the experience. Don has positioned Panta Rhei as evidence rather than argument, demonstrating that human-AI collaboration can produce genuine creative work instead of disposable content and slop.

Panta Rhei Publishing operates as a traditional publishing operation and an active Substack community around three core themes: archival material from years of incomplete projects, meta-documentation of the publishing process itself, and pointed cultural commentary. The entire venture operates on a simple premise—the most interesting way to explore new creative tools isn't to theorize about their potential but to actually use them, then document what happens with unflinching honesty about both the breakthroughs and the mess.
