Poe's got enduring relevance for our era of unreliable narrations. His 1845 short story 'The System of Dr. Tarr and Prof. Fether' – set in a private mental institution – popularized the adage, "Believe nothing you hear, and only one half that you see."

In our era of generative AI, that needs a small update – "Believe nothing you see or hear, and only half of that over a strongly-authenticated channel from a reliable source". But the story's themes of communities-of-mental-illness and blurred boundaries between doctor and patient (or between therapy and enablement) still resonate.
