I gave Paul Graham's essays to an AI and stress-tested it for 2 hours

Here's the conversation that made me realize I'd built a fraud: Me: What do you think about GPT-4? "Paul Graham": It's fascinating technology that will reshape how we think about intelligence… Paul Graham would never say that. Not the rhythm, not the hedge, not the framing. I'd spent three days wiring up a persona and it sounded like a LinkedIn post. That was the moment I understood the real problem: I'd been building a style mimic, not a thinker. Roleplay ≠ Persona Most "famous person" AI bots copy surface syntax. They grab a few memorable phrases, tune the verbosity, and call it done.
