@GaryMarcus @stark4833 Just so you know Gary, that guy has 4o psychosis. I think OpenAI’s handling of 4o was atrocious. It destroyed the brains of thousands of people and they did not do enough to prevent it. David is a victim of OpenAI. If you’re looking for a good anti-AI narrative, there you go.
