Can we finally see inside AI? | The blog post that set the AI world on fire

====================================================== In October 2026, the AI researcher Nick Cammarata of Goodfire published a 26,000-word essay called Neural Networks Are Already Clean. Within a day, The Atlantic reported, Silicon Valley was obsessed with it. Readers called it "the most important essay" of the year, and even OpenAI CEO Sam Altman praised it. If Cammarata is right, much of what the field believed about the inside of AI is wrong.
