I learned a new term this week: Turing pattern.

I learned a new term this week: Turing pattern. In 1952, Alan Turing showed how two chemicals (one that amplifies itself, one that suppresses it but spreads faster) can turn a blank, uniform field into spots, stripes and mazes. No blueprint, just local rules. @turinginst So I tasked @claudeai Opus 5.5 with making a 90s explainer connecting it to LLMs. Every pattern you see is a live reaction-diffusion simulation it wrote and ran. Script, voiceover, music and SFX too. We can see correlations with how @AnthropicAI controls the bulk of the model parameters via the boundary of Constitutionsl AI and constitutional classifiers, downstream of the AdS/CFT academic priors of cofounders Jared Kaplan and Sam McLandish @the_IAS The lesson: don't design the pattern. Design the rules. 🧵👇
