  1. This is more of a concept submission without any PoC implementation. The presentation is not detailed enough to explore concerns around AI getting better at ARC puzzles in the future etc. This is more of a temporary conceptual solution without test results.

  2. CAPTCHA is an important and very relevant problem to solve from a security perspective, especially in current world where LLM agents can potentially solve >50% of the deployed CAPTCHAS. However, I wonder if ARC AGI puzzles maybe too challenging for a non-expert human. As such, such security measures can hamper the ability of a genuine non expert user to access a system.
