    Root Causes 656: The Trouble with Recursive AI Training

    21/08/2026 | 6 mins.
    Since frontier-model AIs have been trained on a large portion of published human knowledge, widespread publication of incorrect information can taint AI results. As more AI-generated slop finds its way onto the internet, this runs the risk of further poisoning AI results. This ultimately can result in completely unusable information.
