What's Their Track Record?

Strong academic record with peer-reviewed publications and prescient critiques of AI limitations dating back to 2001. Founded and sold an AI company, demonstrating practical expertise. Involved in public debates with accurate citations of research, though accused of negativity by AI optimists. No major fact-check failures; self-described as sticking to cognitive science principles despite backlash. Occasional corrections in debates, but overall high historical accuracy in predictions about AI challenges like hallucinations and lack of reasoning.
