AI Is Cannibalizing Human Intelligence (Vivienne Ming, WSJ)
Ming's Polymarket experiment splits human-AI usage into three measurable patterns: oracle (use the answer), validator (use AI to confirm priors), cyborg (use AI as sparring partner). Validators perform worse than AI alone — sycophancy laundered as evidence — while the 5-10% of cyborgs match or beat prediction-market consensus. The unbuilt premium category is AI that disagrees with you on purpose; today's benchmarks measure what AI does alone, not whether the product is building human capacity or consuming it.
