Demos run with R, scikit‑learn and Microsoft Cognitive Services expose concrete failures: R linear regression: one outlier raises R² from ~2.5% to 98% and makes p≈0, decision trees carve fine grids on a simple diagonal dataset and become unreadable, APIs label surreal composites as dogs or miss an elephant in an office, and medical nets learn shortcuts — pneumonia model looks at a shoulder tag and skin lesion classifier flips to malignant 100% when surgical marks or scale change. The problem is biased, messy training data, not mysterious models.
