Shows concrete failures and fixes: a model claims 90% accuracy at detecting criminals using logistic regression/KNN and a biased CalGang ground truth that even lists infants; benchmarks like Labeled Faces (≈13k) and ImageNet (14M) skew results; LLaion‑5B (five billion) requires “781 years” to audit and overrepresents Pinterest/Shopify images; OpenAI CLIP and Google CLD3 choices bias selection; RAG systems compound errors to ~72% reliability, cause real harms (Air Canada payout), and remain vulnerable to prompt injection and hallucination.
