Volume amplifies both signal and defect equally. Pipelines multiply bad measurements, high-dimensional features invite leakage and spurious correlation, and scale can't fix sampling bias it just hardens it. Better insights come from data that's fit for purpose, stable over time, and validated before it reaches downstream consumers. The goal isn't the biggest dataset; it's the smallest one that still preserves the true shape of the problem.
