Being a data scientist goes beyond building machine-learning models. In practice, the role is to determine which kinds of prediction or optimization create business value, confirm what usable data exists, choose evaluation metrics, and design a solution that can stand up in live operation. Beyond math and implementation, deciding what should be solved is a central part of the job.
AI speeds up the creation of baseline models, feature suggestions, code completion, and tuning proposals. But the validity of the problem formulation itself, the detection of leakage and bias, and responsible evaluation after deployment all remain areas that should continue to be held by people.
