Brainstorming Is Cheap; Research Judgment Is Not Brainstorming with an LLM is easy. Ask for ten research ideas, wait a few seconds, and receive a confident menu of things that sound just plausible enough to be dangerous. Turn up the temperature and the machine becomes “creative.” Wonderful. We have successfully automated the whiteboard intern. ...
Spreadsheet work has a special kind of comedy. A person asks an AI agent to load a dataset, clean a few columns, train a model, generate predictions, and save a prediction.csv file. The agent writes plausible Python. The model architecture is reasonable. The explanation sounds confident. Then the whole thing fails because the agent forgot to pass the filename into the execution tool. ...
Spreadsheet first. Not the model. Not the agent. Not the impressive diagram with seven tiny boxes labeled “planner,” “executor,” “critic,” “memory,” “tool user,” “reflection,” and, inevitably, “orchestrator.” In most companies, data science automation begins with something less glamorous: a messy spreadsheet, a half-documented database table, a recurring report, a manager asking why last month’s number changed, and one unlucky analyst trying to remember whether “customer_id” means account, user, buyer, household, or whatever the CRM vendor believed in 2019. ...
Dataset. That is where many “AI data scientist” demos quietly stop being impressive. A tidy CSV, a small notebook, a polite prompt, and a model that produces a confident answer: this is enough for a video clip. It is not enough for data science. Real data science is not a single question answered by a single model response. It is a sequence of choices: load this file, inspect these columns, define this metric, split the data this way, train this baseline, handle this error, explain this plot, revise the next step. ...
TL;DR for operators The useful question is not whether AI will “replace data scientists”. That framing is wonderfully dramatic and operationally lazy. Timpone and Yang’s paper, AI, Humans, and Data Science: Optimizing Roles Across Workflows and the Workforce, gives a better mechanism: allocate human and AI work by asking what kind of quality each workflow stage needs.1 Early planning needs creative breadth and problem definition. Execution needs accurate, valid, and ethically defensible data and modelling. Activation needs contextual interpretation, stakeholder judgement, and responsible action. ...
