Does AI Coding Actually Help?

The honest answer is: it depends, and the variables that determine "on what" are not the ones most adoption pitches mention. This section starts with the evidence itself — including where a controlled study directly contradicts vendor-reported speedups — then works through what actually predicts whether AI coding assistance helps a given developer on a given task, and ends with how to measure it for your own team instead of trusting someone else's number.
