From the study:

> We study the impacts of AI coding assistants and agents on software engineering work... across 718 firms.

> Our primary source of data is Jellyfish (“JF”), an analytics platform used by firms to understand the activity of their software engineering teams.

What about all the software being built by everyone else not using Jellyfish? What about the small companies that don't have the same operational bottlenecks and truly are building more than their larger competitors? What about the solo founders starting companies and building software which they never would have built without AI?
