## What Jamie wrote

Agents aren't just helping us write software, and they aren't just end user features, they are actually helping evaluate and build the software too. Without too much effort you can create agentic loops that evaluate how your product is performing and automatically works to improve the experiences that get negative scores. This is almost a standard operating practice now in part because there is so much data you can’t possibly do it any other way.
