Agile was built for a slower machine

I've seen a growing conversation on LinkedIn and Reddit about what AI tooling is doing to software teams - Cursor, Claude, Copilot, the whole wave. Velocity is up, backlogs are shrinking - by every measure teams track, things look great. But what's catching my attention is the feeling that teams are losing context - code review burdens have exploded as weeks are compressed into days and features are shipping, but its becoming harder to tell which ones moved the needle. Teams are building faster than ever but its not claer if they're learning faster too.

And it got me thinking: sprints, backlogs, velocity, story points - all of it was designed to manage build capacity. To prioritize carefully, because building was expensive and slow. That was the bottleneck, and agile was a really good answer to it. But what if that's not the bottleneck anymore? For a growing chunk of the work, AI has made building fast and cheap. But the process hasn't changed. Teams are using AI to sprint faster through a system designed for when sprinting was hard.

If building isn't the constraint anymore, what is?
