CircleCI study: code throughput up, delivery down, reliability slipping

Seems like code production is up but mainly in feature branches. Main branch changes are down. MTTR deteriorating. This is for all but the highest performing (top 5%ile) teams.

This has to be driven by AI adoption. I'm trying to keep an open mind, but I can see how this is productive. Maybe the optimistic take is the top 5% are showing the way and the remainder will follow? That seems a bit too optimistic though, because the bottom 95% are probably burdened by technical/organizational debt that limits their ability to adapt quickly enough.
