Special Episode: Does AI help developers?

AI is helping us write code faster.

But I'm not sure it's helping us ship better software.

These two things are not the same. And right now, I think we're confusing them.

The data is starting to show the gap:

  • AI-generated code contains 1.7x more bugs than human-written code
  • Copy-pasted code is up 48%. Refactoring is down 60%.
  • Pull request sizes have grown 154%. Review times up 91%.
  • Only 29% of developers trust the quality of AI output

If developers don't trust what they're producing, what does that mean for the engineering leaders managing the downstream impact?

The problem isn't the AI. We optimized for output. We forgot to optimize for outcomes.

The teams that get this right won't necessarily be the fastest. They'll be the ones who still treat AI-generated code as a starting point (not a finished product) and keep senior engineers in the loop as reviewers, not just approvers.

Measuring PR volume and lines of code tells you how fast the machine is running.

It doesn't tell you where it's going.

For engineering leaders: are your review processes built for this volume? Or have your senior engineers quietly become the quality layer nobody planned for?
