Why The Best Software Engineers Are Solving Code Review Bottlenecks Now

AI generates 10x more code, but your senior engineers still review it by hand and it's burning them out. Even Google admits code review is now the bottleneck nobody knows how to solve.

Florian Buetow, AI engineer at Xebia, has been running experiments to eliminate the human from the review loop entirely, and what he found changes where engineers should focus their effort.

In this episode, we cover:

• Why "stop doing code reviews" is a serious answer (and what replaces them)
• The guardrails that gave the most value: Semgrep rules, architectural unit tests, and stop hooks
• Why your harness matters more than the model
• How Amazon and Google police AI-generated code with policies
• AI burnout, cognitive debt, and "cognitive surrender": what stays your responsibility
• Step one for adopting agentic software engineering in your team this week

Whether you're an individual developer drowning in AI-generated PRs or driving AI adoption across a large engineering org, you'll leave with concrete experiments to run.
