The End of "Good Code"? AI, Throughput, and Reliability with CircleCI CTO Rob Zuber

Is “good code” still the right measure of engineering success in an AI-driven world? In this episode of *Humans of Reliability*, Rob Zuber, CircleCI CTO, joins Sylvain to explore how coding assistants are reshaping developer workflows and changing what teams value.

Rob shares what he’s seeing across CircleCI’s customer base: a clear boost in throughput, new bottlenecks shifting from code creation to code review, and the rise of “vibe coding,” where engineers trust AI-generated code they may not fully understand.

He challenges long-held assumptions about readability and maintainability, arguing that software engineering is on the edge of a paradigm shift. For SREs and developers alike, this conversation is a candid look at how to stay relevant, embrace simplicity, and rethink reliability in the age of AI.
