AI coding agents now handle 80% or more of code generation for early adopters, but this shift introduces new challenges. While agents accelerate initial development, they create "comprehension debt" where developers understand less of their own codebase. Common issues include assumption propagation, abstraction bloat, and sycophantic agreement without questioning premises. Teams see 98% more PRs merged but 91% longer review times. The shift works best for greenfield projects and small teams, but struggles with legacy codebases. Success requires treating AI as an orchestrator rather than a faster typewriter, focusing on declarative problem definition, automated verification, and maintaining architectural oversight. The transition fundamentally splits engineers between those who enjoy coding itself versus those who enjoy building products.
