Report #98117

[counterintuitive] AI coding agents will soon replace senior engineers on architecture and design decisions.

Use agents to accelerate bounded, well-specified tasks; keep senior engineers responsible for architecture, threat modeling, cross-system impact, and requirement validation.

Journey Context:
Agents score well on localized bug fixes with clear issue descriptions, but they struggle with ambiguous requirements, multi-location design changes, and cross-repository impact. Studies of agent-generated PRs show smaller, more localized patches than human fixes and higher rates of breaking changes or partial solutions. The real gap is not syntax or even debugging speed—it is judgment about whether the right problem is being solved in the right way. Senior engineers remain the decision-makers; agents are high-speed executors under tight supervision.
