§01AI productivity begins with developer experience
Nicole Forsgren frames the conversation as a question of developer experience rather than code output.

She describes DevEx as the everyday friction, workflows and support involved in building software, and argues that a team can increase output in ways that create toil, cognitive overload and eventual burnout. Flow, cognitive load and feedback loops therefore reinforce one another: AI-driven agent workflows can interrupt flow when developers repeatedly prompt and review, yet carefully designed tool chains can move flow to higher-level planning, delegation and system evaluation.
