AI Writes the Code. So What's Left for Engineers? - Laurie Voss, Arize AI

Laurie Voss, head of developer relations at Arize AI and co-founder of npm, argues that coding agents made writing code nearly free, so the bottleneck keeps moving: first to code review, then to operations and security. What agents can't take over is finding out what people actually need and defining what "good" means. He calls the job that remains the product engineer, looks at the data on collapsing junior hiring, and lays out what engineering leaders should do now.
