Steve Tarcza, director of Amazon Stores, offers a candid counterpoint to AWS's keynote hype about agentic AI. While the keynote described AI as 'magic' and highlighted Kiro's role in rebuilding an inference engine in 76 days, Tarcza reveals that his team requires human review of every AI-generated output before anything ships. He acknowledges persistent issues like hallucinations and AI going beyond its specifications, noting that spec-driven development reduces but doesn't eliminate these problems. He warns against the trend of laying off junior engineers, arguing that human talent must be maintained to review and sustain AI-assisted systems. His team also avoids using AI for deployments, preferring deterministic automated systems. The contrast between the keynote's enthusiasm and the engineering team's measured, human-in-the-loop reality is stark.
