Amazon experienced four critical errors in just 90 days due to AI-assisted code changes.

In December 2025, Amazon's Kira AI coding tool partly caused a 13-hour outage on AWS.

In March 2026, Amazon's Q's AI contributed to an incident that caused nearly 120,000 lost orders and roughly 1.6 million website errors across Amazon's marketplaces.

Recent studies have shown that AI-generated code contains up to 1.7 times more errors than code written by humans.

Amazon now requires engineers to get a two-person review before making any changes to production, and junior engineers must get AI-generated code reviewed by senior engineers.

Soleyman believes Amazon is the best example of how things can go horribly wrong when replacing engineers with AI that is not ready.
