teropa · x · 2026-08-13
A developer tracked the number of "load-bearing" pull requests made by AI in Intercom's Ruby on Rails monolith.
The data reveals zero AI-written core code from 2011 to 2023. However, occurrences began in 2024 and exploded exponentially in 2025 (jumping from 2 in March to 188 in July). This highlights a rapid industry shift where AI coding assistants are transitioning from experimental tools to writing production-ready, critical business logic.
