It took two and half months to go from 20% to 80% of code being written by AI 😮

Using Agentic Claude Code and OpenAI's Codex it took Andrew Easter and his team two and half months to go from 20% to 80% of code being written by AI.

As Andrew says, "This is unprecedented levels of change", made available due to Claude Opus 4.6 and Codex 5.3.

It's not just about being more productive. Andrew urges us to ask, "What is the human cost of all of this change?"

Listening in Andrew describes the change in a developer's primary job. It's no longer about writing code, it's to facilitate the coding process. It seems the role has opened up. Developers are now prompt engineers to explain what they want to build and code reviewers to review the generated code. Managing the context switch is now more important than ever. It's all about setting up successful workflows. Train agents to follow good practices around architecture, coding patterns and testing patterns.

I was fortunate to work with Andrew in various contexts and I'm so glad he's spoken on an Into The MoTaverse podcast episode. He's a top bloke with much experience and many insights. This is a must‑watch/listen if you really want to understand what developers have been going through, and continue to go through, in their relationship with AI.

Plus thoughts on what these rapid changes mean for humanity.

It's also just cool to listen to two CEO/CTO level people chatting about what matters. 😎
