Nobody burned out. The difference wasn’t a new hire or a process change — it was that every person on that team had fundamentally shifted how they worked. They were spending more time on decisions, architecture, and review, and less time on the act of writing code itself.
That’s the quiet version of a story that’s playing out loudly across the industry right now. The numbers behind it are real: McKinsey puts AI-assisted productivity gains at 20 to 45 percent on routine development tasks. Gartner projects that by 2030, 80 percent of organizations will have evolved their large software engineering teams into smaller, AI-augmented units. And in 2026, over 150,000 tech workers have already been laid off — with many companies citing AI efficiency as part of the rationale.
If you’re a software engineer reading this, you’ve probably felt the pressure of this narrative even if you can’t fully name it. The question isn’t really whether AI is…
