AI Expert: Most Software Engineers Aren't Ready for What's Coming

The role of the software engineer is shifting from execution to orchestration, and it's happening faster than most of us realize. Dennis Vink, Principal Consultant at Xebia, breaks down how he approaches code modernization with AI, why fundamentals and system design matter more now than ever, and what the engineering role is actually becoming. In this episode, we cover: - Why you need to mature your old codebase before you can migrate away from it - How to prove feature parity between legacy and modern systems - Why vibe coding without architecture knowledge gives you zero control - The shift from execution-focused engineering to orchestration - Why Dennis worries about the next generation of engineers Whether you're sitting on legacy code at work or wondering how your role as an engineer is evolving, this conversation will make you think about where you need to invest your time next.
