While AI is most effective at automating narrow, repetitive tasks, it’s less capable of stitching those tasks together into a coherent whole. A full-stack professional knows how to orchestrate —they use AI to handle discrete components, while maintaining oversight and strategic control across the entire workflow.
You need depth, not least because it's essential for AI oversight. Only someone with domain fluency can evaluate a model’s outputs, catch subtle errors, and know when to override. And you need breadth because while AI excels at narrow, repetitive tasks, your edge becomes being able to understand adjacent domains.
