Agentic AI shifts software’s key advantage from coding skill to domain expertise and validation judgment

The article argues that software’s hardest task has always been understanding the domain, not writing the code. With agentic AI now able to generate software, the critical constraint becomes knowing whether outputs are correct, making domain expertise more valuable than general coding ability in many contexts.

This points to a shift in software development where domain specialists can become effective builders by using AI agents, while engineers without deep context may struggle to validate results. The durable moat may move toward ground truth judgment, workflows, and institutional knowledge rather than implementation skill alone.

Domain expertise has always been the real moat
