From Guild Craft to AI Code: Why ‘Close Looking’ Is the Last Developer Skill
This talk argues that in AI-assisted software development, the key skill is no longer writing code but judging its quality. Drawing on medieval guild craftsmanship and close-looking practices from stained glass analysis, it shows how careful observation can rebuild trust as code generation becomes faster and less reliable.

In medieval guilds, craftsmanship wasn’t just about making; it was about inspection, judgment, and trust. Masters didn’t simply produce work, they certified its quality through careful, trained observation. Fast forward through the Industrial Revolution, when we traded craft for scale. The Aesthetic Movement, or Arts and Crafts movement, reacted against this, and software engineering as a discipline has experienced this tension as much as any 19th century furniture designer or wallpaper artistan.
With the rise of AI tools, developers can generate more code than ever before. But as output explodes, trust erodes. Code that looks correct isn’t always correct. Systems that seem sound can quietly fail. The bottleneck is no longer writing, it’s knowing what to trust.
I’ve been exploring this concept of trust and observation by building a close-looking application for the stained glass of Chartres Cathedral, a place where meaning only emerges through sustained, careful attention to detail, pattern, and context. This work reveals something critical: seeing well is a skill, and it can be designed for, practiced, and improved.
This talk connects these worlds.
It argues that we are entering a new phase of software development where the most valuable skill isn’t producing code, but judging it well. Drawing on lessons from medieval guilds and the practice of close looking, we’ll explore how developers can rebuild trust in an AI-assisted world.
