1. The Arts and Crafts of Work in the AI Era Toward Mastery in Software Development Yoshihito Kuranuki / Sonic Garden Inc. Laravel Live Japan 2026 — Day 1, 14:30 The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 1
2. About Me Yoshihito Kuranuki CEO CTO Working in both Rails (Sonic Garden) and Laravel (Kurashicom). A programmer at heart, an executive in role. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 2
3. Today's Theme Rails and Laravel share a common philosophy: Developer Happiness. This year, at Laravel Live Denmark 2026, DHH will join Taylor Otwell for a Fireside Chat. Recently, DHH arrived at a particular phrase. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 3
4. The Arts and Crafts of Work — DHH Rethinking work as a craft — Yoshihito Kuranuki We arrived at the same words, independently. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 4
5. "Hand-typed Coding" In Japan, we say "te-uchi soba" — soba noodles made by human hands. Only when machine-made noodles became the norm did we need a word for the hand-made kind. The same is happening with code. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 5
6. What Will Become of Programmers? AI writes the code. AI reviews the design. AI writes the tests. What is left for us to do? What happens to our careers? For us → Work That Feels Like Play The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 6
7. What Is "Work That Feels Like Play"? The person is working seriously, wholeheartedly Yet it looks as if they are immersed in play To make this possible, we have valued: Intrinsic motivation Flow → Business outcomes The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 7
8. How Sonic Garden Works 15 years, ~60 people, all top-tier programmers We engage with clients as their virtual CTO One programmer: strategy → code → ops Like lawyers, multiple clients per programmer what we call → extreme agile The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 8
9. What Sonic Garden Doesn't Have No sales targets. No managers. No performance reviews. No top-down orders. No office. No set working hours. What we value instead is self-management — each person decides for themselves, all day, every day. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 9
10. Why Self-management? In software development, top-down orders hurt performance The best performance is born from intrinsic motivation Beyond managing oneself — also building peer relationships and delivering value to clients As a result → Flat community The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 10
11. Beyond Self-management Even without instructions, they take initiative. That's because they see their work as creating their own craft. Doing what was once too hard — that's the joy of mastery. This is what Peter Senge calls Personal Mastery. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 11
12. We Train Young Programmers Ten years of building an organization of self-managing people. Five years ago, we began seriously training inexperienced young programmers. In the AI era, fewer companies hire junior programmers This year, we even hired a high school graduate How do we train them? The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 12
13. The Answer Was Apprenticeship We chose a master-apprentice relationship. Apprentices live near their masters across Japan Side by side, residency-style Analog and old-fashioned — yet the best way to pass on aesthetic sense. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 13
14. Rethinking Work as a Craft In one phrase, what we've been doing: "Rethinking work as a craft (Arts and Crafts)." Inspired by William Morris's 19th- century Arts and Crafts movement. Between Engineering and Art — valuing process, not just outcome. William Morris, Strawberry Thief (1883) The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 14
15. What Was Software Development, Really? Software development was never only about writing code. Deciding what to build Designing how to build it Growing what we built With coding offloaded to AI, more moments of joy become possible. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 15
16. Facing It Together with AI What AI takes is not just coding AI becomes useful in every part of software development Looking for a "safe zone left for humans" — we won't find one AI vs. Us ✗ Problem vs. Us + AI ✓ The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 16
17. What Happened When the Cloud Arrived Cloud → Infrastructure as Code → A boon to programmers AI → AI tools everywhere → The same boon, again The same thing is happening with AI. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 17
18. The Work Isn't Gone — Each of Us Can Do More The scope of what one person can do widens Smaller teams can build larger software Those who thrive: programmers who can build better software with AI. At the core of software, source code remains. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 18
19. Aesthetics is truth. — DHH The beauty of design lives in source code. — Yoshihito Kuranuki Aesthetic sense will be required of programmers in the years to come. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 19
20. The Bar Rises for Professionals ↑ Bar rises for pros the bar ← Programming opens up → In the AI era, programming becomes accessible to many Yet the bar for professional programmers rises "Because it pays well, because it's trendy, because of flexible hours" — fewer will choose programming for these reasons The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 20
21. You became a programmer, because you love programming. Tomorrow's society will be one that respects intrinsic motivation. The Arts and Crafts of Work in the AI Era Yoshihito Kuranuki / Sonic Garden Inc. 21
