Software Engineering Essay
Summary
The article revisits Rich Hickey's software design principles in the context of AI-assisted coding, arguing that AI tools amplify whatever approach you bring. Rushing without understanding the problem leads to complex messes, while deep thinking first turns AI into a powerful implementation tool.
Highlights
- Rich Hickey's distinction between simplicity (untangled design) and ease (familiar, quick solutions) is more relevant than ever with AI coding tools
- AI tools amplify whatever approach you bring—rushing without understanding the problem means AI helps you build the wrong solution
- Vibe coding creates context complexity as conversations grow longer, burying earlier design decisions under revisions and corrections
- Most critical bugs result from misunderstanding the problem rather than implementation errors, making deep thinking essential
- Effective AI-assisted development requires disciplined phases of problem research, planning, and review to avoid complexity

Source Overview
AI coding tools make it easy to rapidly generate software, but this ease often leads to complex, tangled systems if underlying problems are not thoroughly understood.
Rich Hickey’s principles emphasize the distinction between simplicity (clear, untangled design) and ease (quick, familiar solutions), warning that prioritizing ease fosters complexity and unreliable software. Effective use of AI coding agents requires disciplined phases of problem research, planning, and review to avoid context and code complexity.
