코드를 직접 타이핑하라

In the era of AI-driven development, the ability to 'freecode'—writing precise syntax and types from memory—remains a critical foundation for high-level architectural thinking. Actively generating code rather than passively consuming it leverages the generation effect to build robust mental models, preventing technical debt like redundant implementations. Mastering these low-level details is not a regressive exercise but a prerequisite for effectively guiding and verifying AI agents in complex software engineering tasks.
