Why I Canceled My GitHub Copilot Subscription After Two Years

Mon, 16 Mar 2026 21:59:07 +0800

I used GitHub Copilot for two years before deciding to cancel my subscription about 18 months ago. Looking back, I’ve realized a few things about the reality of AI-driven development.

The Illusion of Efficiency

AI is everywhere in software now. When it first arrived, the general consensus was: “Adopt AI or be replaced.”

At the time, I wasn’t particularly worried about being replaced. I was three years into my career as a backend engineer with a Master’s degree, and I’ve always preferred understanding systems from the ground up—an obsession that started back in junior high. I enjoy the process of building things myself; to me, coding is more like a craft than just a job.

About Me

Mon, 16 Mar 2026 11:20:00 +0000

Hi, I’m Neil (Yi Min Tsai).

I am a Software Engineer specializing in system architecture and backend development. Rather than simply chasing the latest trends in tooling, I find my passion in exploring the underlying principles of computer science. To me, crafting code is akin to carving a wooden masterpiece—it requires a relentless pursuit of deterministic logic and peak system efficiency.

Engineering Philosophy

In an era of ubiquitous AI, I remain committed to the belief that the engineer must command the “soul” of the system’s logic. Having experienced deep reliance on AI assistants, I made the conscious choice to disconnect from them to maintain absolute mastery over my craft. I believe that true engineering is built upon deterministic truths, not probabilistic suggestions.
