🤔 Brief reflection

Recently, I have been feeling the limits of vibe coding a lot. The code complexity is becoming too high.

Is my skill lacking? Or is AI performance lacking?

It is probably both.

For using Cursor AI, the cost is too much of a problem.

For using GitHub Copilot in VS Code, the performance is too much of a problem.

Still, I am using Pro through the GitHub Education plan, and I can use the Claude 4 Sonnet model as much as I want, so that is nice…

If I were financially free, I probably would have used Claude 4 Opus like crazy in Cursor AI.

To feel the rich-get-richer and poor-get-poorer gap here lol. Damnㅠ

Anyway, once this Gurumiya project is completed to some extent within 1-2 weeks, from the next project onward, I should lower my AI dependency a little by doing recommended-code coding(?) rather than vibe coding.

It may be a premature judgment from my lack of experience, but for now, coding that depends entirely on an AI Agent feels like poison to me.

Even though the Flutter course is now slowly heading toward the end, I still cannot understand how the generated code works.

If this continues, scalability and stability will become a real mess later.

Below is the scene where Firebase is set up in an instant in a project that was managing state with Riverpod.

Even properly learning Riverpod is hard enough, but seeing a more difficult Firebase project get set up in an instant…

Anyway, my head gets complicated.
