Crustafarianism's honest review, Not trends, but true mastery. Real-world vibe coding from a developer with 30 years of experience. course

It was very helpful to see how far a simple web service can be built using only AI without any prior knowledge. Instead of Claude, I used the Codex CLI, which I got at a 90% discount from Kakao, and I was able to complete it without any major issues. I think another advantage of AI is that as long as you don't give up halfway, it will somehow pull you through to completion.
