At first, I was a bit worried because Claude Code felt difficult and had a high barrier to entry, but after taking the lecture, I understood why everyone says it's so important. As a senior engineer myself, I am receiving a lot of help because there are many parts that can be applied directly to actual work. What I especially liked was that it didn't just introduce features, but explained step-by-step from the fundamentals why things are used in a certain way. Many AI tool lectures often just skim through features to follow trends, but this lecture didn't feel like that; it explained things in a way that can be utilized for a long time, which was great. You always quickly reflect new tools and trends, yet you maintain a style that doesn't miss the basic principles, so I personally listen with great trust. Also, your previous English lectures helped me a lot when I was preparing for jobs abroad, and I am enjoying this lecture with great satisfaction as well ✨ I would like to recommend this to developers who want to properly utilize AI in their professional work 😊
