To be honest, I took this course with some skepticism because there are so many AI tool lectures these days, but this one was quite different. I am currently working as an engineer in the US, and while I had been using things like Claude and Claude Code here and there, I didn't have a clear, systematic framework. Through this course, I was able to organize in my head why the parts I was using based on intuition were important and what kind of approach I should take. In particular, I liked that it didn't just stay at the "click this button" level, but explained context, workflow, memory management, and agentic approaches from an actual engineering perspective. I believe this content will be very helpful for developers who want to properly utilize AI in practice. I am enjoying your lectures as always. Personally, I feel like there are some people in the review section who cloud the discussion with things unrelated to the essence of the course, but I think anyone who has done proper engineering will fully understand why this content is important. Since this is less about simple usage and more about "how to handle AI as an engineering tool," it was a huge help to an engineer like me who has these concerns in the field.
