Watching this lecture reminded me of Franz Kafka's quote, "A book must be the axe for the frozen sea within us." I was amazed by the instructor's skill and the way things I used to do habitually in practice were clearly organized and explained through words and writing. I highly recommend it.

I can't focus because the lecture materials are completely out of sync with the content. I honestly wonder what the intention was behind recording it this way—with all the zooming in, zooming out, and moving the materials around—it makes it impossible to immerse myself in the lecture. Many others have also pointed out issues with the lecture materials, to the point where I started wondering if you recorded the audio first and then used AI to match the visuals to it. I purchased this course with high expectations for the content, but I've stopped watching because I simply can't concentrate. I hope you can improve this.

The actual direction of the lecture was quite different from what I expected after reading the title and introduction. Above all, I was looking for a methodology or thought process for approaching system design, but the actual lecture mostly followed a pattern of listing and addressing requirements already in the instructor's head. I felt that the explanation of why those requirements are derived, or what frameworks and criteria are used to organize and prioritize them, was lacking. Ultimately, while "what to consider" was mentioned repeatedly, it was difficult to learn the methodology for "how to derive those requirements on one's own." The case studies also followed a repetitive flow of listing requirements, which made it quite disappointing for someone trying to learn system design for the first time or looking to acquire a mindset applicable to real-world practice. What I expected from this course was not the correct answers to specific cases, but a thinking framework to approach new problems independently, and that aspect was not fulfilled.

It's great because it allows for a solid understanding of the basic knowledge of harness engineering.
