First, thank you for the excellent lecture, and I'm waiting for the next lecture to be uploaded. I'd like to provide some feedback on a few disappointing aspects. 1. Audio quality (my ears get tired due to subtle machine noise in the background..) 2. It's quite disappointing that you don't actually run the code to demonstrate code explanations and practice content, but only convey it verbally (this is the first time I've encountered lectures with so little code execution), and the somewhat chaotic slide composition is also a bit disappointing. 3. When creating the latter part of the lectures, I hope you'll consider the time efficiency of students. Since it's a rapidly changing period, I hope for lectures that are more compressed and refined rather than precious nagging-like lectures from a senior. Although I've shared many disappointing comments overall, I took the course expecting valuable know-how from a senior developer, and it's definitely a good lecture, so I plan to continue referring to other lectures as well. I look forward to it.
