Thank you so much for such a great lecture. I realize I hadn't considered these aspects and had only focused on simple development, which makes me feel embarrassed, but I think I learned a lot from this lecture. I've watched so many of your lectures. From your early lectures to the two recently opened ones, I'm taking all of them, and your teaching skills keep improving. Since you're fundamentally skilled, you're becoming someone so beneficial that I want to keep you to myself. Still, I hope many people will watch this lecture and learn as much as I did. Thank you for such a wonderful lecture.
