This seems to be the most meaningful lecture among all the topics I've studied so far. Whether it was blog content or lecture videos, I thought I had seen many topics, but now that I'm encountering this kind of subject, it feels like I was just digging around in a well the whole time. The lecture itself has such excellent insights and content that allows for a broader perspective. I hope our development culture will grow even more as many people create and take courses like this. Thank you so much for the great lecture.
