The lecture itself is good in that it provides an overall explanation of what Spring Boot is. However, for someone with zero knowledge of Spring Boot, it seemed like it would be difficult to even draw a blueprint. When I only took this lecture, I even thought that I was not qualified to learn Spring. Instead, after taking more than half of the Spring Core Principles class, I understand the overall things that were mentioned here. In fact, at the very beginning of the lecture, you said to just skip over it like 'Oh, I see'. I think it would be right to just skip over it. Then, if you wonder what I am doing here, then it would be good to take the Spring Core Principles class.
