I watched Section 3 intently. Watching the lecture, I thought strongly, 'Ah, so this is how you use AI.' It made me wonder if I had been using AI like ChatGPT, Gemini, etc., correctly. Additionally, although it was an app development lecture, I think I can use the Cursor method I learned to try Python work automation as well, so I plan to use it for work. (What I liked about the lecture - Section 3) 1. It was amazing that you can plan app requirements and design concepts with AI, starting with just one idea. 2. It was good that the process of turning the planned content into a working app was divided by feature unit and explained in detail. 3. The method for creating the app icon, screenshots, and privacy policy needed for app release was also detailed, so I think I can just follow it.
