This lecture truly opened my eyes to the use of AI. Until now, I had only used AI for simple tasks like searching for information, asking questions, or fixing code errors. This was the first time I learned how it can be applied to work so systematically. Thank you for the great lecture. At first, I thought I could just listen to it casually. Since the keyword "AI marketing" is so common on YouTube, my expectations were a bit low. However, as the lecture progressed, I couldn't help but listen intently. Now, I'm feeling impatient to finish the entire course once and then re-watch it while immediately applying it to my work. If there is anyone like me who uses AI at a very basic level—essentially just replacing old web searches with AI—I highly recommend taking this course.
