The time spent listening to this was a waste. Running ChatGPT would be more helpful. Inflearn needs to filter out courses like this. None of the content was specific or practical enough for real-world application, nor was it theoretically solid. It's literally just filled with content that an AI could answer, with images attached. If I'm just going to listen to obvious things via TTS audio, why bother taking the time to listen? Less than 1% of this course content was useful, and if possible, I'd like to request a refund. Even though it's company money, not my own, it still feels like a waste. Course quality is poor. Course difficulty is disappointing! Q&A communication is not smooth. Materials are insufficient! There are issues with the sound.
