Hi Zorba, this is Roy! Thank you for your valuable feedback. The lecture you are currently viewing was produced when ChatGPT was first released (a time when its features were significantly different from the current version). I apologize for not meeting your expectations. From April to May 2025, approximately 30 completely new lectures will be updated sequentially. Currently, 10 lectures have been uploaded, and you will soon be able to see much later lectures. The new lectures will cover ChatGPT's latest core features, such as advanced voice conversation mode, Tasks, and Projects, in detail, in a way that can be immediately applied to practical work. We will do our best to provide you with a better learning experience. Please feel free to let us know if you have any questions or additional feedback!
