YouTube has become a worse place to learn from. The videos are longer than they need to be and are filled with ads. I am tired of sitting through 40 minutes of a video just for what is probably 10 minutes of real information. NotebookLM (Gemini Notebook) is actually a really good video converter with zero ads. It turns a fluffy video into something you can listen to or a video that stays on point, without any ads at all.
