The most dedicated students don't need to download the video. They watch it, take notes, recreate the lessons in their own projects, and let the stream evaporate. They trust their own synthesis. The downloader, conversely, often hoards. The 500GB folder of "saved courses" becomes a monument to procrastination, a library of unread books.

So before you click "download," pause. Ask yourself: Are you trying to own the video? Or are you trying to own the skill? One is a battle against DRM. The other is a battle against yourself. And only one of those battles can be won.
