Well, this is going to be more of a philosophical answer than a technical one: with the popularity of YouTube nowadays, which is available on every platform and allows for anyone, anywhere to instantly watch a video, the cat-and-mouse DRM game would not succeed. I think DRM is flawed (insert the typical lock-and-key analogy here) but it does work for some situations. For YouTube: probably not. Somewhere, someone talented would crack it and tools like youtube-dl would continue to exist. A recent example is youtube-dl using rtmpdump when available to download DRMed videos.
