Android and iOS already support live captions and AI Accelerators are becoming more common in PC hardware. If you can generate it with little compute at home, then there is no need to set up a share system.

You also want local generation in a lot of cases. If you have your own videos you need to generate them yourself. For Accessibility it's fantastic if they can have subtitles on every Video.

If generating your own is fast and good enough and takes little compute, then it isn't needed to share them. Having subtitles generated by the best models and optimized by humans is better, but not needed in most cases.
