Running a server from your home violates the terms of service of many ISPs (they want you to upgrade to a more expensive business plan for that). I’m not sure that is going to change in 10–20 years. Nor do I think router storage space is going to get significantly larger in the next decade, at least not in terms of being able to host large videos.
It probably depends upon which ISP you have and how "big" or "small" they are. I know 3 families who run their own servers from the home internet plan. Though they use it mostly from small sites and not for anything big/commercial.
