There are 8 billion people. If half of them were awake, and 10 percent of that half are actually typing at 40 words/minute, that would be about 13Gbit/s. I couldn't receive that feed today at home, but my work could. A satellite feed could work today too. And I wasn't really talking about today, but 10-20 years from now. Storage will be a problem for a lot longer than network capacity.

Storage grows geometrically, while network capacity has grown less so. It's possible we will soon have more storage than humans can create content to fill. No problem; automated systems also fill storage!
