30,000 hours is about the amount of new video uploaded to YouTube every hour.

That's astonishing. If you watched all of them, how much new information would you learn? I suspect a large portion of them are the same information presented differently; for example a news story duplicated by hundreds of different channels.

It's a huge amount of video-game footage included in those "hours of video uploaded per-hour".

So very, very little new info will be conveyed by the vast majority of the content.

Yeah, I imagine every moment of communication a child receives is new information not just baby talk about getting the spoon in their mouth and asking them if they have pooped.
