The problem I see with streaming is that content encoding technologies are always a bit ahead of content delivery technologies.
When was the last time we could say: oh, the delivery tech has waaay more bandwidth than the source?
So unless Quantum-EtherealNet is developed (BTW- I own the TM on that name
) in the next couple of decades, and it is available everywhere (which it should, it's quantum AND Ethereal), then I just don't see how streaming will ever keep up.
Today, streaming sucks, and sucks big. Not the least because not everyone has 50 Mbps fiber going into the home (and an ISP that supports true max speed).
Good 1080P requires a steady 15Mbps or better.
We're about to get an uptick in video bandwidth demand with 4K resolution content just around the corner. By the time streaming has real, honest 1080p, most videophiles will be buying the 4K BluRay discs.
