In most cases, streaming is basically no different than downloading, right? The vast majority of people watch a video only once.
So it's more like saying "downloading is 90% of their traffic and its not sustainable."

If you're trying to optimize for efficient use of limited bandwidth, unicast transferring of identical content to many many people is pretty wasteful. I think Netflix would argue that network links should be getting bigger and fatter to render the point moot, but given the streams are also getting bigger (we didn't always stream 720p everywhere, did we?) that would certainly take a lot more investment than what's happening now.
