I think the author is saying that there ARE solutions, but none of them are really viable.

Seeing the future obviously can't happen. Building a higher capacity network is just wasted money. Breaking NN is going to be unpopular, not to mention determination of "not latency sensitive" is going to be difficult to impossible unless there's a "not latency sensitive" flag on TCP packets that people actually use in good faith. And flooding the network with more redundant packets is just going to be a colossal waste of bandwidth and could easily make congestion issues worse.
