But the capacity of the Internet is constantly need, with miles and miles of unused fiber waiting to be lit.

Any work done on QOS will just help for a little while until things get too congested, then the QOS algorithms will do more harm then good, and they probably won't scale to new transport technologies, nor new uses of IP connectivity.

If the same effort went into increasing capacity, then the QOS would be unnecessary. Working on QOS only helps a small percentage of traffic work a bit talk for a small increase in utilization.

Routinely, we have increased capacity by factors of 10 through new technology, and there is no reason to believe this will stop.

Complicated QOS techniques can slow the creation of newer, higher capacity transports that would lessen the need for QOS in the first place.
