network.  Keeping the costs down on end user hardware is fundamental, and
those devices will behave however they want (ie badly).  AQM is the
'roundabout' that keeps things flowing but each thing at an appropriate
rate so it works well.  There will *never be infinite bandwidth or even
enough that no services saturate it.   Even a very small town with everyone
on a 1G turns into 20Tb of necessary capacity to avoid the usefulness of
AQM.  When likely 20Gb is sufficient.

There has to be something that addresses the car going 180MPH on the
freeway.  That car requires everyone else to pull off the road to avoid
disaster in the same way that data chews up a fifo buffer and wrecks the
rest.  AQM is the solution now, and more evolved AQM is most likely the
answer for many many years to come.
