Raw network stuff is not the only area area in which that author
displays complete ignorance along with complete certitude.

Gamasutra.com appears to be some kind of trade rag.  If you need
puerile nonsense stated authoritatively, the technical and semi-technical
trade rags are where you should look.  Remember how many years the
network trade rags assured us that CSMA/CD collisions generally consume
a large fraction of the available bandwidth, evidently without ever
doing the obvious computation, at, for example 100% collisions.
And never mind their unending 30% nonsense.
