I should add a caveat: I do expect bandwidth and latency to be issues for some customers, at least in the short term. As more resource-demanding packets demand attention, more will be lost or delayed where there are still significant bottlencks.

Going forward, in general I see the employment opportunities to be in:

-fiber. Still lots to roll out (a la Verizon in the US)

-switches/hubs. Still too much legacy equipment in the mix. Upgrades are still required.

-service. As usual. And current service people need retraining.

-writing. Hey, someone has to communicate all this stuff to the masses.
