Hey Eric,

I would go as far to say that even if somebody gives you *free* 40G
equipment in the year 2022 you shouldn't use it, because it's a
technological dead-end and becomes a huge bother when you need to interface
with some newly purchased device on the other end of the 40G circuit.


Then you went too far. For many users the 40G port is there to increase 10G
density, by offering 4x10GE breakout. It is already difficult to support
1GE customers and 10GE is starting to become problematic. But SP networks
actually have these customers, and not every application on the Internet
will always need more and more capacity, so many of these customers have no
requirement to ever purchase faster ports.

If you live in cloudyworld, sure, denser and faster. But this mode of
thinking is making life at SP networks rather difficult.
