Indeed.

I agree with this wording.

I don't think we have much maneuvering room though; the benefits of
Moore's law helping building faster routers are more or less offset by
the same Moore's law helping building more bandwidth-hungry consumer
devices. In other words, growth of the DFZ table has to rely on router
enhancements, not on riding Moore's law.

There is no such thing as "PI for everyone" in the foreseeable future.

Michel.
