There's a happy medium in there somewhere; it's not clear that having (to
use the examples given) air traffic control computers directly on the
Internet has sufficient value to outweigh the risks.  However, it seems
that being able to securely gateway appropriate information between the 
two networks should be manageable, certainly a lot more manageable than
the NxM complexity involved if you try to do it by securing each and
every Internet-connected ATC PC individually.

It sucks in some ways, but providing a limited number of pathways in that
are under tight, secure control is a desirable goal.  If you give the PC
that allows control of the power grid access to the Internet so that the
operator can "efficiently" update his Facebook while he's simultaneously
controlling the power grid, that's hazardous, and no amount of snide
remarks about job creation will change that reality.

These networks ought to be air gapped to the maximum reasonable extent
possible; all pathways in ought to be defended as though they were the
gateway to the kingdom.
