Interesting description of worldview. It somewhat equates to people
who understand dimensional data representation: linear, matrix and
database. I can do the first two quite easily (think a flat file
document versus a spreadsheet). Where I lose confidence is with
But I did get the answer to the exponential problem because I worked
the logic backwards. That's fine for analysis after the fact. You
know the result: the rats filled the room at a particular time. (What
wasn't said was that was the exact time that the room filled and
there was an absolute filling and rats don't squash, because if they
did, the filling could have happened before the 1pm time given.) But
in the real world, we don't know the end point of that filling. So
then the whole thing falls into a risk management and diversification
of investment space.
We've had a bit of exploration on link about the value of redundancy,
a type of diversification (of access/service). We didn't have much
redundancy before the mobile network, but now it's expected. So do we
pull out the alternative connections? (copper and wifi in areas that
can use fibre) Is it economically justifiable to maintain? Do you
mothball these so there is a backstop?
Aggregation is another aspect of this: if you put all the comms on
the fibre to a particular house (I'm not talking about the range of
install for the particular range of houses by using wireless and
satellite), and that single connection goes out, you lose the
channels of communication. If TV goes to all-wired in the future,
shut down the open broadcast towers, or radio goes all online instead
of open airwaves because those frequencies can be better used for
something else, then we are at risk.
Phasing out (exponentially?? ;-) ) is another consideration in the system.

Our truest response to the irrationality of the world is to paint or
sing or write, for only in such response do we find truth.
