The funny part:  Those on this list who have cited Moore's Law don't seem to
have an understanding that it does not directly apply to custom routing
logic (since general-purpose CPUs are no longer fast enough to do the
lookups on the high end).  In addition, GP CPUs are no longer scaling
exponentially, but rather closer to quadratically and approaching linear.

In short, Moore's Law is dying, and even if it weren't, it is not a valid
argument for "let the swamp in".
