Unfortunately, their 2040 number is based on an assumption that bandwidth
will continue to increase, but that media capacity won't.
Andrew Tanenbaum makes another of those points in his "Computer
Networks" is responsible for another such (this in a ref to a diagram of

much. df/dLambda = -1 * (c / (lambda*lambda))
Which basically says that people who believes wireless
radio-telecommunication can compete against optics in pure thruput is
smoking.
