You can buy a brand new bicycle for $14,000

but you can't drive that on a freeway. And you can't drive a Segway on
the freeway either.

Back in the 1930's, something called radio was developed into a
business. There were popular music programs and radio dramas. Today, in
the UK admittedly, I have a digital radio on which I can listen to
popular music programs and radio dramas. In fact, when I switched from
analog to digital I got a wider choice of stations to listen to. There
is a metaphor in here somewhere, for the IPv4 to IPv6 transition.
