We turned off analogue TV despite some objections.

But that had a government imposed deadline, funding and people
in a body created to see through the transition, and an industry
looking for the benefits of more people on the new platform
which allowed more channels so more market.

Can enough upsides be put in place to make IPv6 fly?

Better user tracking has been over taken by privacy concerns

Larger market is not desired by the incumbents who think
they own it all already and don't want easier competition.

This is global not national, things are a lot easier at
national scale. Could the countries with national firewalls
switch them to NAT64 while only filtering v6, though
this route would end up with more countries with firewalls
so probably not a good plan, and it has failed in previous tries.

Too long and people will leave it until later. There
has to be some peril to get it into the next refresh rather
than leave to future ones.

It does feel like a transition method should be agreed and a
timeline started. By who?
