A little while back I posted a talk with Vint Cerf about the internet today and tomorrow, and at the risk of repeating myself, here is another. Although they cover essentially the same ground I believe they are sufficiently different to be worth posting separately. For me, the most intriguing thing here is the discussion of interplanetary communication protocols. Maybe these could one day complement or completely replace IP addresses. Evidently I do not know the specifics – or if they are even really appropriate – but imagine a system of networking that starts with the assumption that every person and every object produced from now on (not to mention billions of sensors introduced to monitor or control existing infrastructure) would want to be connected to the internet and that the system should be able to scale so that allocation of addresses is effectively infinite.
Vint Cerf is always interesting and eloquent, and as you can see, gets you thinking too.
