I read many distinguished colleagues speculating about how may jobs may be created via high-speed networks.
I would like to stress that, in order not to undermine such potentials, new high-speed networks should be rellay open, i.e. they should not be able to discriminate/differentiate the services running over them. The history of the Internet is a good example: for ages telcos have been managing pipeline, however the invention and the launch of the Internet was due to non-telcos guys. The same can be said about the most popular Internet services of the web: Google, Facebook ecc. If telcos have had the possibility to choose or influence which kind of services may be available, no innovation would have been flourishing. In Italy, the first ISPs were brought to bankruptcy by the dominant telco which was worried about the declining of the fax business (replaced by electronic mail).
Telcos are always tempted to say that, since they are investing in infrastructures, they want some money coming from the service providers, however you could see this reasoning fron another perspective: nobody would pay for a crappy BB service unless you can get some smart services. The booming of Internet mobile data of the last years is a confirmation of that: such growth has been driven by devices, services and applications, not by connectivity offer (which was there from a decade).
