I'm talking of the revolutionary quality of digitization. And I say it's revolutionary because once information is no longer a bunch of box files or papers in a filing cabinet but just bits that fly through the air, it means that it's so hard for people in power to control it. And it's always been true that knowledge is power. And so once it becomes very difficult for people in power to keep hold of information it means that it becomes very hard for them to keep hold of power, because power just flows out. The default now is zero cost for information to spread instantly around the globe. And in fact you have to pay money to stop it now. That's incredibly disruptive and revolutionary.
