The big deal about the internet design was you could have arbitrary large number of networks so that they would all work together. And the theory we had is that if we just specify what the protocols would look like and what software you needed to write, anybody who wanted to build a piece of internet would do that and find somebody who would be willing to connect to them. Then the system would grow organically because it didn’t have any central control.
And that’s exactly what happened.
