I am going to divide what I say into three themes.

What is the Internet?

Permitted or licensed versus Permissionless Speech

Expanding the scope of licensed speech

What do I mean by "the Internet"

I would say that the Internet has proven to be a kind of Esperanto for machines, permitting them to communicate with each other despite different internal operating systems.

The Internet accomplished this by what engineers envision as a layered architecture of machine languages, called protocols.

The core protocols of the Internet separated what we now call the applications from the transport layers below them. This was its most significant innovation.

Three effects have flowed from this separation of application from transport.
