[A great paper ...]

The Internet [...] is stupid. On purpose. Its designers made sure the biggest, most inclusive network of them all was dumb as a box of rocks.

The Internet doesn’t know lots of things a smart network like the phone system knows: Identities, permissions, priorities, etc. The Internet only knows one thing: this bunch of bits needs to move from one end of the Net to another.

There are technical reasons why stupidity is a good design. Stupid is sturdy. If a router fails, packets route around it, meaning that the Net stays up. Thanks to its stupidity, the Net welcomes new devices and people, so it grows quickly and in all directions. It's also easy for architects to incorporate Net access into all kinds of smart devices — camcorders, telephones, sprinkler systems — that live at the Net's ends.
