Abstract:

Metcalfe's Law basically tells us that as you connect n number of machines you get n squared in potential value. So, with 2 machines you get a value of 4. When you connect 10 machines, you get a value of 100. When you connect 200 machines, you get a value of 40,000. People like to apply this idea to the internet. In particular, people claim that the strength of the internet is a direct result of so many machines being connected. I think that this is bullshit.
