The sky over Buenos Aires is all over criss-crossed by interconnecting electrical cables and telephone wires as you can see in the picture. Many parts of the city seem to lack an underground wire system. Whenever someone needs broadband internet service the cable guys just throw a new cable from house to house. It is as simple as that. I find this a great example to get an idea of what the Internet looks like in 3D.
What do you think, is the Internet friend or foe?
