Sometimes when I have nothing better to ponder, I think about how amazing it is that communication cable run under the ocean. I'm not kidding, I've spent hours thinking about this. How did they get them down there? How do they make repairs? What do the fish think? It keeps me occupied because it is so incomprehensible.
I'm glad I'm not the only one who finds this fascinating. GOOD magazine has an article entitled Where Does the Internet Come From? which addresses how amazing our reliance on the semi-archaic submarine cable system is.
"And, while the internet might seem like the cutting edge of technology, it’s interesting to note that information has been traveling this way since the first telegraph cables were laid across the Atlantic ocean in the 19th century."
