You never really think about it but it's pretty wild. Several hundred cables are all that connects us to other continents.

10 terabits per second- hell, anybody could get anything done with that kind of speed. Run an Empire on a 4-channel telgraph, then get back to me...
I know we'll always need the ol' inteweb "backbone". But I wonder if we'll see a day where the wireless signal is as fast as a wired connection. Imagine not needing a wired connection at home. Just a small router that picks up a 4G(or faster) signal and all the devices in your house are internet connected.

Some issues with some of the cables in Japan after the earth quake and I was reading somewhere about some dredge fishing boats off Korea/China that were causing havoc on the underwater cables. Would certainly be a neat documentary to see how those are laid out and maintained.

No. There isn't enough wireless spectrum to ever go faster wireless than what is possible going wired. To get to where we are now with wireless, (LTE, WiMAX, and 802.11n WiFi using QAM modulation), we're running multiple channels in parallel.
"Fast" costs money when you're running over licensed radio spectrum since somebody has to pay the billions for the license & radio infrastructure and you have to share it with all the other users sharing your antenna. To reduce the number of users sharing a single antenna, you bunch the antennas much closer together and reduce the power so they don't interfere with each other. That makes the radio network really expensive.
With COAX or fiber, you can deliver 100 gigabit/sec if you want to. That would never be possible with wireless.
