Cyberspace is at the bottom of the ocean

"The world of cyber is going to dominate thinking and investment in a significant way over the next few years. Cyber, as many folks would look at it, if you look at the ubiquitous power point slides that have a little lightning bolt going up to the satellites and running around down to earth. That’s not cyber space. Cyber space is on the bottom of the ocean because 95 percent of what moves in cyber space moves on cables that rest on the bottom of the ocean. That’s the maritime domain. That’s the domain of the United States Navy. And the entire undersea area or resources, I believe the resource competition in the future will also drive what we do and where we do it."
