I do think we need to redefine [network] operations, which is not an architect, it's operations. Right now, we do a lot of [network operations] manually. And if you automate it, you no longer have to do it manually. But that doesn't mean people's jobs go away. It just means it changes. Just like what happened with server virtualization; you don't need to rack and stack as much, but you need to understand how to deploy and manage and troubleshoot the software.
So I think there is a shifting of responsibility and roles. But these are all going to be redefined. And, to your earlier point about who's nervous, everyone is nervous.
