I'd argue that we think about them more than we used to, what with the current war on the continent and the threat of Russia cutting our cables at any time.

Though still, not as much as we should be thinking about them for sure, but I wouldn't say never.

They're basically completely unprotected, and Russia, or any major nation or very well funded organisation, could easily rig explosives to all of our manor cables (there aren't that many), and set them all off on the same day.

Which would bring chaos the likes of which we have never seen. We live in the Information Age, after all.
