I read and reread the first page of this paper and I can't figure out what they're saying. What's new here?
I.e. for a computer analogy, this isn't showing the scale of internal wiring for a chip, or even cables on the scale of hooking the motherboard to a hdd. It is showing the wiring on the scale of 'from one rack in a sever room to another across the room'. Or, for a highway analogy, not the housing subdivisions, more the freeways.

I haven't completely read it, but that data looks more noisy than that medical express link. That makes me trust it more. I (did?) wonder whether Science would do April fool's jokes, or whether the authors made a deal to do so, with the article itself being real.
