Seems to me like a great signal to use. So if you're getting links from sites with no traffic, they're not worth anything

Yes, that seems to be the very best signal to me. Been thinking about that for 6 months now at least. Haven't been able to prove it with testing or anything, but surely they will be using that more and more.

But I do think that if and when Google implemented/implements this patent, it'll mean an end to SEO as we know it

Na, just that the rules are changing (as always), and we'll use different tools. Like spending more time pursuing links that send traffic as well as PR/link juice. And making sites stickier. And making the outgoing links more enticing to click, so visitor doesn't hit the "back" button.
