I think that even exploiting software and hardware bugs everywhere to gain total computing dominance should be excluded.

I appreciate your general point, but on this specific one ... "the internet of things" really does mean "eternal unfixable Heartbleed everywhere". Your DSL modem is probably a small Linux box, whose holes will never be fixed. When the attacker gets that box, >90% of fixed PCs are still running Windows. Etc. As a system administrator, I can quite see the modern network of ridiculously 'sploitable always-connected hardware as a playground for even a human-level intelligence, artificial or not, on the Internet. It is an utter, utter disaster, and it's only beginning.
