If roads are more intelligent than people, then why do they need constant maintenance? Why aren't cockroaches stockpiling Twinkies for when there is a nuclear war that only they will survive? Cockroaches don't plan ahead because they don't know what's coming, Rainman never figured anything out that he hadn't memorized beforehand (imagine him doing an analogy), and some people have well-rounded intelligence and seem to be able to do ANYTHING they set their minds to while others are more focused (perhaps due to obsession, specialization, laziness, life's circumstances/opportunities, psychological issues, stupidity(dumbasses exist)...) - just because someone is good at one thing doesn't mean that he is intelligent.
I don't see why anyone is confusing survival with intelligence. Whether or not something has a longer half-life doesn't imply greater intelligence. Intelligence simply means being able to figure out logical solutions to problems. I don't know why the author is trying redefine intelligence, which, as another poster pointed seems to have been quite trendy for quite some time.
