Humans aren't like animals. The individuality makes us humans, otherwise we would be sheep (I don't know why sheep get such a bad rep but we would be).
Swarm intelligence is a bad idea. Even if it would make us more intelligent we would lose individuality which in my view is more important. It could only be good if it was a proper peer-to-peer collective of individual minds, like Bitcoin pretty much is.
I completely agree with you. You do not need to strive to make people out of smart Zombies that you can control, that's just the name that they will be intelligent will be mediocre because individuality involves free thinking and freedom of choice.
