Indeed, people seem to overlook the fact that superhuman intelligence already exists as human organizations. A company has the institutional knowledge to create things that no individual human could ever come close to, and many of them have the narrow focus of theoretical "paperclip maximizers." These organizations even have the ability to use there superhuman ability to improve themselves, and do to a certain extent, but they don't create the cartoonish runaway feedback loop people imagine. Reality ends up being a lot more difficult than handwaved fiction.
The idea of an AI apocalypse has become the quasi-religious dogma of certain groups, but it overlooks the real issues we face. I suppose when you see something everyday, it's easy to ignore its extraordinary nature.
