Chaos is very hard to explain, and in terms of regular understood commonly used language, it tends to be connoted negatively.
Hard to explain? That depends. I can make it simple and say that chaos is the opposite of order. And the connotation, positive or negative, depends on the type and kind of order we compare it to. I can easily imagine a kind of order compared to which chaos is to be preferred; some accelerationists think that way... In fact we define all things by what they are not; we know what's a chair because it's not a table or a space-ship. We also know that we've evolved to crave order; pattern-recognition is one our prime talents, so much so that we seek patters everywhere, sometimes to our detriment, but mostly to our advantage.
