Each individual human doesn't know everything that happens, consciousness + culture just makes it look like they do, as demonstrated in numerous comments in this thread, and all other threads, on TV, in conversation, etc. Reality itself is composed of various mirages.

Your brain is the most powerful filter we've discovered in the universe. You can take immense amount of noise and separate information from it. The issue with these filters is most of the time you don't realize you have them. How you were raised, the people you're around, the culture you're in can all present bias filters that are impossible to see around since you don't even realize they exist.

It may not be 'figuring it all out', but sometimes just having a filter lowered for a bit letting you realize there is another part of the world exists behind it can be a breakthrough.

But on second thought, we certainly are experiencing some kind of phenomenon of consciousness, even if it's purely an emergent phenomenon of the physical world. And tweaking the experiencing of that consciousness will tend to expose the boundaries of it, even if just at the level of running a fuzzer on a C program or blowing up a balloon too far.
