The Unbearable Slowness of Being: Why do we live at 10 bits/s?

Human behavior processes information at only 10 bits per second, despite sensory systems gathering data at a billion times that rate. This discrepancy raises questions about brain function and our limited processing speed. Scientists wonder why the brain needs billions of neurons to process so little information and why we can only focus on one thing at a time. The brain seems to have two modes: a fast "outer" brain for sensory and motor signals, and a slower "inner" brain for behavioral control.
