Your Consciousness Is Ten Seconds Behind the PresentS

The time it takes for sensory input to travel along nerves and get processed by the brains means we're always living in the past. Okay, no problem — we can live with a few lost milliseconds. But ten seconds? A new study shows that once our brains make a decision (like "push this button") it takes that long for our conscious minds to become aware of it.

Neuroscientists at the Max Planck Institute for Human Cognitive and Brain Sciences in Germany conducted the study, and appear concerned that people will feel robbed of their free will. Interesting, but the real question is: Once brain-computer interfaces are developed for the masses, are we going to need the plodding "consciousness" part of our brains at all?
