IF WE USE ONLY THE TIP OF THE ICEBERG OF OUR BRAINS, surely the inevitable development of a cultured Bio-Brain could represent the most complex and potentially powerful computer ever devised, assuming you could access the entire system. The human brain is the most complex system of neural connections and functioning biological entity that Nature has yet evolved. It is almost a Sci-Fi fantasy to imagine the possibilities. The ancient Egyptians, during mummification, would remove the brain, typically discarding it, while preserving other organs; today, nothing will go to waste.
