The challenge of understanding the epigenome is daunting, however, since every person—and every cell within that person—has a unique epigenome of flipping gene switches ON or OFF. The combination or pattern of which genes are ON and which are OFF is huge and has an effect on our health and well-being. In computer terms we have a huge network of switches set in different orders from another human. One day we may be able to map these networks and determine which diets affect which diseases but the work is enormous.  Neural Networks are well-known in artificial intelligence computers.

Are we just computers? Is our DNA simply a type of hardware? Is our epigenetics the software that programs who we are? Is disease programmable? How can we un-program it? These are important questions in modern Biology today. Over the next decade we will hear much about epigenetics and nutrigenomics. They may become household terms. Our children will not feel they are pre-programmed by their DNA but look to how they can have positive changes to their epigenetics.

History shows us that the dinosaurs were wiped out by a large meteor. That event clearly didn’t kill off all life. In fact mammals adapted to the environmental changes, mutated, became intelligent and thus here we are today. If we blow ourselves up or are killed by another cataclysmic meteor, we may end our existence but some other animal or plant life will adapt its DNA and become intelligent and rule for a while. It is a cycle.
