Wikileaks and released reports are best examples of thermodynamic laws stating that everything in the universe has a tendency towards disorder. Examples are various. When a water pipe breaks, water leaks. When glass is broken glass pieces are dispersed. When you do not clean your appartment the pleace will be a mess. Secret reports have a tendency to disseminate too.
Only, DNA gets against this rule. DNA creats itself from scratch and then organizes an individual. The individuls organize a living ecosystem etc, etc..
When DNA is decoded and its magice is understood life will not be a secret anymore.
Eventually, dna information will leak to the public away from the academic platform. That is inevitable.
We will know whether a diplomat is trustable or not at the DNA level.
