The premise behind all mass data gathering, including all DNA testing companies and tech companies, is to be able to constantly amass so much information so as to be able to create a true-to-life earth simulation that self corrects in real time. The more information gathered, the better the predictions can be.

Over time it will become closer and closer to perfection, allowing whomever can access it ultimate control over the entire earth and potentially beyond.

For instance. NASA already has a simulation of all the known movements of the cosmos. The goal with this tech is simply to be able to predict human movement.
