The topic of this study is implementing a globally available, centralized knowledge base, which can be accessed and searched online via a brain interface for everyone. Our goal is to describe this plan, first analysis from the side of society. After this, we try to present how the actual form of this knowledge base was developed from the Time Begins to the present. At the end of the study, we describe two ways: the most pessimistic and the most optimistic ones, their odds, and the facts which increase the realization of odds.  This study was carried out at the University of Debrecen, in the „Time capsule 2016+20” project as part of the Program for Talented Students (DETEP) program.
