In 50 years, human civilization will have the technology to "obliterate themselves", that is to painlessly destroy all pieces of individual memories and behavior that one has to do in order to join the collective human hive mind, an ultra-intelligent network of minds implanted in each obliterators' consciousness, that sees the universe in a reality much truer than how a normal human sees it.
The collective hive mind is a collection of minds with a priority to the most rational concepts and beliefs, extracted from all individuals who underwent the process of obliteration, done in order to ascertain the true nature of reality.
