At a biological level, the individual has not changed. However, the reaction times, emotional, and behavioural vectors measured by the network have provided both the individual and the group with a level of self-knowledge never before available in previous eras. When the Knowledge Network became universal, data sheets were published for everyone, which were maintained by personal assistants. The primary reference point classified people's abilities in four dimensions, and the results measured in each category were indicated by letters. A+ was the best, while D- was the worst. The individual categories referred to the following:
- Logical intelligence
- Emotional intelligence
- Physical intelligence
- Social intelligence
Although the classification was continuously criticized by everyone, its ease of use provided a good overview of individuals. Data collection was continuous, however, the city, based on its own values, or the individual could decide on its publication to a certain extent. If someone did not make their own data available, they could not see others' either. Young people could decide on this issue at the age of twenty; until then, they could not see their results in these categories.
The data sheet not only collected data related to the above categories but also health and interest data. The assistant indicated to the individual if it saw any behavioural or health changes or trends that could become dangerous for the individual in the long term. The central computer was able to model society from the collected data by involving the individual level, and tried to make suggestions so that the whole could achieve the common societal goal.
Family
The idea of traditional, everlasting families had fallen into pieces even before the Great Migration. Economic and biological development made it an individual decision who, how, and when one practiced intimacy. The infections that destroyed everyone were over, as was unwanted pregnancy.

Society accepted that people invited each other not only for coffee but also for longer or shorter intimate encounters.
All this was not mandatory, and it was still not public. In the developed Western world, the population dropped so drastically that decision-makers did everything possible to ensure that parenthood was not experienced as an obstacle by parents. The larger community participated in the safe upbringing of offspring in an unprecedented way. Those who had children also received extra material and physical support, if requested or needed. The burden associated with parenting was intended to be reduced in this way.
The Great Migration, which fundamentally shook all societies, disrupted families even more. The majority of families became broken. But with the help of technology, people quickly found suitable groups for themselves and relied on them to survive everyday life. With the restoration of production and the cessation of economic coercion, large families were replaced by loosely connected, but very reliable groups that satisfied people's desire for community belonging. The family ceased to exist and expanded to the group at the same time.
Society
The societies of Earth significantly intermingled during the Great Migration. A unified basic language, a uniquely mixed but quite simplified version of English and Chinese, was spoken worldwide. Cities could retain and develop their own layered languages, as well as their customs and values. However, none of these could go against the global values of humanity. Thus, they could not over-utilize their resources, waste and pollute the environment, or build group self-awareness based on the hatred of others. The network monitored the observance of the rules.
Society considered its fundamental task to be enabling humanity to leave the Solar System, and create the possibility of safe living either in space or on another planet.
At the same time, this goal was viewed as something that should not limit individual freedom and well-being, as long as it did not go against the aforementioned frameworks. The achievement of the goal was planned to last for approximately five hundred years.
In addition to its self-restraint, society invested enormous energy in increasing the number and quality of interactions among its members. It actively sought forms and opportunities to introduce unknown members of society to each other to stimulate the emergence of new ideas and break through the bubble effect that automatically forms in communities. Such programs included travel support for young people and organizing visits to other families during the adults' virtual travels.
