As technology advanced and the world became more connected, the way people formed social groups changed over time. Originally, people clustered into "geographical tribes" based on their physical location, as this dictated the shared norms and objective reality of that group. Later, as mobility increased, people began forming "sociographical tribes" around shared social classes and interests, allowing for some choice in social identity. Now, with global connectivity, people can form "psychographical tribes" based solely on personal beliefs and affinities, rejecting imposed identities. This empowerment of individual identity and ability to connect with others worldwide on that basis represents the final stage in humanity's social evolution.
