Quantum measurement leads to branching in the Many Worlds Interpretation (MWI), creating multiple realities where different outcomes coexist. Each measurement results in a split, with observers experiencing only the outcome relevant to their branch, while other branches exist independently. This branching process creates numerous versions of individuals, but they do not interact or share experiences across branches, maintaining distinct identities. The discussion highlights the challenges of reconciling MWI with traditional notions of identity and consciousness, emphasizing that each observer perceives their own continuous stream of consciousness. Ultimately, MWI suggests that while many versions of "you" exist, they are not copies but rather separate entities with unique experiences.
