If we form multiple worlds via decoherence, then the worlds are, by definition, orthogonal, so there is no possibility of their ever recombining. David Deutsch got this wrong many times. Quantum computers work by interference of qbits -- so they must all exist in the same world. A conscious quantum computer does not experience other worlds.
