Would heaven be boring?
No. A repaired world keeps every difference that can live alongside the others, and loses only the ones that survive by pushing harm onto somebody else. Cultures, languages, animals, personal memory, art, humor, temperament and local style all stay. Domination, deception, cruelty, falsified records and enforced silence go, because each of them holds together only by exporting repair work to other observers. Leibniz asked what the best possible world would be and paired simple laws with rich consequences. A blank peace would be a poor endpoint, since erasing differences would destroy the richness the whole process exists to preserve. A repaired world also keeps memory and relation, and it keeps novelty, because restored observers go on writing new records, and each one adds a fact the world did not have before.

This answer comes from OPH, Observer Patch Holography. OPH is a rigorous, consistent and complete description of the unified, self-creating computational Universe we inhabit. Its consistency is machine-checked: the fixed point at its core is constructed explicitly, and a theory with a model contains no contradiction.
To understand OPH and check every step yourself, start with the free book Reverse Engineering Reality. It builds the theory from the ground up, and the OPH Notebook answers your questions while you read.
