1-2g2b3 Computational universality is about computers inside our physical world being related to each other under the universal laws of physics to which we (thereby) have access (because human brains are computers)
1-2g2b4 The universality of computation is a property of hardware and rather uncontroversial. The universality of explanation is a property of software and rather controversial.
Maybe Everett needs to expand what he means by computer, just as he expanded his definition of mind by using Dark Matterdevelop

- What can be measured can be copied, and vice versadevelop
