I see no reason to consider the so-called Principle of Computational Equivalence of philosophical interest with respect to natural objects like brains.
Given a natural entity or process x and a computation of it c(x) it does not follow that c(x) = x. It does matter whether x = an organic apple or an organic brain.
c(x) = x iff x = a true digital artifact. It seems to me that we have no reason to suppose except as a matter of religious faith that any x in the natural world actually exists as a digital artifact.
For example we might in principle create perfect computations of hurricanes. It would not follow that hurricanes do computations.
