 * "Computations" aren't exactly a low-level physical property of the universe: the same systems can be interpreted as "computing" many different things.
 * This leads to a number of [[confusing]] scenarios - for example, a [[homomorphically encrypted]] computation may or may not be conscious, but this cannot be tested externally, creating moral problems.
+  * You can check externally if you have a key. What happens if the key is deleted? What if it is not deleted, but is very difficult to obtain (timelock encryption)?
 * There is also the problem of measuring "how much" consciousness is happening: for example, what happens if I run a conscious mind on a pair of computers in lockstep, and then disable one half? What if instead of disabling one half, it is instead subjected to slightly different stimuli?
 * "Incidental computations" by all kinds of systems should plausibly be creating consciousness in very strange scenarios. Why do we experience a rulebound, consistent, simple universe? See also [[Boltzmann brains]].
 * What if I represent my computable, conscious function as a very big lookup table?
