 * {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 one half being disabled, it is 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]].

 * "[computationalism] means that there are certain combinations of numbers which suffer when written down or thought about, which is an absurd idea if you ask me"
