The definition of fitness for DNA also originated outside it, so this doesn't in itself suggest the system isn't actually creating new knowledge.

A person could create the same knowledge that biological evolution does, if only by simulating it. But it could still be true that only people can create explanatory knowledge. (That they can create all possible explanatory knowledge is Deutsch's criterion for personhood.)

"No unconscious creativity" seems the simpler option. But here we arrive again at biological evolution, which is unconscious, yet is creating knowledge. Does this serve as a distinction between explanatory knowledge and non? Explanatory knowledge can only be created by a conscious process?

Either there is no unconscious creativity, or only evolutionary/creative epochs with certain properties are conscious. The most obvious candidate for the property is complexity (in the sense of sophistication): only programs (existing knowledge) of a certain sophistication, once subjected to the evolutionary process, necessitates consciousness. Complex problem solving seems to require consciousness. Meanwhile, we do not seem to be conscious of "simpler" creative tasks, like... Like what? What is a "simple" creative task? What is an example of a creative task we perform unconsciously? How could we determine it was an act of creation (new knowledge), and not an act of deductive inference of the kind characterizing AI?

This suggests that all experience is determined by what programs are being subjected to evolution at any given time, the niches that are being adapted to. But why is not all creativity in the mind conscious? (All consciousness might necessarily be creativity).

But if the evolution is the defining feature of personhood, and the evolution is non-computational, then the personhood is non-computational. And consciousness would then not be a software property.

Programs could be evolved non-computationally. But that process could itself still be simulated, per the Church-Turing-Deutsch Thesis.

By the Church-Turing Thesis, all computation can be specified/programmed. So the evolutionary aspect of a person can be specified/programmed, if it is computational.

The system may not have perfect knowledge of all programs present in it. The repeated independent emergence of winged flight in the biosphere comes to mind.

Because programs present in the system at one time could be no longer present at another time. Previously well-adapted programs could have decayed, been destroyed or consumed. So the same evolutionary path (approximately or not) could be travelled again, in principle.

Actually this is not implied. One experience and an identical later one could be caused by the same program(s) being run again at a later time; if the program which is identical to the given experience is part of an "evolutionary personhood program", that still qualifies: If the second experience is identical, under the above solution that just means that the exact same evolutionary steps are taken in the second case. Maybe this would virtually never happen, but poses no problem of principle.

By the latter standard, neither nature nor random number generators are people, which is sensible; nor can nature create any given possible knowledge tractably -- this is true because the fact that all possible knowledge exists is only by way of the multiverse, which is a process that cannot be simulated in its entirety, even by a quantum computer.

This is a bad criterion because then random program generators are sometimes people.

It is mistaken to apply probabilistic thinking to human affairs, because they involve knowledge, and the growth of knowledge cannot be predicted.

In summer in the desert, will it "probably" be sunny in the afternoon?

PROBLEM: Why are we conscious of the apple rendering? Given (6), why is there an experience of it, if the programs comprising it are looping, and so are therefore predefined?

SOLUTION: The apple programs are not the same programs one execution to the next. They are being re-evolved every time they are run. This evolution is what the person is doing, and so must be what gives rise to the experience consisting of the apple rendering.

This suggests that programs can be “run differently” to result in a different computation. This is false because it violates Substrate Independence: the instantiation of a program is unaffected by its physical implementation. If a “context” changes what the program is computing, then that’s a different program. Suggesting that a person running the apple programs “makes them” conscious therefore is not sound. The programs are either conscious or not. If they were, by (A1), they would be people.

(7) We can be conscious of the apple imagery for the entire 5 seconds.

(6) Repeated running of the same fixed program is automatic, requires no creativity, and cannot constitute experience.

(5) Repeated running of the same fixed program, not being a person, does not make it a person.

(4) The programs rendering the apple are not people, so cannot themselves constitute experience.

(3) The programs rendering the apple imagery must be looping until stopped, since they could not have advance knowledge of when the stimulus stops.

(2) The rendering is caused by the running of some number of programs.

(1) During the entire 5 seconds, your mind renders the image of the apple.
