I assume (6) means that your “anthropic update” scans across possible universes to find those that contain important decisions you might want to influence?
Yes, and then outputs strings from that set with probability proportional to their weight in the universal prior.
By (3) do you mean the same thing as “Simplest output channel that is controllable by advanced civilization with modest resources”?
I would say “successfully controlled” instead of controllable, although that may be what you meant by the term. (I decomposed this as controllable + making good guesses.) For some definitions of controllable, I might have given a point estimate of maybe 1 or 5 bits. But there has to be an output channel for which the way you transmit a bitstring out is the way the evolved consequentialists expect. But recasting it in these terms, implicitly makes the suggestion that the specification of the output channel can take on some of the character of (6′), makes me want to put my range down to 15-60; point estimate 25.
instead of using (1)+(2)+(3) you should compare to (6′) = “Simplest program that scans across many possible worlds to find those that contain some pattern that can be engineered by consequentialists trying to influence prior.”
Similarly, I would replace “can be” with “seems to have been”. And just to make sure we’re talking about the same thing, it takes this list of patterns, and outputs them with probability proportional to their weight in the universal prior.
Yeah, this seems like it would make some significant savings compared to (1)+(2)+(3). I think replacing parts of the story from being specified as [arising from natural world dynamics] to being specified as [picked out “deliberately” by a program] generally leads to savings.
Then the comparison is between specifying “important predictor to influence” and whatever the easiest-to-specify pattern that can be engineered by a consequentialist. It feels extremely likely to me that the second category is easier, indeed it’s kind of hard for me to see any version of (6) that doesn’t have an obviously simpler analog that could be engineered by a sophisticated civilization.
I don’t quite understand the sense in which [worlds with consequentialist beacons/geoglyphs] can be described as [easiest-to-specify controllable pattern]. (And if you accept the change of “can be” to “seems to have been”, it propagates here). Scanning for important predictors to influence does feel very similar to me to scanning for consequentialist beacons, especially since the important worlds are plausibly the ones with consequentialists.
There’s a bit more work to be done in (6′) besides just scanning for consequentialist beacons. If the output channel is selected “conveniently” for the consequentialists, since the program is looking for the beacons, instead of the consequentialists giving it their best guess(es) and putting up a bunch of beacons, there has to be some part of the program which aggregates the information of multiple beacons (by searching for coherence, e.g.), or else determines which beacon takes precedence, and then also determines how to interpret their physical signature as a bitstring.
Tangent: in heading down a path trying to compare [scan for “important to influence”] vs. [scan for “consequentialist attempted output messages”] just now, my first attempt had an error, so I’ll point it out. It’s not necessarily harder to specify “scan for X” than “scan for Y” when X is a subset of Y. For instance “scan for primes” is probably simpler than “scan for numbers with less than 6 factors”.
Maybe clarifying or recasting the language around “easiest-to-specify controllable pattern” will clear this up, but can you explain more why it feels to you that [scan for “consequentialists’ attempted output messages”] is so much simpler than [scan for “important-to-influence data streams”]? My very preliminary first take is that they are within 8-15 bits.
I also don’t really see why you are splitting them [(4) + (5)] apart, shouldn’t we just combine them into “wants to influence predictors”? If you’re doing that presumably you’d both use the anthropic prior and then the treacherous turn.
I split them in part in case there is there is a contingent of consequentialists who believes that outputting the right bitstring is key to their continued existence, believing that they stop being simulated if they output the wrong bit. I haven’t responded to your claim that this would be faulty metapyhsics on their part; it still seems fairly tangential to our main discussion. But you can interpret my 5 bit point estimate for (5) as claiming that 31 times out of 32 that a civilization of consequentialists tries to influence their world’s output, it is in an attempt to survive. Tell me if you’re interested in a longer justification that responds to your original “line by line comments” comment.
