I don't see #1 affecting decision making because it happens no matter what, and therefore shouldn't differ based on our own choices or values. I guess you could argue it implies an absurdly high discount rate if you see the resulting branches as sufficiently separate from one another, but if the resulting worlds are ones I care about, then the measure dilution is just the default baseline I start from in my reasoning. Unless there is some way we can or could meaningfully increase the multiplication rate in some sets of branches but not others? I don't think that's likely with any methods or tech I can foresee.

#2 seems like an argument for improving ourselves to be more mindful in our choices to be more coherent on average, and #3 an argument for improving our average decision making. The main difference I can think of for how measure affects things is maybe in which features of the outcome distribution/probabilities among choices I care about. 

I think there's a problem with the entire idea of terminal goals, and that AI alignment is difficult because of it.

"What terminal state does you want?" is off-putting because I specifically don't want a terminal state. Any goal I come up with has to be unachievable, or at least cover my entire life, otherwise I would just be answering "What needs to happen before you'd be okay with dying?"

An AI does not have a goal, but an utility function. Goals have terminal states, once you achieve them you're done, the program can shut down. An utility function goes on forever. But generally, wanting just one thing so badly that you'd sacrifice everything else for it.. Seems like a bad idea. Such a bad idea that no person has ever been able to define an utility function which wouldn't destroy the universe when fed to a sufficiently strong AI.

I don't wish to achieve a state, I want to remain in a state. There's actually a large space of states that I would be happy with, so it's a region that I try to stay within. The space of good states form a finite region, meaning that you'd have to stay within this region indefinitely, sustaining it. But something which optimizes seeks to head towards a "better state", it does not want to stagnate, but this is precisely what makes it unsustainable, and something unsustainable is finite, and something finite must eventually end, and something which optimizes towards an wards an end is just racing to die. A human would likely realize this if they had enough power, but because life offers enough resistance, none of us ever win all our battles. The problem with AGIs is that they don't have this resistance.

The after-lives we have created so far are either sustainable or the wish to die. Escaping samsara means disappearing, heaven is eternal life (stagnation) and Valhalla is an infinite battlefield (a process which never ends). We wish for continuance. It's the journey which has value, not the goal. But I don't wish to journey faster.

It's not my field of expertise, so I have only vague impressions of what is going on, and I certainly wouldn't recommend anyone else use me as a source.

That makes sense. Are there any promising developments in the field of AI safety that make you think that we will be able to answer that question by the time we need to?

You are making an error here: ZFC + not Consistent(ZFC) != ZFC. 

Assuming ZFC + not Consistent(ZFC) we can prove Consistent(ZFC), because inconsistent systems can prove everything and ZFC + not Consistent(ZFC) + Consistent(ZFC) is, in fact, inconsistent. But it doesn't say anything about consistency of ZFC itself, because you can freely assume any sufficiently powerful system instead of ZFC. If you assume inconsistent system, then system + not Consistent(system) is still inconsistent, if you assume consistent system, then system + not Consistent(system) is inconsistent for reasoning above, so it can't prove whether assumed system is consistent or not.  

I am asking this, because I am planning on entering the field, but this is a pretty niche topic that I haven't yet researched.

I meant that they were functionally booleans, as a single condition is fulfilled "is rich", "has anvil", "AGI achieved". In the anvil example, any number past 1 corresponds to true. In programming, casting positive integers to booleans results in "true" for all positive numbers, and "false" in the case of zero, just like in the anvil example. The intuition carries over too well for me to ignore.

The first example which came to mind for me when reading the post was confidence, which is often treated as a boolean "Does he have confidence? yes/no". So you don't need any countable objects, only a condition/threshold which is either reached or not, with anything past "yes" still being "yes".

A function where everything past a threshold maps to true, and anything before it maps to false, is similar to the anvil example, and to a function like "is positive" (since a more positive number is still positive). But for the threshold to be exactly 1 unit, you need to choose a unit which is large enough. 1$ is not rich, and having one water droplet on you is not "wet", but with the appropriate unit (exactly the size of the threshold/condition) these should be functionally similar.

I'm hoping there is simple and intuitive mathematics for generalizing this class of problems. And now that I think about it, most of these things (the ones which can be used for making more of themselves) are catalysts (something used but not consumed in the process of making something). Using money to make more money, anvils to make more anvils, breeding more of a species before it goes extinct.

Great post! 

In the past, broad interventions would clearly have been more effective: for instance, there would have been little use in studying empirical alignment prior to deep learning. Even more recently than the advent of deep learning, many approaches to empirical alignment were highly deemphasized when large, pretrained language models arrived on the scene (refer to our discussion of creative destruction in the last post).

As discussed in the last post, a leading motivation for researchers is the interestingness or “coolness” of a problem. Getting more people to research relevant problems is highly dependent on finding interesting and well-defined subproblems for them to work on. This relies on concretizing problems and providing funding for solving them.

This seems be a conflicting advice to me. If you try to follow both you might end up having hard time finding direction for research. 

Thanks for making the game! I also played it, just didn't leave a comment on the original post. Scored 2751. I played each location for an entire day after building an initial food stockpile, and so figured out the timing of Tiger Forest and Dog Valley. But I also did some fairly dumb stuff, like assuming a time dependence for other biomes. And I underestimated Horse Hills, since when I foraged it for a full day, I got unlucky and only rolled a single large number. For what it's worth, I find these applet things more accessible than a full-on D&D.Sci (though those are also great), which I often end up not playing because it feels too much like work. With applets you can play on medium-low effort (which I did) and make lots of mistakes (which I did) and learn Valuable Lessons about How Not To Science (which one might hope I did).

The second reason that I don't trust the neighbor method is that people just... aren't good at knowing who a majority of their neighbors are voting for. In many cases it's obvious (if over 70% of your neighbors support one candidate or the other, you'll probably know). But if it's 55-45, you probably don't know which direction it's 55-45 in.

My guess is that there's some postprocessing here. E.g. if you assume that the "neighbor" estimate is wrong but without the refusal problem, and you have the same data from the previous election, then you could estimate the shift of opinions and apply that to other pools that ask about your vote. Or you could ask some additional question like "who did your neighbours vote for in the previous election" and compare that to the real data (ideally per county or so). I would be very surprised if they based the bets just on the raw results.
