Of course it is, but I'm a functionalist

I'd like to offer a counterargument, that, I'll admit, can get into some pretty gnarly philosophical territory quite quickly.

Premise 1: We are not simulated minds—we are real, biological observers.

Premise 2: We can treat ourselves as a random sample drawn from the set of all conscious minds, with each mind weighted by some measure—i.e., a way of assigning significance or “probability” to different observers. The exact nature of this measure is still debated in cosmology and philosophy of mind.

Inference: If we really are a typical observer (as Premise... (read more)

This sounds like another crazy thing that the logic says is right but is probably not right, but I don't know why.

Also, does this imply that a technologically mature civilization can plausibly create uncountably infinite conscious minds? What about other sizes of infinity? This, I suppose, could have weird implications for the measure problem in cosmology.

I'm not sure if I understand, but sounds interesting. If true, does this have any implications for ethics more broadly, or are the implications confined only to our interpretation of computations?

Maybe. But what do you mean by, "you can narrow nothing down other than pure logic"?

I interpret the first part—"you can narrow nothing down"—to mean that the simulation argument doesn't help us make sense of reality. But I don't understand the second part: "other than pure logic." Can you please clarify this statement?

Thank you, I feel inclined to accept that for now.

But I'm still not sure, and I'll have to think more about this response at some point.

Edit: I'm still on board with what you're generally saying, but I feel skeptical of one claim:

It seems to me the main ones produce us via base physics, and then because there was an instance in base physics, we also get produced in neighboring civilizations' simulations of what other things base physics might have done in nearby galaxies so as to predict what kind of superintelligent aliens they might be negotiating with b

I think I understand your point. I agree with you: the simulation argument relies on the assumption that physics and logic are the same inside and outside the simulation. In my eyes, that means we may either accept the argument's conclusion or discard that assumption. I'm open to either. You seem to be, too—at least at first. Yet, you immediately avoid discarding the assumption for practical reasons:

If we have no grasp on anything outside our virtualized reality, all is lost.

I agree with this statement, and that's my fear. However, you don't seem to be bot... (read more)

I have to say, quila, I'm pleasantly surprised that your response above is both plausible and logically coherent—qualities I couldn't find in any of the Reddit responses. Thank you.

However, I have concerns and questions for you.

Most importantly, I worry that if we're currently in a simulation, physics and even logic could be entirely different from what they appear to be. If all our senses are illusory, why should our false map align with the territory outside the simulation? A story like your "Mutual Anthropic Capture" offers hope: a logically sound hypot...

This is an interesting observation which may well be true, I'm not sure, but the more intuitive difference is that SSA is about actually existing observers, while SIA is about potentially existing observers. In other words, if you are reasoning about possible realities in the so-called "multiverse of possibilities," than you are using SIA. Whereas if you are only considering a single reality (e.g., the non-simulated world), you select a reference class from that reality (e.g., humans), you may choose to use use SSA to say that you are a random observer from that class (e.g., a random human in human history).

You are describing the SIA assumption to a T.

This is what I was thinking:

If simulations exist, we are choosing between two potentially existing scenarios, either I'm the only real person in my simulation, or there are other real people in my simulation. Your argument prioritizes the latter scenario because it contains more observers, but these are potentially existing observers, not actual observers. SIA is for potentially existing observers.

I have a kind of intuition that something like my argument above is right, but tell me if that is unclear.

And note: one potential problem with your reasoning is ... (read more)

I think you are overlooking that your explanation requires BOTH SSA and SIA, but yes, I understand where you are coming from.

Other people here have responded in similar ways to you; but the problem with your argument is that my original argument could also just consider only simulations in which I am the only observer. In which case Pr(I'm distinct | I'm in a simulation)=1, not 0.5. And since there's obviously some prior probability of this simulation being true, my argument still follows.

I now think my actual error is saying Pr(I'm distinct | I'm not in a simulation)=0.0001, when in reality this probability should be 1, since I am not a random sample of all humans (i.e., SSA is... (read more)

True, but that wasn't my prior. My assumption was that if I'm in a simulation, there's quite a high likelihood that I would be made to be so 'lucky' to be the highest on this specific dimension. Like a video game in which the only character has the most Hp.

But, on second thought, why are you confident that the way I'd fill the bags is not "entangled with the actual causal process that filled these bags in a general case?" It seems likely that my sensibilities reflect at least in some manner the sensibilities of my creator, if such a creator exists.

Actually, in addition, my argument still works if we only consider simulations in which I'm the only human and I'm distinct (on my aforementioned axis) from other human-seeming entities. So the 0.5 probability becomes identically 1, and I sidestep your argument. So... (read more)

I don't understand. We should entertain the possibility because it is clearly possible (since it's unfalsifiable), because I care about it, because it can dictate my actions, etc. And the probability argument follows after specifying a reference class, such as "being distinct" or "being a presumptuous philosopher."

You are misinterpreting the PP example. Consider the following two theories:

T1 : I'm the only one that exists, everyone else is an NPC

T2 : Everything is as expected, I'm not simulated. 

Suppose for simplicity that both theories are equally likely. (This assumption really doesn't matter.) If I define Presumptuous Philosopher=Distinct human like myself=1/(10,000) humans, then I get in most universes, I am indeed the only one, but regardless, most copies of myself are not simulated.

I don't appreciate your tone sir! Anyway, I've now realized that this is a variant on the standard Presumptuous Philosopher problem, which you can read about here if you are mathematically inclined: https://www.lesswrong.com/s/HFyami76kSs4vEHqy/p/LARmKTbpAkEYeG43u#1__Proportion_of_potential_observers__SIA

Thank you Anon User. I thought a little more about the question and I now think it's basically the Presumptuous Philosopher problem in disguise. Consider the following two theories that are equally likely:

T1 : I'm the only real observer

T2: I'm not the only real observer

For SIA, the ratio is 1:(8 billion / 10,000)=800,000, so indeed, as you said above, most copies of myself are not simulated. 

For the SSA, the ratio is instead 10,000:1, so in most universes in the "multiverse of possibilities", I am the only real observer.

So it's just a typical Presumptuous Philosopher problem. Does this sound right to you?

Yes okay fair enough. I'm not certain about your claim in quotes, but neither am I certain about my claim which you phrased well in your second paragraph. You have definitely answered this better than anyone else here.

But still, I feel like this problem is somehow similar to the Presumtuous Philosopher problem, and so there should be some anthropic reasoning to deduce which universe I'm likely in / how exactly to update my understanding. 

I suspect it's quite possible to give a mathematical treatment for this question, I just don't know what that treatment is. I suspect it has to do with anthropics. Can't anthropics deal with different potential models of reality?

The second part of your answer isn't convincing to me, because I feel like it assumes we can understand the simulators and their motivations, when in reality we cannot (these may not be the future-human simulators philosophers typically think about, mind you, they could be so radically different that ordinary reasoning about their ... (read more)

That makes sense. But to be clear, it makes intuitive sense to me that the simulators would want to make their observers so 'lucky' as I am, so I assigned 0.5 probability to this hypothesis. Now I realize this is not the same as Pr(I'm distinct | I'm in a simulation) since there's some weird anthropic reasoning going on since only one side of this probability has billions of observers. But what would be the correct way of approaching this problem? Should I have divided 0.5 by 8 billion? That seems too much. What is the correct mathematical approach?

Good questions. Firstly, let's just take as an assumption that I'm very distinct — not just unique. In my calculation, I set Pr(I'm distinct | I'm not in a simulation)=0.0001 to account for this (1 in 10,000 people), but honesty I think the real probability is much much lower than this figure (maybe 1 in a million) — so I was even being generous to your point there.

To your second question, the reason why, in my simulator's earth, I imagine the chance of uniqueness to be larger is that if I'm in a simulation then there could be what I will call "NPCs." Peop... (read more)

My argument didn't even make those assumptions. Nothing in my argument "falsified" reality, nor did I "prove" the existence of something outside my immediate senses. It was merely a probabilistic, anthropic argument. Are you familiar with anthropics? I want to hear from someone who knows anthropics well.

Indeed, your video game scenario is not even really qualitatively different from my own situation. Because if I were born with 1000 HP, you could still argue "data from within the 'simulation'...is not proof of something 'without'." And you could update you... (read more)
