Humans are at risk from an unaligned AI not because of our atoms being harvested but because the resources we need to live will be harvested or poisoned, as briefly described by Critch.
Be wary of taking the poetic analogy of "like humans to ants" too far and think that it is a literal statement about ants. The household ant is the exception not the rule.
Our relationship to an unaligned AI will be like the relationship between humans and the unnamed species of butterfly that went extinct while you were reading this.
I think the example of humans militaries to ants is a bit flawed, for two main reasons.
1. Ants don't build AGI - Humans don't care about ants because they're so uncoordinated in comparison, and can't pose much of a threat. Humans can pose a significant threat to an ASI - building another ASI.
2. Ants don't collect gold - Humans, unlike ants, control a lot of important resources. If every ant nest was built on a pile of gold, you can best believe humans would actively look for and kill ants. Not because we hate ants, but because we want their gold. An unaligned ASI will want our chip factories, our supply chains, bandwidth, etc. All of which we would be much better off keeping.
Early rationalist writing on the threats of unaligned AGI emerged out of thinking on GOFAI systems that were supposed to operate on rationalist or logical thought processes. Everything is explicitly coded and transparent. Based on this framework, if an AI system operates on pure logic, then you'd better ensure that you specify a goal that doesn't leave any loopholes in it. In other words, AI would follow the laws exactly as they were written, not as they were intended by fuzzy human minds or the spirit animating them. Since the early alignment researchers could figure out how to logically specify human values and goals that would parse for a symbolic AI without leaving loopholes large enough to threaten humanity, they grew pessimistic about the whole prospect of alignment. This pessimism has infected the field and remains with us today, even with the rise of deep learning with deep neural networks.
I will leave you with a quote from Eliezer Yudkowsky which I believe encapsulates this old view of how AI, and alignment, were supposed to work.
Most of the time, the associational, similarity-based
architecture of biological neural structures is a terrible
inconvenience. Human evolution always works with neural
structures - no other type of computational substrate is
available - but some computational tasks are so ill-suited to the
architecture that one must turn incredible hoops to encode them
neurally. (This is why I tend to be instinctively suspicious of
someone who says, 'Let's solve this problem with a neural net!'
When the human mind comes up with a solution, it tends to phrase
it as code, not a neural network. 'If you really understood the
problem,' I think to myself, 'you wouldn't be using neural
nets.') - Contextualizing seed-AI proposals
A different argument why instrumtal converge will not kill us all. Isn't it possible that we will have a disruptive, virus-like AI before AGI?
I agree with the commonly held view that AGI (i.e. recursively improving & embodied) will take actions that can be considered very harmful to humanity.
But isn't it much more likely that we will first have an AI that is only embodied without yet being able to improve itself? As such it might copy itself. It might hold bank accounts hostage until people sign up for some search engine. It might spy on people through webcams. But it won't go supernova because making a better model than the budget of Google or Microsoft can produce is hard.
And if that happens we will notice. And when we notice maybe there will be action to prevent a more catastrophic scenario.
Would love to hear some thoughts on this.
Uhm, I don't think anybody (even Eliezer) implies 99.9999%. Maybe some people imply 99% but it's 4 orders of magnitude difference (and 100 times more than the difference between 90% and 99%).
I don't think there are many people who think 95%+ chance, even among those who are considered to be doomerish.
And I think most LW people are significantly lower despite being rightfully [very] concerned. For example, this Metaculus question (which is of course not LW but the audience intersects quite a bit) is only 13% mean (and 2% median)
Humans are dangerous while they control infrastructure and can create more AGIs. Resolving this issue specifically by taking the toys away, perhaps even uploading the civilization? Seems unnecessarily complicated, unless that's an objective.
Then there're the consequences of disassembling Earth (because it's right here), starting immediately. Unless leaving humans alive is an objective, that's not the outcome.
I think there's a key error in the logic you present. The idea that a self-improving AGI will very quickly become vastly superior to humanity is based on the original assumption that AGI will consist of a relatively compact algorithm that is mostly software-limited. The newer assumption is vastly slower takeoffs, perhaps years long, but almost certainly much larger than seconds, as hardware-limited neural network AGI finds larger servers or designs and somehow builds more efficient hardware. This scenario puts an AGI in vastly more danger from humanity than your fast takeoff scenario.
Edit: this is not to argue that the correct estimate is as high as 99.999; I'm just making this contribution without doing all the logic and math on my best estimate.
"But I don't get the confidence about the unaligned AGI killing off humanity. The probability may be 90%, but it's not 99.9999% as many seem to imply, including Eliezer."
I think that 90% is also wildly high, and many other people around think so too. But most of them (with perfectly valid criticisms) do not engage in discussions in LW (with some honourable exceptions, e.g. Robin Hanson a few days ago, but how much attention did it draw?)
I agree that AGI is possible to make, that it eventually will become orders-of-magnitude smarter than humans, and that it poses a global risk if the alignment problem is not solved. I also agree that the alignment problem is very hard, and is unlikely to be solved before the first AGI. And I think it's very likely that the first recursively-self-improving AGI will emerge before 2030.
But I don't get the confidence about the unaligned AGI killing off humanity. The probability may be 90%, but it's not 99.9999% as many seem to imply, including Eliezer.
Sure, humans are made of useful atoms. But that doesn't mean the AGI will harvest humans for useful atoms. I don't harvest ants for atoms. There are better sources.
Sure, the AGI may decide to immediately kill off humans, to eliminate them as a threat. But there is a very short time period (perhaps in miliseconds) where humans can switch off a recursively-self-improving AGI of superhuman intelligence. After this critical period, humanity will be as much a threat to the AGI as a caged mentally-disabled sloth baby is a threat to the US military. The US military is not waging wars against mentally disabled sloth babies. It has more important things to do.
All such scenarios I've encountered so far imply AGI's stupidity and/or the "fear of sloths", and thus are not compatible with the premise of a rapidly self-improving AGI of superhuman intelligence. Such an AGI is dangerous, but is it really "we're definitely going to die" dangerous?
Our addicted-to-fiction brains love clever and dramatic science fiction scenarios. But we should not rely on them in deep thinking, as they will nudge us towards overestimating the probabilities of the most dramatic outcomes.
Overestimating a global risk is almost as bad as underestimating it. Compare: if you’re 99.99999% sure that a nuclear war will kill you, then the despondency will greatly reduce your chances of surviving the war, because you'll fail to make the necessary preparations, like acquiring a bunker etc, which could realistically save your life under many circumstances.[1]
The topic of surviving the birth of the AGI is severely under-explored, and the "we're definitely going to die" mentality seems to be the main cause. A related under-explored topic is preventing the unaligned AGI from becoming misantropic, which should be our second line of defense (the first one is alignment research).
BTW, despondency is deadly by itself. If you've lost all hope, there is a high risk that you'll not live long enough to see the AGI, be it aligned or not.
