AI is automation, systems of automation. People could automate to the point of leading to a constant flow of horrific things happening, creating a highly efficient war machine - whether against another nation or your own people.
From my perspective, Mark has always seemed like a controlled thinker - including controlling his actions, behaviour, etc. in a very fixed way. In contrast, Elon's always seemed to be a holistic thinker, starting from founding principles and then understanding what his actions will lead to. Elon's openness to thought leads me to believe his thinking style would lead to understanding how AI could evolve better than Mark's more controlling behaviour.
What does it mean to have an understanding of AI that's limited?
Have you ever talked to someone who is way smarter than you? Have you tried to imagine how they think? I suspect thinking about the future of AI is a little bit like that, insofar as it's hard to model the future state intelligently.
These two are very different and don't compete in the same space as Jobs vs Gates.
Musk is a generation above Zuckerberg. 13 years older. Musk is better as an innovator while Zuckerberg is better at business. Zuck has like 69 Billion while Musk has about 16 Billion
I don't trust Zuckerberg on any issue in which Facebook has much to gain from one side. We all know how much money he'd like to make by having some AI programs follow us around 24/7.
One guy is trying to change the world and one guy is trying enslave it.
When you have the likes of people like Stephen Hawking agreeing with Musk, why wouldn't you listen and be wary. Mark doesn't seem like a very intelligent person, just a very lucky person.
Musk was the guy that created a car that can track and report everywhere you go using a permanent connection to his mothership, plus films and uploads the surroundings and even has an camera inside. The only protection being his word that they won't read it unless you allow them.
Wow. Mark used an example of self-driving cars being good for humanity as his example of why AI will pose no danger; to make a point about his perspective in a feud with the guy that is leading self-driving car revolution pointing out that AI could potentially be dangerous. I hold great concerns for Facebook's future.
Seems this pivots on a disagreement of AI as a risk
Musk seems very anxious of existential threats-- it isn't surprising he may overestimate the danger of AI
It also comes off as very monkey-centric. Is it so bad if human intelligence isn't what proliferates the future? Perhaps AI is a kind of memetic evolution for our culture, evolving into a form of life which can achieve sustenance with much less waste
Elon's an open holistic thinker, his thoughts lead him to the end point of what could happen.
AI is automation, systems of automation. People could automate to the point of leading to a constant flow of horrific things happening, creating a highly efficient war machine - whether against another nation or your own people. This is likely what Elon is thinking about - other than the possibility that a real AI system is developed that is given the ability to manage resources, e.g. Ex Machina (film).
>It also comes off as very monkey-centric. Is it so bad if human intelligence isn't what proliferates the future?
For humans, it's an absolute disaster - look at what happened to the lesser apes when Homo Sapiens became dominant. The odds are very good that a sentient AI will decimate us or make us extinct, simply by adapting our habitat to its own needs.
>> It also comes off as very monkey-centric. Is it so bad if human intelligence isn't what proliferates the future?
>> Perhaps AI is a kind of memetic evolution for our culture, evolving into a form of life which can achieve sustenance with much less waste
Is that what humanity should strive for? Create form of Intelligence that can sustain itself with less waste?
Calling someone who is trying to create better future for his 5 kids "monkey-centric" is pretty offensive. I wish there were more "monkey-centric" people out there.
They're talking past each other because "AI" has become a useless term.
Musk's comments are about a potential (maybe conscious) artificial super intelligence and the risks that could come from that if we enable one somehow without understanding the preconditions.
Zuckerberg is just talking about "AI" in the sense that machine learning can solve a valuable class of problems.
The super intelligence risk could be serious or not - it's hard to know since we haven't really dealt with an intelligence that wasn't created through natural selection with those biases for survival. We also don't really understand how consciousness works either.
One risk of AI is that if Musk's argument is right we won't be as 'lucky' as we were with nuclear weapons. Enriched uranium is hard to get so nuclear weapons are easier to control and hard for an individual to make. Turning on an AI or copying the code for one and spreading it would probably be easier. If it does end up being dangerous that's not a great situation.
>Turning on an AI or copying the code for one and spreading it would probably be easiear.
What people never mention in any discussion with AI is that the AI will be as limited by physical world as we are. AI It's not just code, it's also the hardware that will run the code. That hardware has theoretical and practical limits, and requires a lot of power. It's not like AI running on some peta/exascale supercomputer will be able to jump to your laptop and take it over and spread itself to every electronic device in the world.
Exactly. And that's one big reason I find so many of these "doomsday" scenarios less than useful. They're largely based on a view of AI that's rooted in science-fiction, not reality.
It's not like AI running on some peta/exascale supercomputer will be able to jump to your laptop and take it over and spread itself to every electronic device in the world
That's exactly a proposed scenario - with the form of "jumping" being any kind of communication. See: The AI Box problem.
Or maybe it could decide to move to another universe and take it over.. There are physical limitations to what AI even in the form of super-intelligence can do. While theoretically it could distribute itself to other computers, it first would need to learn a lot everything from math to computer security, which itself would take implies that it would have unlimited resources and time to do all of that.. Even if that superAI did learn all of the skills necessary to take over many computers (it would need to learn about architectures, operating systems, firewalls, antivirus, compilers etc) it would still be limited by the latency of the network so not all operations would make sense in a distributed system. And of course it would need to be so smart that nobody would notice that there is increase of "weird" traffic on the internet, that suddenly power usage would increase as computers would do all these calculations instead of sitting idle waiting for user to open fb.com.
To take over the world such AI would need to learn everything we already know about the world, not only including math and physics, but also including sociology and human behavior. While AI would be busy taking over the world, you would have to assume that we would be sitting, doing nothing, and that we would not be smart enough to figure out that something is going on. And when we did we would do nothing to stop it.
I think the main argument against this is once you're in the world of "super intelligence" you're severely outmatched. If for some reason it had an interest in staying on it might not be easy to stop.
super intelligence will not happen overnight. AI will keep evolving with us and before it's truly conscious it will give us better understanding of math, physics, medicine.. This will help the AI grow, but at the same time we will be growing with it. It will be a symbiotic relationship.
Not necessarily, there's the idea of an "intelligence explosion" - basically that while it may take a while to figure out the initial conditions it might be able to self improve rapidly from that point. Also consciousness may not be required (or possibly even preferable).
"intelligence explosion" is also limited by the physical world. AI won't be able to come up with a better understanding of physics simply by reading academic journals. Yes it might have some good ideas, and find some of the stuff we're missing by simply connecting the dots, but that in no way will cause "intelligence explosion".
Just think how much money and time we have to spend to test just a few of all of the theories in physics. And no, AI will not be able to suddenly come up with better theories simply by simulating physical world.
But how can one think that Mark's understanding of "sci-fi AI" is limited? We're so far from any of it that at this point it's all speculation about what could or could not happen.
If I have a theory that humans will evolve into separate species, I can't say someone else's understanding on the matter is limited.
Limited in a sense that he's saying Musk is being irresponsible and then talking about the simpler machine learning problems that can be solved [1] when Musk's warning is really about the super intelligence piece.
The main problem is the term AI is overloaded and overused so it creates confusion.
Musk is not against the machine learning approach to solving a new class of useful problems (though replacing a lot of current human jobs and the political risk associated with that is an issue to think about)
It's not useless as a term but AI has become a catchall for anxiety about the future.
I'll add another set of concerns you see in these discussions.
People know that the current version of predatory Capitalism we've created so far would happily mass unemploy everyone (possibly all the white collar workers reading this much sooner then you think). This would leave no workers and no consumers with money outside of the ultrawealthy.
I agree. I don't trust the current version of capitalism to program these AI of the future. I think they will burn the house down in their greed.
I'll add another concern which is already occurring (the thing I'm concerned about, not the concern, although I guess the concern is already occurring)
AI is being used as a workaround to existing anti-discrimination laws. The core of anti-discrimination law is that it doesn't matter if you think on the average my group of people is a worse credit risk or more likely to rob your taxi or more likely to trash your rental property; you need to judge me by the risk of the general population.
AI allows you to create a black box which will inevitably find proxies for race and spit out a higher risk for some races than others. Race won't directly appear in the model but what does will be strongly correlated with race.
> We also don't really understand how consciousness works either.
Sort of a nitpick, but people concerned about AI risk usually don't postulate that an AI needs to be """conscious""" to be dangerous; it just needs to be a thing that can apply a lot of optimization power in unexpected ways toward goals that aren't perfectly aligned with what humans generally want.
... but we already have that, right? Undesirable outcomes from rulesets that govern the behaviour of a large number of (conscious or unconscious) actors are a pretty standard feature of civilisation
Yes, we do have that already, and it's kind of odd that people who see no point in thinking hard about risks to humans from this particular type of inhuman optimization process would readily agree that other types of inhuman optimization processes (with much better understood risk profiles and limitations) can be very harmful. :)
Perhaps the 'singularity' type stuff makes a lot of people disengage?
So far I'm inclined to think that the whole 'sentient AI mucking things up' is jumping the gun (to put it mildly). I might very well be wrong though.
However, it's only because of HN that I even bother to make the distinction between that particular fear (realistic or otherwise) and the much more directly useful discussion of how AI-type stuff (even just facebook feed algorithms) can be dangerous or harmful.
I don't think it's odd. I agree that optimising for the wrong thing (or, probably, for any particular thing) can be harmful, especially when it's done on a very large scale. AI-as-we-know-it doesn't introduce a new class of risk, it just makes some of the optimisations faster. I don't see any point in thinking about AGI risk until we get some experimental evidence that AGI is possible
Maybe. I think the idea is that it's preferable to have wasted a lot of effort on coming up with irrelevant abstractions addressing a nonexistent problem, than to be surprised by something weird and poorly-understood presenting novel and not-clearly-bounded risk and not have effective tools at hand to address it.
I won't claim to know what the right amount of effort directed toward this is though, nor do I really think AI safety research has a >epsilon chance of accomplishing its goal if it turns out to be relevant at all. ¯\_(ツ)_/¯
"The goal of maximizing paperclips is chosen for illustrative purposes because it is very unlikely to be implemented, and has little apparent danger or emotional load (in contrast to, for example, curing cancer or winning wars). This produces a thought experiment which shows the contingency of human values: An extremely powerful optimizer (a highly intelligent agent) could seek goals that are completely alien to ours (orthogonality thesis), and as a side-effect destroy us by consuming resources essential to our survival."
OpenAI did a thing[0] where they used a human to help train a machine learning model by picking the best of 2 models.
> Our algorithm’s performance is only as good as the human evaluator’s intuition about what behaviors look correct, so if the human doesn’t have a good grasp of the task they may not offer as much helpful feedback. Relatedly, in some domains our system can result in agents adopting policies that trick the evaluators. For example, a robot which was supposed to grasp items instead positioned its manipulator in between the camera and the object so that it only appeared to be grasping it, as shown below.
It doesn't even need to be a superintelligence - Musk explains a scenario that isn't very far on the horizon here at the Governor's meeting: https://youtu.be/OYJ89vE-QfQ?t=2959 (from 51:45 to 53:50)
I think that they're actually talking right at each other, but Zuckerberg is thinking of the possibilities, while Musk is thinking of the implementations.
"AI is the future" really means that Zuckerberg sees the massive potential of automation, and how it's going to change the face of the world.
"We should be worried about AI" really means that Musk has had to think long and hard about the fact that the software written by Tesla is navigating living human beings around obstacles at high speeds.
This isn't about some accidental super intelligence that becomes self-aware and murders all humans, it's about the consequences of applying today's standards of "let's ship this code" to technology that we're expected to entrust with our lives.
This is two things, combined: "AI" means that code will have more complex emergent behavior that's harder to debug than current code, which is already nearly impossible to completely debug. "AI" also means that this code will run very complex systems that often have powerful hardware components, unfortunately including weapons.
To put it another way: Both men agree that the code of the near future is going to make a massive leap in effectiveness and real-world applications. But Musk has to grapple with being held morally accountable for that code, while the only thing Zuckerberg's ever had to care about is performance. Say "AI" to Mark Zuckerberg and he sees all of the money in smarter data mining and fun home appliances. Say "AI" to Elon Musk and he has nightmares of deploying a wireless update that causes Teslas to confuse people wearing green clothing with green traffic lights.
Mark Recruited Yann Lecun, arguably the top "AI" practitioner in modern times (backprop anyone?). Lecun agrees with Mark and I would be surprised if Mark wasn't taking most of his direction in AI from Lecun.
Good point. Another noted expert in "AI" is Andrew Ng (formerly Google and Baidu) who stated that, "Fearing a rise of killer robots is like worrying about overpopulation on Mars."
...For some reason Elon is really hung up on gradient-based descent methods terminating all of humanity. We just aren't close to that possibility yet. It is not even in sight.
The majority of the ML field still ignores entirely the AGI discipline - and in general rightly so as there are enough narrow problems to solve to fill a lifetime. That's the perspective of Lecun/Ng etc... because they are scientists.
The others Bostrom et al. are philosophers, so they approach it from a different perspective.
There are valuable reasons to think about it at both levels.
Correct. There were plenty of economists that said Bitcoin would fail, and philosophers that thought otherwise. The jury is still out, but I know who is winning.
A majority of the experts in AI would side with Zuckerberg on this one. See for example: http://blogs.discovermagazine.com/d-brief/2017/07/18/artific.... It's not that we shouldn't worry about AI, it's that the issue Musk is raising - AI as an existential threat -, is distracting from the real issues.
"eventually" is the key word here. Most experts in the field admit to have no clue how and when these predictions will ever come true. It makes discussing them an overly speculative exercise.
> 50% of experts think there’s at least a ten percent chance of above-human-level AI coming within the next ten years.
(ten years!? sheesh)
> And 40% of experts think that there’s a better-than-even chance that, once we get above-human level AI, it will “explode” to suddenly become vastly more intelligent than humans.
> And 70% of experts think that Stuart Russell makes a pretty good point when he says that without a lot of research into AI goal alignment, AIs will probably have their goals so misaligned with humans that they could become dangerous and hostile.
> ... 5% think this is “among the most important problems in the field”. Only a tenth – 1.4% – think it’s “much more valuable” than other things they could be working on.
Not totally clear which of those Zuckerburg wouldn't agree with, but this isn't exactly a fringe concern anymore, even if most people think it's not worth thinking about yet.
Honestly I'm pretty appalled by Musk's statements. There's no indication from recent research that we're close to the "dreadful super intelligence". I think he has an a very naive and scifi-ish understanding of the state of AI and his fear mongering is irresponsible at best. Or maybe he's right and private companies are so technologically advanced that they surpass academia by a wide margin. Somehow I highly doubt that.
As overloaded as the term "AI" has become, to the point where mainstream discussion is unlikely to be substantative, I'm glad a tech-business leader like Elon Musk is at least taking a public position of some skepticism. AI can be as empowering or as dangerous as we design and constrain it -- but to a layperson, AI and "algorithms" seem like inevitable magic, in the way that iPhones have steadily "improved" in hardware specs and in life-augmenting features.
Musk's view of AI relies on AI being magic, too. He's using the definition of "AI" that exists only in hyped-up promises about the future, and evaporates when applied to present technology.
Musk dismisses AI experts who tell him that his claims bear no resemblance to real technology, because Musk isn't talking about the same AI as them. He's talking about sci-fi AI.
There are no experts in sci-fi AI because, if there were anything there that one could understand well enough to be an expert in it, it wouldn't be sci-fi AI anymore.

Different audience, different messaging.
