Gary Marcus hasn't changed his tune since 2016. Yet a bunch of progress has been made since then!

Is DL a reasonable path to strong AI? Probably not. DeepMind is making cool stuff in game playing, but it's still "dumb" AI.

But Marcus has cornered himself as a professional skeptic of deep learning. A voice which is useful only at times.

Re:Deep learning is hitting a wall? by idealmedtech on Wednesday March 09, 2022 @10:33PM (#30622967)
I think he does offer some compelling arguments in this article, worth at least examining rather than dismissing based on his past skepticism. Particularly about the potential harmony between deep learning and symbolic manipulation, which is enormously difficult (a far cry from the set-and-forget style that has taken DL so far), but perhaps cracking AGI will require us to do a little more difficult work. I'd love to be proved wrong here, though! My depth of understanding on DL is pretty shallow.

We are a very long way from even having 0.0001% of the compute required to produce a weak AGI.

like everything, it will take much more resources and time than we can predict today with our best estimates, partly because that's just how these things turn out, and mostly because a true AGI will likely require billions of neural networks all adapting and swapping neurons and communications pathways amongst themselves and training themselves at the same time they are doing useful work.

we have no idea how to do anything like this at scale, yet.

Re:Deep learning is hitting a wall? by p1esk on Thursday March 10, 2022 @03:03AM (#30624381)

DeepMind managed to rekt the best players in Go and StarCraft after a few years of founding. Go has been played for 3000 years, and it has influenced military strategy since ancient times. The strategies you can find in Sun Tzu's Art of War were influenced by the game of Go.

Did you know what is the difference between the military simulators used by defense departments and strategy games like Go? Did you know both share a lot in common? What you dismiss as "game playing" has more present applications than you imagine and will make the difference between life and death in armed conflicts.

The orders given by generals will likely come from a successor of MuZero. And that may expand to every key decision making process, like the equipment to be manufactured, logistics, etc.

Combine that with the power asymmetry coming from drones and that "game playing" will become the most dominant force in this world.

As I'm reading it, the argument isn't that progress can't be made or cool things can't be done with these tools. It's that for certain problems no amount of progress will be sufficient, yet we have entire domains of the tech and consumer products industries built around and selling the idea that just a little bit more will get us there.

The argument is compelling to me and fits my experiences. I think the limitations of these tools has become more apparent to non-specialists the last couple years, so if he's been saying this since 2016 that's honestly more impressive. What do you expect him to change his tune to if he's already singing a good one?

In mathematics, you solve problems from both directions, at times.

It seems that computer science has come full circle with psychology, finally.

Dig into computational comparative psychology for leads on where deep learning experts need to turn to next.

There are plenty of computational neuroscientists that are probably struggling with untwining what they are looking at.

Of course strong AI is possible; most people can make one with 18 years and a willing partner.

It just doesn't scale.

It doesn't scale in the "I want twice as many, right now, to use, abuse, and discard without guilt or strings attached".

9 women do not a baby in 1 month make. Once you have said bab(y|ies), you then have the inconvenience of them having a will of their own, you have to support and eventually pay them, and dear god, make too many of them and they might even just throw you away instead of going in the direction you want.

That kind of not scaling.

I mean... If no one else is willing to say it, I'll call a spade a spade; because that is precisely the major draw of the computer as ecpnomic/logistical lubricant. Doing jobs of people, but not getting paid or having to be accounted for as one.

The only thing that meets this definition of scaling is our fantasies. Absolutely everything else uses resources implying an opportunity cost and has non-zero latency in making any desired change.

Re:Deep learning is hitting a wall? by salawat on Friday March 11, 2022 @10:06AM (#30640774)
How many IBM mainframes get paid and are given the capability to allocate their own capital?

How many of the computers we use to program transaction processors and other things are seperate from the entities that operate them? How many human actors were displaced, and salaries saved by cutting of jobs we've automated away?

We look at vehicle automation, machine learning, etc... Precisely because they open up new avenues through which money can be saved by not employing as many expensive bags of carbon and water in favor of throwing a handful of graphics cards, sensors, hard drives, and compute resources at problems that like it or not, we required fleets of humans for previously.

If it weren't in some fashion more economically viable at some level, in some way, I'm fairly sure we wouldn't still be pursuing it.

That's the thing I've noticed. It's the grim version of the more rosey "we're empowering fewer people to do more with less."

If we manage to create an artificial sentience then we need to legislate and protect their rights. AGI won't be a free lunch.
Re:Deep learning is hitting a wall? by drdeca on Thursday March 10, 2022 @12:09AM (#30623433)
Just because something is AGI probably needn't imply that it is sapient. It might have no internal experience, no feeling of desire, only a utility function which it optimizes.
Re:Deep learning is hitting a wall? by krageon on Thursday March 10, 2022 @05:34AM (#30625348)
This reasoning is why it will need rights. If it doesn't, people thinking these thoughts (which are impossible to answer, like they are for every other potential sapience. Not just AGI) will abuse that reasoning to create yet another creative modern form of slavery.
Re:Deep learning is hitting a wall? by drdeca on Thursday March 10, 2022 @09:49PM (#30635549)
I do agree that it probably makes sense to err on the side of being too quick to estimate that something is likely sapient than to err on the side of being too slow to do so.

However, that doesn't make it impossible for a plan-producer to be both superhuman and non-sapient.

Nor do I think the default is for an AGI to be sapient.

(Though, possibly the default could be such that it isn't but in a way in which we couldn't be sufficiently confident that it isn't, and therefore be obligated to behave as if it is sapient)

But, in the FOOM scenario, I would expect that "whether or not to treat it as if it has rights" would be the least of our worries. (the greatest of our worries would be, roughly, "whether it kills everyone".)

Re:Deep learning is hitting a wall? by unlikelymordant on Wednesday March 09, 2022 @11:57PM (#30623378)
Honest question, why would we need to do that? They arent human or animal, it seems to me like saying we need to protect the rights of chairs or PCs. I personally think letting AI have e.g. property rights would be catastrophic if you can just spin up another one.
Re:Deep learning is hitting a wall? by drdeca on Thursday March 10, 2022 @12:08AM (#30623426)
Whether an AGI should have rights depends on the specifics of the AGI.

Being capable of acting in general environments, planning and taking actions in the world, etc. I think probably aren't in themselves enough for the agent to have moral patienthood.

But, that's not to say that it wouldn't be eventually possible to make an AI which was a moral patient (like, suppose it was not just able to plan taking itself and its own planning capabilities into account, but was in addition, also sapient, in the sense of having an internal experience like that of our own. In this case (e.g. perhaps a computer emulation of a human mind) then I'm fairly confident that such an agent would be a moral patient. Such an agent being copyable as data would no more prevent them from being a moral patient than having a magic duplicator ray which could duplicate a living human including their body, would render all people not moral-patients, namely, not at all.)

edit: that's not to say that it wouldn't be catastrophic, but, having such a duplicator ray might also be catastrophic for the same reasons, and the presence of such a magical duplicator array shouldn't render all people suddenly not moral-patients, and so the copyability of AIs shouldn't by itself prevent them from being moral patients either.

Re:Deep learning is hitting a wall? by unlikelymordant on Thursday March 10, 2022 @12:55AM (#30623635)
If there was a magical duplicator ray, governments would want to heavily regulate its use. A few million extra bodies would completely crash an economy, but might be good if you wanted to fight a war.

I do think the duplicator ray is a great analogy. There would be a lot of tricky moral questions raised if such a technology existed.

On the topic of a human mind in a computer, i dont think they should be afforded property rights either. If you can copy them into 10 bodies, and each one can own a house, then they are taking real resources from actual humans. This extends to owning other things too.

Re:Deep learning is hitting a wall? by virchau13 on Thursday March 10, 2022 @01:52AM (#30623860)
> then they are taking real resources from actual humans.

But who is "they"? If you copied them 10 times, it's not like they act as a collective; there are 10 unique instances having unique experiences. What's wrong with 10 different people each owning a house?

Re:Deep learning is hitting a wall? by krageon on Thursday March 10, 2022 @05:36AM (#30625361)
"they" refers to the collective other: Something that is vaguely understood as not being like you, without having a clear definition. It is a linguistic way to alienate something so it becomes okay to treat it poorly without inconvenient feelings of guilt.

I suspect these statements are contradictory. What is an "actual human", anyway? Next you'll be trying to tell me that entities without souls don't need rights. How do we detect souls? Well, you kind of just know.

Re:Deep learning is hitting a wall? by lumost on Thursday March 10, 2022 @12:12AM (#30623446)
The answer depends on whether we would have absolute authority over an AGI's motivations, interests, and decisions. If the AI is extracted from any human derived data-source, this is unlikely to be the case.

An AGI which demonstrates sentience and its own independent wants/needs would raise substantial ethics questions if not afforded some rights.

Re:Deep learning is hitting a wall? by unlikelymordant on Thursday March 10, 2022 @12:28AM (#30623517)
I guess the question is what rights. I think property rights should be off the table. Right to life? Humans get killed by the state if they break the law. Right to not be retrained? Is an ai that has its weights updated still the same ai or a different one? My opinion is that humans and human civ (this includes e.g. a healthy planet that can support us) should always come first. Do you have an idea of what right s you think an ai should have?
Re:Deep learning is hitting a wall? by 2muchcoffeeman on Thursday March 10, 2022 @01:29AM (#30623773)
Surely if we give "life" to something with all the capabilities of a human brain, then it should get all the same rights as us? I mean, if a human broke their neck and literally only their brain worked are they any less human? Human babies are also helpless but they have rights too.

Then I think you'd have to work your way down from there. We'd have to really ensure that these things have no capacity for learning, emotions or pain if we want to abuse these things with no ethical qualms.

> Surely if we give "life" to something with all the capabilities of a human brain, then it should get all the same rights as us?

I dont think this is as axiomatic as people think. Why should we give them rights? Should a program be able to own a house and displace a human? If they are effectively immortal, can continously learn, and consistently act logically, giving them human rights will eventually force humans into an underclass, because we dont have those advantages (i understand this is a bit hyperbolic).

If you are interested in equity at all between humans an AI, i think you have to take into account the advantages an ai might have and give humans a lot more rights to counteract those advantages.

Re:Deep learning is hitting a wall? by 2muchcoffeeman on Thursday March 10, 2022 @04:33AM (#30625017)
I think the place to start is if this life we created has certain traits we consider human. Creativity, ability to suffer, empathy. If we cover some of these things you’d have a major ethical problem in not giving them any rights.

>i think you have to take into account the advantages an ai might have

Yes. No disagreement there.

There is a slight ambiguity in 'last', which might mean either 'most recent' or 'final'.

The difference here is that while karpierz's last step is, at least for now, the final one in a process producing a strong, generalized, self-awarely-conscious theory-of-mind-holding intelligent agent, the evolution of DL systems has not yet done so.

We have a pretty poor understanding of how the human brain (our only "Strong AI" evidence) learns, but the one approach that has been pretty definitively ruled out is large-scale backpropagation in the style that most deep learning pursues today. Maybe backprop is a true alternative approach to AGI, but it's hard to be completely convinced of this.

Just finished reading the article, interesting points.

I agree that there’s too much emphasis on the “robot”, but coming from an academic background in mathematics and psychology (and biology), I cannot take PDP as anything other than “this is how brains work”. Granted, half of PDP, the book, is a series of examples of “ways it might work” from 40 years ago or so, but the other half is about fundamentally tying the psychology to the brain through parallel distributed processing as a conceptual framework.

In that sense, I don’t think PDP can be refuted any more than token economies or political polling can be refuted.

Thoughts?

In the meantime, I will bookmark your thesis for perusal.
