AlphaGo is machine learning. Machine learning is “learning from experience”. It’s empiricism. It’s impossible. Whatever is happening there, it’s not learning. No explanatory or any other alleged kind of knowledge is created.
@SimonDeDeo @wileyprof
Me neither. Finished it yesterday. Was a pain to get through.
I should add that it gets worse, though. I know some decision makers in Silicon Valley who know damn well it has nothing to do with intelligence but choose to call it that anyway because it sells. That’s fraud.
Learning is the creation of knowledge. Narrow AI is the following of predefined steps; the same as all programming so far. Using the term "learning" for something that clearly isn't learning is utterly misleading and dishonest (I'm mad at the industry, not you.)
@ChipkinLogan @scotthortonshow
Very well written. It really is denial of knowledge creation again: all the wealth is allegedly already present, just needs to be redistributed "fairly".
@onnlucky @bnielson01 @ks445599 @mizroba
Well, then maybe you should read more Popper (something I have recommended to you before).
Or at least google "Popper/Bühler four functions of language".
You will then learn that most of the things you listed require explanations, not merely descriptions.
@onnlucky @bnielson01 @ks445599 @mizroba
They're not. The point is it doesn't matter if it's vocalized or only descriptive. Popper explained that the descriptive function of language is built on top of the signaling function.
@onnlucky @bnielson01 @ks445599 @mizroba
None of the things you just listed require spoken language. The only way I can make sense of this is that you thought we were talking about programming language or something. We weren't.
@markcannon5 @bnielson01 @mizroba
Yes. Whoever builds an AGI will be its parent. His obligation will be to help it learn.
@bnielson01 @ks445599 @mizroba
Yes. Language is not required to make a universal explainer. How could it be? You need to be one in order to learn language in the first place. Again, no instruction from without possible.
Have the terms "eco-induction" or "green induction" been coined yet? Might be useful to refer to this sort of idea.
That's what this idea suggests: that there is knowledge somehow already present in the biosphere (not as adaptations!), and we just need to harvest/ingest it.
"How much do species and ecosystems contribute to the size and growth of economies?"
They don't. Only people do. And only explanations guessed by people tell us which resources, species, and ecosystems are at all relevant to economic growth. twitter.com/NaturePortfoli…
"But if [@DavidDeutschOxf] is right that evolution has led to humans as the ultimate knowers, where did this knowing arise?" from sfgate.com/opinion/chopra…
That is a problem the theory of evolution solves. David addresses it in "The Beginning of Infinity".
@ks445599 @bnielson01 @mizroba
Indeed. It could start making all kinds of conjectures about reality and criticize them. It just won't be able to test them. For example, it will know that it exists, and that therefore things can exist. It can then guess that other things might exist, too, what they may be, etc.
@bnielson01 @ks445599 @mizroba
I think you're flirting with induction here. A child does not learn to be intelligent, especially not via instruction from without. He is born intelligent. What knowledge he creates using that intelligence and whether IO may help with that are different matters.

"How can we build beneficial AGI?" is yet another "Who should rule?" question. It should be replaced with "How can we detect our errors in building AGI?" and then, once built, "How can we help AGI learn?"
Stopping doing one thing and starting doing another is easily programmed and doesn’t involve the halting problem.
It wouldn’t need to be made of DNA. If it wants to study chemical reactions they can be exosomatic.
Ah, yes. Though to be clear, an AGI running on a computer is a completely non-biological phenomenon. No genes required.
That's fine, but then I still don't understand your original comment: twitter.com/EvanOLeary/sta…
Sure. But in order to learn about music?
Why would it have to be able to perform organic chemical reaction experiments in order to be able to learn anything?
Not sure I follow. Care to elaborate? I don’t think any biological substrate is needed.

Yet they can, and frequently do, lead to death. I suspect this is similar to how genes have to keep their hosts alive but often don’t.

Thanks.
“But all we need to know is that for an expensive belief to travel through history with some population over a long period of time, it must be paying its way somehow.”
No. Static memes don’t survive by solving problems (“paying [their] way”).
@ChurchoftheSim @HeuristicWorld @ToKTeacher @reasonisfun @Crit_Rat @dela3499 @RatCritical @BretWeinstein
LOL, "rational religion". Classic example of a static meme trying to compromise, creating garbage in the process. "Sure, 100% religion is bad, but let's reduce it only to 50%" (or 20% or whatever).
@HeuristicWorld @ToKTeacher @reasonisfun @Crit_Rat @dela3499 @RatCritical @BretWeinstein
Broadly speaking: Yes, absolutely. It denies creativity by claiming that everything important that can be known is already known, it punishes dissent, creates bad explanations... in short: actively prevents progress.
I am not familiar with Weinstein's take on it.
The discovery of the equivalence of software engineering and reason, if I say so myself.

"There is no distinction between the computer and the program. They are one and the same."
Utter nonsense.
@ReachChristofer @SamHarrisOrg @DavidDeutschOxf
A correction to a mistake I made: our computers are technically not Turing complete because they have finite memory. We may choose to consider them Turing complete for practical purposes.
Any run of the mill computer also has software interacting with hardware and vice versa. It does not chance the distinction between the two.
The "neuroscience of learning": topos.house/residency.html
The brain is a computer. People learn via a program on that computer. We need to study that program, not the computer.
@aroraharshita33 @james_ough
Here's your answer: you could, but only by increasing the brain's processing speed somehow.
The second link states you're trying to understand how humans learn. That's the right question to ask, but have you looked into whether we already know a fair amount about this? (We do.)
@MartvMegen @ReachChristofer @SamHarrisOrg @DavidDeutschOxf
Yes. Can you guess why?
I was on @ReachChristofer's podcast. We spoke about evolution, knowledge, machine learning, and the benefits of building AGI - among other things.
Thanks for having me!
Yes. Computation is when you use physical objects to represent abstract ones.

I’m guessing he’s talking about weighted connections between neurons as inspired by neural networks, AKA coefficient matrix. Not about weighing ideas.
Hmm. How does one emulate it without an explanation?
You write in “Possible Minds” that “digital immortality [...] is on the horizon for humans, too, perhaps sooner than AGI”. What technology are you thinking of here?
Nvm, I found it: it was called the "Fifth Generation Project" but I cannot find that it was meant to lead to AGI through hardware improvements.
I seem to remember a project for a supercomputer in the 1970s or so. Its architects hoped its speed and memory would lead to AGI. I vaguely remember it being a Japanese project.
I cannot find this online. Does this ring a bell with anyone?

I noticed the yearly added distance doesn't decrease steadily, but jumps around a bit. Why is that?
You slightly misquoted it, which made it harder to find, but I found that passage.
I'd like to help you, but can you clarify what you're struggling with? Popper says right afterwards that if a theory doesn't predict more than the problem you're explaining, you get circularity.
@AijeCarvajal @ToKTeacher
Alternatively, read chapter 1 of "The Beginning of Infinity" by David Deutsch.
@AijeCarvajal @ToKTeacher
That was not blame. Do you not need to learn more philosophy? Do you already know everything about philosophy?
The source or format of an argument shouldn't matter, but if it has to be me, you could listen to soundcloud.com/dchacke/artifi….
@AijeCarvajal @ToKTeacher
I am familiar with the common sense conception of knowledge. It is wrong. You need to learn more philosophy in order to understand this.

Automatic or not, that is knowledge. It is encoded in genes. Knowledge does not require a knowing subject.

But that was not your question. I agree that capitalism couldn’t be phased out without coercion. Trying to end capitalism always ends in theft and violence.
Capitalism is what allows for creativity in the first place.
@ks445599 @SuUm4ya @HunterBergsma @RortyWitt
I made a mistake. I misread your tweet as saying “How do you phase out coercion and authoritarianism? Can’t be done”.
To which my answer is, yes, coercion and authoritarianism can be phased out and that would be pure creativity.
@ks445599 @SuUm4ya @HunterBergsma @RortyWitt
Sure it can. Such a state would be pure creativity.

Indeed. @woj_zaremba is actually talking about the prerequisites of being an effective universal constructor but doesn't realize it.
There are only two prerequisites for intelligence:
- Universal computation
- Creativity
More disappointments coming out of @OpenAI.
Only humans are intelligent, for only they have the universal ability to create new knowledge. And winning is only ever achieved through knowledge, not environments or tools. twitter.com/woj_zaremba/st…

@bnielson01 @Unendedquest @RatCritical @RealtimeAI @reasonisfun
Because lack of such a signal shows weakness. A weak man is less likely to be successful because he can be pushed around. A strong man is more stable and therefore a safer investment.
@Unendedquest @RatCritical @RealtimeAI @reasonisfun
This is not because women don't want to push buttons (twitter.com/reasonisfun/st…); they may decide to actively push buttons until the man signals that preparedness. Men generally do not require this sort of signaling from women.
@Unendedquest @RatCritical @RealtimeAI @reasonisfun
In relationships, it is typically women who expect men to signal the preparedness to leave anytime so they (women) feel safe investing emotionally in the relationship.
@Unendedquest @RatCritical @RealtimeAI @reasonisfun
Yes. Being prepared to leave isn't enough: things are only less likely to go wrong after one has signaled one's willingness to leave. Until then, an adversary may bet on one's not being prepared to leave and act accordingly.
@RealtimeAI @reasonisfun
That doesn't answer my question. I can see that it will make repeated violation of boundaries less likely. Those won't repeat if you walk away. But I don't see why it makes the first violation less likely.
Why does being prepared to leave make things going wrong less likely? You're still waiting for the first thing to go wrong to trigger your leaving, no?
