What computers can't do for you
We cannot explain to other humans the meaning of finite numbers either. How do you explain the meaning of "two"?

The Consciousness Question (If such a question really exists)
Is such a test needed? Isn't everything conscious?

1950's, 1960's children's Toys
I remember, I had it, too. Except it was called something else. Don't remember what, but it was in Cyrillic Metal parts looked exactly the same, but the architectural elements that look plastic here, were wooden pieces in my case. Even better look and feel that way. My mother was an architect and my father was a construction engineer - they made sure I got such stuff...

AI "hallucinations"
On the Origin of Hallucinations in Conversational Models: Is it the Datasets or the Models? (2204.07931.pdf (arxiv.org)) In knowledge-based conversational AI systems, "hallucinations" are responses which are factually invalid, fully or partially. It appears that AI does it a lot. This study investigated where these hallucinations come from. As it turns out, the big source is in the databases used to train these AI systems. On average, the responses, on which the systems are trained, contain about 20% factual information, while the rest is hallucinations (~65%), uncooperative (~5%), or uninformative (~10%). On top of this, it turns out that the systems themselves amplify hallucinations to about 70%, while reducing factual information to about 11%, increasing uncooperative responses to about 12%, and reducing uninformative ones to about 7%. They are getting really human-like, evidently...

OK, it might constitute a part of the solution. Like hair is a part of dog.

What computers can't do for you
I don't think that a substrate matters in principle, although it might matter for implementation. I think intelligence can be artificial. But I think that we are nowhere near it, and that current AI with its current machine learning engine does not bring us any closer to it.

Unless all these programs are already installed in the same computer.

Yes, this is a known concern.

I think I can program in random replication errors. Maybe I don't understand what you mean here

What computers can't do for you
(continuing my devil's advocate mission...) 1. The web, clouds, distributed computing, etc. are the environments of lots of cooperating computers, aren't they? 2. Hmm, I can't think of a good enough computer analogy of this... 3. Computers can self-replicate, at least in principle. (BTW, it took me some time to figure out what is paradoxical in your jigsaw example. But I did. I think, AI could deal with this kind of language vagueness, given enough examples.) (I gave the statement "My jigsaw has a missing piece" to Google translate and it has translated it correctly, without any inherent paradoxes, into both Russian and Hebrew.)

Is brain a computational machine?
Yes, I know, they started as somewhat different questions, but boiled down to the same subject. I'd like to hear your comparison, regardless where you post it. Perhaps the thread of what computers can't do, is more relevant. I took a note of the differences you've referred to before. Thank you. Perhaps, but what are these machines fundamentally missing that leads to this difference? What would prevent a sophisticated system of them to behave like a system described by iNow earlier:

Is brain a computational machine?
You explain, correctly, why the current artificial intelligence is human-like. However, my question is different: Is human intelligence computer-like? It specifically refers to the human intelligence abilities which are not realized in the current AI. The current AI realizes only very small subset of human intelligent tasks. What about the unrealized tasks? Are they or some of them unrealizable, in principle? Is there some fundamental limitation in computer abilities that prevents AI from mimicking all of human intelligence? Following the @studiot's clarification, let's stay with classical digital computers, because their functionality is precisely defined, via reducibility to TM. Anyway, all AI today is realized by this kind. Is human intelligence just a very complicated TM, or rather its functionality requires some fundamentally different phenomenon, irreducible to TM in principle? We know at least one such physical phenomenon, quantum entanglement. It is mathematically proven that this phenomenon cannot be mimicked by classical digital computers. Is human intelligence another one like that? If human intelligence in fact is reducible to TM, i.e. is realizable by classical digital computers, then perhaps intelligence of all other animals on Earth is so, too. But, if it is not, then another question will be, when and how evolution switched to this kind of intelligence? Mammals? Vertebrates? CNS? ...

Is brain a computational machine?
Yes, human because it is more interesting and understandable to us. OTOH, the goal is not necessarily pragmatic. It can be for sport or for research, for example. I don't think they developed artificial GO champion because it was needed.
-
Is brain a computational machine?
So, brains do many things that computers don't do, and computers do many things that brains don't do. Maybe the question should be narrowed to a domain where their functions seemingly overlap, namely, intelligence: Is human intelligence a biologically implemented computer?

Is brain a computational machine?
I think today "computation" applies to "whatever computers can do". This is certainly what they mean in the book I've cited in the OP.
-
Is brain a computational machine?
I didn't feel a need to mention Turing machines because any computation can be implemented by a TM. TM is a formally defined device useful for formal analyzing computations, e.g. compare their complexities. A computational machine doesn't have to be a TM, but whatever it does can be done by a TM. This includes AI neural nets of all types. Since they are implemented by computers, they can be implemented by a TM.

To add to this question: Does 'computation' include determining what to measure?

What computers can't do for you
DNN can approximate any function in a model, but the model is given to it. What I mean by coming up with a new model, in the astrology example for instance, is: would DNN come up with considering, instead of astrological data, parameters like education of a person, social background, family psychological profile, how much they travel, what do they do, how big is their town, is it rural or industrial, conservative or liberal, etc. etc. ?

Is brain a computational machine?
Materialistic/naturalistic perspective leads me to consider a brain to be some kind of machine. But, why computational? What do they mean when they say computational?

So there is no need for bigbang-theory?
For most galaxies, yes, it is so. For the very close galaxies, e.g. Andromeda, no. The redshift didn't change in the last 100 years.

Is brain a computational machine?
I've read today in a recent book on Artificial intelligence this statement: "a brain is a computational machine that happens to be made of neurons." (Stone, James. Artificial Intelligence Engines: A Tutorial Introduction to the Mathematics of Deep Learning (p. 183), 2020.) Is brain a "computational machine"? If so, in what sense?

Sufficient conditions for a critical point at (a, b, c)(i-e) [math]\nabla {f}(a,b,c)=0[/math]
x+y+z=10. You can express z by x and y. Then, you can substitute this expression for z in the given function, and it becomes a function of two variables. You can apply the theorem 2.6 as is to this function.

I don't know what "labeling data" is and how it relates to coming up with a new model. But will it come up with a new model?
