I’m about to publish something on this, stay tuned. :)
@PopperPlay @ReachChristofer @DavidDeutschOxf
Yeah those with side effects transform minds, and, if they get a mind to act, the world.
The motivation for treating ideas as functions is to solve the problem of how to encode ideas in a computer program.
Ideas need not return the same output for same input, nor do functions.
@PopperPlay @ReachChristofer @DavidDeutschOxf
PS: The above is more of an answer to your question “Is there a way we can show that all possible conjecturing and problem solving descends from a single algorithm?” from popperplay.com/problem/Qb6ij0…
@PopperPlay @ReachChristofer @DavidDeutschOxf
So the explanatory universality of people is powered by the computational universality of functions. Those two universalities are deeply intertwined.
4/4
@PopperPlay @ReachChristofer @DavidDeutschOxf
Since Lambda Calculus is computationally universal, all ideas in the mind can be expressed as functions, and so the above is the same as saying that it’s a functional replicator in a mind that explores the space of all possible functions.
3/
@PopperPlay @ReachChristofer @DavidDeutschOxf
A more elaborate one: ideas replicate imperfectly within a creative mind and thereby inadvertently explore the space of all possible ideas. This is how sometimes ideas evolve in a mind that happen to solve a problem/explain something.
2/
@PopperPlay @ReachChristofer @DavidDeutschOxf
Some quick arguments for the explanatory universality of creative minds:
1) What couldn’t one guess? (nothing , it seems)
2) Humans are so far off the mark (we have built space shuttles age cured diseases etc) that it just makes sense to think they are universal.

@ReachChristofer @ks445599 @PopperPlay @DoqxaScott @DavidDeutschOxf
Yeah, IIRC, there is no computation a quantum computer can perform that a classical UTM couldn’t. It’s just that some of those computations run intractably slowly on UTMs compared to quantum computers.
@DoqxaScott @RealtimeAI @ReachChristofer
I once saw a video of a monkey swiping pictures on an iPhone. Cool, but not evidence of creativity.
@DoqxaScott @RealtimeAI @ReachChristofer
What do crows/monkeys/other animals do that couldn't be explained exclusively in terms of biologically evolved adaptations? Do you have a video showcasing such behavior, or maybe an article explaining it?
@DoqxaScott @ks445599 @RealtimeAI @ReachChristofer
I think conjectures are the result of imperfect replication of ideas in the mind.
@ks445599 @DoqxaScott @RealtimeAI @ReachChristofer
I'd leave out any considerations involving pattern matching because they are too close to empiricism. It's a mistake I have made in the past myself. Empiricism is tempting so it does sneak back into mind here and there if one isn't careful.
@DoqxaScott @RealtimeAI @ReachChristofer
I mean, maybe we can consider the result of any algorithm running in the mind a conjecture, but thinking of creativity as pattern matching is a dangerous path into empiricism, which is really creativity-denial.
@DoqxaScott @RealtimeAI @ReachChristofer
That's why I wrote "intelligence/consciousness" a number of times, because if you have one you automatically have the other.
@DoqxaScott @RealtimeAI @ReachChristofer
I didn't mean to suggest that intelligence and consciousness are the same thing.
I think intelligence = creativity. Same thing just different words. And I think consciousness, among other things, is epi-creative, meaning it arises from creativity.
@DoqxaScott @RealtimeAI @ReachChristofer
Ah - you’re saying the result of, say, a pattern matching algorithm is a conjecture?
@DoqxaScott @RealtimeAI @ReachChristofer
There may be value in it, idk, I’m just pointing out that one is an error and the other a result of one. They are different things. So I don’t think the comparison applies.
@DoqxaScott @RealtimeAI @ReachChristofer
Yes, with the proviso that no (or only little in the case of inborn ideas) knowledge of how to solve particular problems is given and needs to be evolved at runtime instead.
@DoqxaScott @RealtimeAI @ReachChristofer
Sounds like empiricism. Not sure what you’re trying to say. Please elaborate?
@DoqxaScott @RealtimeAI @ReachChristofer
Yes. Sometimes adaptations have enough reach to incorporate use of new tools etc.
Knowledge of any kind, no matter how sophisticated, is not evidence of intelligence.
@DoqxaScott @RealtimeAI @ReachChristofer
Well, a conjecture is the result of an erroneous replication in a mind, so I wouldn’t compare it to transcription errors per se.
But yes there are many differences between biological evolution and what I call functional evolution in a mind.
@DoqxaScott @RealtimeAI @ReachChristofer
Don’t see why those couldn’t have been genetically programmed?
@DoqxaScott @RealtimeAI @ReachChristofer
Not pedantic, good point. Errors in transcription do indeed happen somewhere in plant. But no evolution within plant. Hence not intelligent.
@DoqxaScott @RealtimeAI @ReachChristofer
I think conjectures and refutations are components of intelligence regardless of whether they are made consciously.
@DoqxaScott @RealtimeAI @ReachChristofer
There is no variation and selection happening within plants. They happen across plants.
And yes I think only people are intelligent.
@DoqxaScott @RealtimeAI @ReachChristofer
That's not creating knowledge. It's just updating some parameters and it all happens to genetically given instructions.
@DoqxaScott @RealtimeAI @ReachChristofer
Genes are within plants, sure, but they are not intelligent/conscious because new knowledge is not created from within them.
@ks445599 @RealtimeAI
It’s a way to avoid explaining that by saying that consciousness is somehow already present everywhere.
Similar to how Lamarckism, empiricism etc state knowledge is already present somehow.
2/2
@ks445599 @RealtimeAI
Agreee. Also note that panpsychism is not an explanation. It’s just a statement: everything is conscious to some degree. That’s too easy. Doesn’t explain what consciousness or at least what gives rise to it.
1/
@RealtimeAI @ReachChristofer
Both would only be intelligent/conscious if knowledge originated from within them.
3/3
@RealtimeAI @ReachChristofer
In the case of plants, the knowledge originated in biological evolution and the plant just inherited it through genes.
In the case of a Roomba, the knowledge originated in a the minds of programmers and the Roomba “inherited” it through programmatic instructions.
2/
@RealtimeAI @ReachChristofer
Cool :)
I don’t think a Roomba is intelligent/conscious. Both Roombas and plants contain knowledge, no doubt. But to determine whether they are intelligent, one needs to determine the origin of that knowledge.
1/
@RealtimeAI
Okay, so does a Roomba. Is a Roomba intelligent/conscious?
I haven't thought enough about whether children should be given more lenience than older people. I have a hunch that yes, they should, but I wasn't really commenting on that.
Whichever way one argues, the argument should invoke knowledge, or a lack thereof - not brains.
@RealtimeAI
Because they move? What about a speck of dust flying through the air?
Flawed, reductionist reasoning. All people, including children, are universal explainers. That their brains develop until 25 doesn’t change that.
Why are people so set on ignoring software?

Coercion isn’t just about physical force. It’s a psychological state in which one idea arbitrarily wins over a conflicting one without solving the conflict.
Yes - they're not creative because their pattern recognition algorithms were designed by biological evolution.
Creativity, OTOH, is evolution happening inside a mind, during the person's lifetime. People are not given pattern recognition algorithms genetically but create them.

Creativity is when you solve problems through conjecture and criticism.
The question should be the other way round: is pattern processing possible without creativity?
The answer: no, because one's creativity creates one's pattern processing algorithms.
@ChristopherCode @DavidDeutschOxf
Well, say you can memoize the original function - the person. Then you're not running it. You're just looking up results in a behavioristic table.
In "The Beginning of Infinity", @DavidDeutschOxf asks: "What is the difference between a computer simulation of a person (which must be a person, because of universality) and a recording of [it] (which cannot be a person)?"
An attempt at an answer:
Intelligence is creativity not pattern processing.
I'm told the page is slow right now but it does eventually come up.
Since AGI is powered by evolution happening in a mind, you cannot build AGI without understanding evolution. So I wrote a blog post about some common misconceptions concerning evolution:

@ashik_shanks @ReachChristofer @DavidDeutschOxf @ToKTeacher @dela3499 @reasonisfun
One theory is that both ideas are replicators in his mind that compete. It took a bunch of error correction for the new idea to replicate and outcompete the original one. Then it took some more for the original one to outcompete the new one.
@ReachChristofer @ashik_shanks @DavidDeutschOxf @ToKTeacher @dela3499 @reasonisfun
Yeah. And to say that knowledge != understanding is misleading. His explicit ideas did not match his implicit ones. He also explained the transition in terms of hardware (neuroplasticity). But his hardware didn’t change. His ideas changed.
@nchwd1 @Space_Station @Astro_Jessica @NASA_Astronauts @NASA
I was looking more for like, you know, an explanation in terms of physics... E.g. maybe the space shuttle in the foreground is too bright to see the stars in the background.
@Space_Station @Astro_Jessica @NASA_Astronauts @NASA
I sometimes wonder why the sky is pitch black in some photos taken in space and not others. Shouldn't stars be visible in this photo?
@RatCritical @ToKTeacher @reasonisfun
Don't think so. Consciousness seems to be epi-creative: you are aware of things when you look for errors with them and/or find errors with them.

The successful refutation of a bad explanation would need to include refutations of all its slight variants, which is intractable. Reject bad explanations out of hand instead. Create good explanations before you start testing.

But a nice list otherwise. Almost all of these are missing in narrow AI.
@bnielson01 @dela3499 @reasonisfun @davidmanheim @DavidDeutschOxf @_FitCrit
Maybe that gives it more of an evolutionary flavor? Idk. You could also use symbolic regression, which is "proper" GP.
Not much hinges on whether NNs resemble evolution because, as DD says, science is about explaining the world, not predicting/retrodicting data (curve fitting).
@twatschmitt @DavidDeutschOxf @reasonisfun @davidmanheim @_FitCrit @bnielson01 @dela3499
Or, a non-math example: why are my keys missing?
- I misplaced them.
- I misplaced them while wearing a hat.
- I misplaced them while wearing a green hat.
... and so on.
@twatschmitt @DavidDeutschOxf @reasonisfun @davidmanheim @_FitCrit @bnielson01 @dela3499
For example, points (0,0), (1,1) fit x, |x|, xn for any positive n, etc.
You can do this for any given points by simply finding one curve that fits them all and then arbitrarily varying it in the infinitely many sections that don't run through those points.
@dela3499 @reasonisfun @davidmanheim @DavidDeutschOxf @_FitCrit @bnielson01
Yeah, that's what I meant by minimizing cost functions. The parameters are updated, sure - but not varied in the evolutionary sense.
@reasonisfun @davidmanheim @DavidDeutschOxf @_FitCrit @bnielson01 @dela3499
Knowledge is created by guessing and criticizing solutions to problems, not “extrapolating” from data, or finding mechanisms to fit data ever better.
Machine learning is empiricism applied to AI research. Should be avoided if the goal is to build intelligent programs.
@dela3499 @reasonisfun @davidmanheim @DavidDeutschOxf @_FitCrit @bnielson01
From what I’ve seen, ML does not involve variation and selection. It’s about minimizing cost functions (how well does this fit the data?).

Not so much about correlation or IQ. Intelligence is the ability to create new knowledge to solve problems; consciousness, and with it suffering, seems to arise from that ability. Animals can't create new knowledge but only use genetically given knowledge. So they can't suffer.
@PrestonEmick @Aella_Girl
Creativity, the ability to create knowledge. Only people (by definition) have that.
No capacity for suffering without intelligence, so I voted intelligence.
It seems for that reason that preventative medicine and remedies should be sold at separate locations, no?
I meant that if you go to get your flu shot, someone else who is infected may previously have entered that building in search of flu remedy, making it more likely for you to get infected.
So going to get the flu shot may cause getting the flu (not in the sense anti-vaccers mean)
Is it me or should the place providing flu shots not sell flu remedy at the same time?
An explanation of the pattern you’re looking for so you can distinguish patterns from non-patterns.
A pattern recognition program is such an explanation.
Pattern recognition theories of mind are a dime a dozen. They are all false because you cannot decide what counts as a pattern without a theory first, so that theory cannot itself have come from an observed pattern.
I have no interest in continuing this conversation because you do not address my criticisms. No point in continuing.
The content of an explanation is a statement about what is out there in reality, how it works, and why.
Starting with observations leads to an infinite regress you fail to address. You seem to willingly ignore it, idk why.
You're displaying irrational discussion methodology by repeating your point over and over without addressing criticisms.
Again, they might well have an explanation of what the dog's nose looks like, yes. (That they wouldn't know what it would feel like seeing a dog's nose doesn't change this.)
It's not so much about thought. It's about knowledge: solutions to problems.
"Everyone knows that to do great work you need both natural ability and determination."
What do you mean by "natural ability"? Talent?
This isn't a productive way to think about knowledge, though. As I said, knowledge creation begins with problems, not observations.
A creative mind can - in principle, though extremely unlikely - happen to come up with a theory describing dog's noses without having ever seen them. What it would feel like seeing a dog's nose is a different matter (quale).
That's the right way to think about our role in the cosmos.

No. You're putting words in my mouth. I have already agreed that blind people would not know what red feels like. I have also explained that this concerns qualia, not knowledge generally. This is part of the root of your mistake: you keep mixing up qualia with knowledge.
You keep describing knowledge as if it was already present. It isn't. It needs to be created through conjecture. Such as how to observe the delta between blue and red.
Explanations in terms of neural structures/hardware not fruitful. Intelligence is software, not hardware.
