Heh, i saw a feynman video, immediate flytrap for my mind. and added bonus its you posting it. Thank you. Love your work. Have you looked into the impact of autocorrecting software for text, and how it may actually change the mind of the typist to better suit the corrector. If slow moving object suddenly is closer. Are you sure it was not like that maybe, a month ago. Or what was the median of language before auto correct? Is it better to choose a word suggested or spend more time manually typing your own "words" I think humanity is mistepping in this obscure observation. Auto corrected out of the correct voice that uniquely is you. And eventually the whole of all yous. We, or us if you like. I did not expect to be concerned about this. But I am.

I live in Bangladesh and because of the crappy education system here I'm stuck with studying business studies. I didn't have physics or chemistry in school level but I love physics and Feynman has been a big part of that. His lectures on physics have been a great respite from my pointless and ultimately futile existence. I left my job to study physics by myself and have gotten derailed. But every time I listen to this man talk, I am enamored to pick up a physics or a math book and bang my head against that wall as hard as I can. I hope someday I get to be a physicist of any caliber, even if it means I have to starve to death. Thank you, Mr Feynman, for being the light I wish to touch someday.

He just completely gets the idea that if he is going to communicate *anything* to anybody he is going to start from common ground: a common understanding of terms and their definitions, commitment to a shared objective (usually solving a problem or answering a question or teaching/learning something). So he asks questions.

He had no idea or experience of what intelligence is, but perhaps he does now; intelligence is to men (human beings) what flying is to bricks-they cannot experience it as-they-are; asleep-or just dreamers

[@klaxoncow]

Indeed, I've worked with AI and this is a point that I think escapes a lot of people. Intelligence, by its nature, is intrinsically flawed. Because to reason at higher and higher levels - which is a characteristic of intelligent thought - we're further and further abstracting away the fine details. Which is good on the one hand, of course, but it's also potentially bad. Because, as the saying reminds us, often "the Devil is in the details". Machines give perfect mathematical results. The more and more we make AI "human-like" in intelligence, the more mistakes it's going to make. And the crucial point is that this is intrinsic to what we're doing, not a failure of hardware or software. But an intrinsic failure of intelligence itself - to detect patterns, I must abstract. Through abstraction, I'm throwing away fine detail. But, you know: Chaos Theory. Fine detail is oftentimes crucial to accurate prediction and results. When the machine is asked to do maths, then it does so perfectly. But when the machine is asked to cast a value judgement over some patterns it's detected in inherently ambiguous language to predict the course of an inherently "fuzzy" real world out there... it'll start making mistakes. It will not be perfect anymore. As it's our great unique ability - and we love to flatter ourselves - humans often miss these subtleties of how our intelligence is a trade-off. "To err is to be human", as the saying goes. Well, I'd revise it to "to err is to be intelligent" and we must expect that the machines, in increasing their intelligence, will become... less trustworthy and reliable in their results. Don't get me wrong. Still incredibly valuable and to be pursued, and will be pursued to good and great effect. But just, you know, "manage your expectations".

[@relate]

@@klaxoncow I think he meant it as a joke about us recognizing computers showing intelligence by means of human laziness thanks to our design. Intelligence trying to use itself to scheme a more efficient or "lazy" way to do or not do something. Or as he put it, "If you want to create an intelligent machine you're going to get all kinds of crazy ways of avoiding labour." The weakness is our schemes to avoid work and its necessity is our relief. Side note, saying intelligence is intrinsically flawed seems like a gigantic philosophically arbitrary statement.

@@jgunther3398 Yeah, I said nothing like what you're trying to abstract it down to, and I never made any reference to anyone or anything being "dumb" or "smart" whatsoever. But I thank you for providing demonstrative proof of what I was saying. Your intelligence has abstracted what you think I said and, unfortunately, lost much of the crucial "fine detail" in actually comprehending what I was really saying. Which has lead you to error, in characterising my position with a strawman. And, no, that's not because you're "dumb", it's actually because you have intelligence. An ability to abstract, summarise, pull the wheat from the chaff, etc. I mean, in this case, I'd challenge you've actually done it incorrectly. But it is a characteristic of intelligence itself that you could do it at all. As AI becomes more human-like, expect it to start failing similar cognitive hurdles as well.

@SteppenWolff100 the interesting question though is why "most highscool and college students" dont see "finding hings out" as a pleasure. Are there really kids who are more curios than others? Maybe, but I'm sure almost everyone has something he is curios about. If, for example, you put one of the best artists at this time in front of the very same audience, would they listen to him with same interest as to Fenyman?

[@ziff_1]

There's actually a technique of explaining named after him ... "The Feynman Technique". The Feynman Technique is a method of learning or studying that was famously used by physicist Richard Feynman. Known for his ability to explain complex topics in simple, intuitive ways, Feynman created a method for learning that involves four basic steps: 1. **Choose a Concept**: Choose the concept or topic you want to understand and start studying it. Once you know what it is about, take a piece of paper and write the name of the concept at the top of the page. 2. **Teach it to a Child**: Write out an explanation of the concept on your page as if you were teaching it to a child. Not just any child, but a child who is old enough to understand basic terms and relationships, but is still a beginner in terms of the topic. Use simple language and avoid jargon. Make sure your explanation is so simple that even a child can understand it. 3. **Identify Gaps and Go Back to The Source Material**: When you pinpoint the areas where you struggle (where you forgot something important, weren't able to explain it, or simply have a shaky understanding), go back to the source material and re-learn it until you have a basic understanding. 4. **Review and Simplify (Optional)**: If you followed the first three steps and are able to explain the concept in simple terms, you’re done. If you want to be sure of your understanding, you can try to simplify your explanation even more or try to explain it to an actual child or a peer. The Feynman Technique exploits the fact that teaching is one of the most powerful ways to learn and solidify your understanding of a concept. By pretending to teach the concept to someone else, you can identify gaps in your understanding. And by simplifying the concept to the level of a child, you're forced to really understand the concept at a deeper level.

Isn't the human brain slowly built up through a person's lifetime in the same manner that a neural network is built via a machine learning model? I mean, like, isn't the whole of a human's experience basically logged and framed in our brains as what essentially is nothing more than some form of logic tree or SQL database or something to that effect?

His point about human intelligence at the beginning is excellent: Humans are not the most intelligent possible things, and there isn't much point in trying to imitate human intelligence, any more than there is a point to building a mechanical cheetah. You can think of things like the youtube algorithm as primitive intelligences with completely different senses than human have, which do things practically impossible for humans.

Pardon me if I think I can infer from your comment, that it's necessary to define "think", to define "intelligence", before making any comparisons. It was an observation I had, as soon as I saw the title of this video-"How can we say that something thinks, without defining first what thinking is?"

[@cowlinator]

Kurzweil doesn't talk about human emotion, just emotion. Many animals with brains, possibly all animals with brains, have emotion. Emotion might be a result of biological brain evolution, or it might be a fundamental component of any optimal solution for general intelligence.

[@bill8383]

@@theBaron0530 That was an interesting "thought".. How could you possibly define something that is 'first order' that literally defines the 'second order' problem space of linguistics for which you are referring to.. It's like the 'simulation' in totality trying to comprehensively define itself , when it lacks the means to 'look in', from outside itself >> because if it had the means to 'see' from outside then it would be "more than simulation" .. A system space, cannot define itself using only itself.. To think about thining, is a second order operation.. unless you have the ability to 'step outside' your thinking or have something else to reference off, than you cannot define 'thought'.. and if you did find somthing else to "reference off" (sorry about my shitty terminology) then that information is now a product of "your" thinking, therefore unable to define the totality of the system..

The problem he is referring to about heuristic #693 is present in today's reinforcement learning systems as well!

[@kekedong]

obviously not very much , it is only 30 years

[@kevinchoi9428]

Most pattern-matching algorithms today (Deep NN, for example) existed back in 1985 but was abandoned as ineffective because computing power at the time wasn't powerful enough. The rise of neural nets today is more of a resurgence than a new discovery.

in terms of procedures, no progress has been made, our progress has been only in terms of computing power, the 20th century gave birth to the smartest people in human history.

[@virajs]

Yeah I was about to say isn't heuristic weighting and selection, precisely what we call machine learning. So infact Feyman from the 50s has enough understanding of computer science to formulate and answer these questions with the same skill as we would today. The problem today, seems to me, is that we have become experts at using distracting jargon, and getting awestruck by big numbers.

[@sandipanumbc]

Also heuristic #693 reminded me of over-complete auto-encoders where the input simply gets copied to some of the hidden units in the hidden layer (when no noise is added to the inputs) and the autoencoder simply avoids to learn anything but the identity function

Poor Prof Feynman didnt know then that facial recognition AI Software would be a reallity 3 decades after this early 80s lecture. His greatest skill beyond exceptional scientists then & now, is that he was incredibly imaginative & a damn good communicator. If you have read his book on Quantum Electrodynamics (QED) with Feynman diagrams.... he made it so simple to understand even for average high school kid.

One thing that is wonderful and worth noting, in my view, is how often and how well he uses QUALIFIERS. Certain things are difficult but not impossible.

The mental beauty of Feynman is he can weave the irony into every step of his language display which makes it entertaining and at the same time genius that nobody else equates at the same time. What a wonderful human being he was. His NY accent helps in seemingly creating a stage for standup, which is in fact what he is doing here... an improvised standup routine.

[@nikolatasev4948]

A great video. It shows that when trying to get an intelligent answer/behavior from a machine, it is always critical to see how you present a real world and its problems to it. And, of course, given more resources machines will start exploiting all the loopholes you leave them.

[@phattjohnson]

The machine will never know the real world - the weakest link will always be the human operators who will always be feeding it biased, incomplete data... AI is a myth. Computer programs are getting better at what we would like them to do, but "AI" is just a buzzword.

Only because we provide near unlimited training data with captcha's and the like.

[@nektarsolne4niy804]

it wasn't considered "impossible". He said it himself - it just takes too long with the computational capacity and memory we have at a time. Human can do this faster. Therefore teaching a machine to do it would be impractical. And he later said the same thing about weather prediction (not much different from facial recognition conceptually) - right now machines are slow; but will probably get a lot faster and will be able to account for more parameters, as technology evolves. This is where we are now today. We have increased our capacity, and we have the algorithms. As a result we see a rise of AI in many fields.

This hits on so many important considerations in thinking about AI. 1. What do we mean by “AI”? I think the default being “better than all humans at everything” (AGI) but short of that, we need to be extremely clear about what the “AI” is “I” about 2. Corollary: any time something is good at one thing it’s trivially easy to come up with something it’s not good at 3. The problem of intelligence is thermodynamically bounded just like everything else-finite energy is available for computation. The whole “heuristic 693” anecdote is really remarkable in that the program is addressing its task by explicitly allocating energy. Such an insane depth of understanding of the subject expressed so accessibly. And t-shirt game strong too

Very interesting.

Therefore machine cannot fully discover valid abductive inferences due to the lack of intrinsic recontextualisation cognitive capacity.

I am still studying a lot. Some really good channel here in Portuguese idiom is very difficult but it is not impossible. There are, say, no more than reasonably good channels here. Maybe I could yield a kind of interview framework (only audio with slide show) channel casted with the bright English spoken scientists of the English spoken peoples of countries like it happens in the Event Horizon, I would guess. It is hard. Google translator doesn't solve many barriers, for instance, in math (yes, math is also spoken during lectures). Google also doesn't have equation search, say, using latex.

Feynman talked about our inability to build a definite procedure that can “recognize things”… Well that is precisely what the so-called deep learning versions of supervised learning do even better today than humans (i.e., more systematically). Machine learning transcended the whole idea of procedural programming. Nevertheless, it’s amusing how the “heuristics” he mentioned sound like weights in a neural network. Avoiding the collapse or the divergence of these weights became the challenge. Also, we can concur: AI shouldn’t be about writing poems but having a machine want to write a poem.
