I want to see more of that please! I want to see AI applied much more in science, technology, engineering, math, healthcare, altruistic usecases, etc. I want to see it as a tool that generates abundance for everyone. I want the technology to build better future for all. I want the technology to fight poverty and other world problems and risks. I want the research to help understand the nature of intelligence. I want the technology to empower all humans that don't want to see the world burn or are not dictators. I want the power of it be used for good. I want the power to not be concentrated. I want to see it developed safely and ethically in steerable way. I want people to get compensated properly. I'm trying to push that and help to work towards these goals more! I think in various industries AI is already technologically disruptive. AI is everywhere right now, and there's more and more of it, not just GenAI. Stuff like AI for foundational research and engineering in science+math supercharges all sorts of engineering+technology across the board. More and more programmers are using some sort of coding copilot, which is useful, and most of them are not using SotA systems like Claude, Cursor Sh, Perplexity, Replit etc. because of not knowing or because of the points above often. Or lots of code monkey stuff or unit testing or simple web dev, etc. is being automated. It's contributing to nontrivial frontier AI research and development. It's used to design better chips and robots. Or for example lots of translators and certain types of writers are rip. Then many companies squeeze for easy profit at all costs image/video/text gen for for example PR or in entertainment and art industry, but that is IMO often recently giving the technology bad reputation as it's often profit over quality and ethics, which sucks, and this technology can be used in much better ways there with more quality and ethics, but the incentives have to be aligned better. Automated call centers and customer service (sometimes better, sometimes worse quality). Autonomous vehicles are now reality, robot dogs, automated drones and other machines are already used in surveilence, defence, and wars right now, I don't want that, but some are using them for good and useful stuff too, like all sorts of specialized robotics for automation in resource and technology production and for household usecases is in it's glory, and humanoid robotics is just emerging. Planning systems are also big in defence and wars (I don't want that). Healthcare is supercharged with for example disease classification from images (I love AI for healthcare!). Financial market is ML bots fighting, recommender systems are everywhere in social media (often useful, but also often curse), semantic search is everywhere (often useful), visual recognition and editing of photos is used often (often useful), optimizations of supply chains, better techniques for agriculture (we need more there), automated thread detection in cybersecurity, optimizations in energy sector, AI powered scams etc. exist, and I wanna regulate that harmful usecase. This exists with a lot of dual use technologies. And I think that big factor limiting AI's impact inside industry, outside of academia, and outside of stuff like being superhuman in various games like Go, Chess, Dota, Poker, etc., are: 1) bureaucracy of integrating the technology is so slow compared to the progress of technology 2) People are learning to use the technology very slowly 3) issues around privacy, copyright, ethics in some contexts, and other legal issues 4) engineering around adapting the foundational systems for specific usecases is slower than the progress of the foundations systems ... AI can be used for both bad, good, and neutral things. Let's maximize the good usecases! #### Applications ([[AI engineering]]) - [[Artificial Intelligence#Crossovers|automating]] mundane tasks (dishes, laundry), [[Artificial intelligence x Healthcare|healthcare]] ([[AMIE]]), [[Artificial intelligence x Programming|programming]] (coding [[AI copilots]] such as GitHub copilot, [Cursor](https://www.cursor.com/), Replit, and [[autonomous software engineers]]), [[Artificial intelligence x Science|science]] ([[AlphaFold]]), physics ([[FermiNet]]), [[Artificial Intelligence x Mathematics|mathematics]] ([[AlphaProof]]), [[Artificial Intelligence x Engineering|technology]] development ([[AlphaChip]], [[virtual reality]]), [[chatbot]] assistants grounded in reality, [[education]], [[information searching]], minimizing various [[risks]] and [[crises]], [[transportation]], [[manufacturing]], [[security]], [[cybersecurity]], [[energy optimization]], [[supply chain optimization]], [[weather forecasting]], [[agriculture]], [[translation]], [[recommendations]], [[finance]], [[call centers]], [[entertainment]], [[legal services]], [[games]], [[robotics]] for good, etc. by [[prediction|predicting]], [[forecasting]], [[generation|generating]], [[classification]], [[analysis]], [[clustering]], [[segmentation|segmentating]] etc., with [[AI engineering]] methods using [[statistics|statistical]] models, [[deep learning]] models, [[generative AI]] models ([[Large language model|large language models]], image/sound/video models, [[multimodal]] models), [[classification]] models, [[reinforcement learning]] models, [[symbolic AI|expert systems]], etc. by [[building]] and [[training]] models, [[finetuning]], [[prompt engineering]], [[retrieval augmented generation]], [[agent]] and [[multiagent]] frameworks, etc. using [[PyTorch]], [[Keras]], [[Scikit-learn]], [[FastAI]], [[OpenAI]] or [[Anthropic]] API, [[Llama]] locally or deployed, [[Llamaindex]], [[Langchain]], [[Autogen]], [[LangGraph]], [[Vector database|vector databases]], etc. #### [[AI engineering]] by application - [[Generative AI]] - [[Large language model]] (LLM) - [[o1]] - [[Text-to-image models]] - [[Text-to-video models]] - [[Text-to-3D models]] - [[Music generation]] - [[Code generation]] - [[AlphaGo]] - [[AlphaZero]] #### More - By skill: - [\[2311.02462\] Levels of AGI: Operationalizing Progress on the Path to AGI](https://arxiv.org/abs/2311.02462)[[9bb2cfbcdbb8274393aa4b4fd2d4b604_MD5.jpeg|Open: Pasted image 20240115053147.png]] ![[9bb2cfbcdbb8274393aa4b4fd2d4b604_MD5.jpeg]] - [[Artificial narrow intelligence]] - [[Artificial General Intelligence]] - [[Superintelligence]] - [Outline of artificial intelligence - Wikipedia](https://en.wikipedia.org/wiki/Outline_of_artificial_intelligence) - <iframe src="https://en.wikipedia.org/wiki/Outline_of_artificial_intelligence" allow="fullscreen" allowfullscreen="" style="height:100%;width:100%;

Interpretability by Anthropic etc. is one of my favorite fields that I love to dig deep into! I was at a workshop by one of the founders of the field, I tried to replicate his paper, I played with some of the interpretability techniques in code. [An Extremely Opinionated Annotated List of My Favourite Mechanistic Interpretability Papers v2](https://www.alignmentforum.org/posts/NfFST5Mio7BCAQHPA/an-extremely-opinionated-annotated-list-of-my-favourite-1) [Mapping the Mind of a Large Language Model](https://www.anthropic.com/research/mapping-mind-language-model) [Chris Olah - Looking Inside Neural Networks with Mechanistic Interpretability Chris Olah 2023](https://www.youtube.com/watch?v=2Rdp9GvcYOE) [Open Problems in Mechanistic Interpretability: A Whirlwind Tour | Neel Nanda 2023](https://www.youtube.com/watch?v=EuQjiNrK77M) [I Am The Golden Gate Bridge & Why That's Important.](https://www.youtube.com/watch?v=QqrGt5GrGfw)) My current model of the biggest AI models currently is: Deep learning systems, each with their own architecture, are a weird messy ecosystem of learned emergent interconnected circuits. Various circuits memorize and others generalize, which is on a spectrum. An example of a circuit is an induction head. [In-context Learning and Induction Heads](https://transformer-circuits.pub/2022/in-context-learning-and-induction-heads/index.html) These circuits are in superpositions [Toy Models of Superposition 2022](https://transformer-circuits.pub/2022/toy_model/index.html) or/and in various ways localized and distributed. They are differently fuzzy and differently stable to random perturbations. They compose to various meta circuits like Indirect Object Identification. [Interpretability in the Wild: a Circuit for Indirect Object Identification in GPT-2 small](https://arxiv.org/abs/2211.00593) Initial layers of the AI model encode more low level feature detectors and later layers form more composed complex concept detectors. For example edge detectors, color detectors, curve detectors etc. compose into snout detectors, fur detectors and eventually into dog detectors. [Zoom In: An Introduction to Circuits 2020](https://distill.pub/2020/circuits/zoom-in/), [Curve Detectors 2020](https://distill.pub/2020/circuits/curve-detectors/), [Visualizing Weights 2021](https://distill.pub/2020/circuits/visualizing-weights/) On top of these layers you can do disentagling and decomposition of features and circuits using sparse autoencoders and other methods, which can be more fine grained or more coarse grained. This is done in mechanistic interpretability, which is a field that reverse engineers AI systems. And I see LLMs as semantic vector search engines with weak generalization capabilities. They have an internal ecosystem of vector representations of features and heuristics that you can retrieve by prompt queries. ([Francois Chollet's description](https://x.com/fchollet/status/1709242747293511939)) They are retrieving compressed knowledge and (sometimes less, sometimes more fuzzy) vector programs that are more concrete or abstract with weak generalization capabilities and (sometimes better, sometimes worse) composition. They can technically memorize compressed vector representations of various concrete and abstract programs (heuristics) and knowledge to some level of granuality with weak generalization. But they can also encode almost arbitrary generalizing circuits when we enhance our reverse engineering knowledge and techniques for steering the training and inference process. The new reinforcement learning chain of thought paradigm in OpenAI's o1 [Learning to Reason with LLMs](Learning to Reason with LLMs) is going more towards retrieving reasoning heuristics and composing them. [Is o1-preview reasoning?](https://www.youtube.com/watch?v=nO6sDk6vO0g) It's paradoxical how they can compose some features, but on others they fail utterly lol. They're specialized intelligences in different ways compared to in what ways humans are specialized intelligences. [General Intelligence: Define it, measure it, build it](https://www.youtube.com/watch?v=nL9jEy99Nh0) , [[o1]] , [Alice in Wonderland: Simple Tasks Showing Complete Reasoning Breakdown in State-Of-the-Art Large Language Models](https://x.com/JJitsev/status/1842727628463128968) You want a perfect sweet spot between memorization and generalization for optimal intelligence. This paper is also great: "We observe empirically the presence of four learning phases: comprehension, grokking, memorization, and confusion. We find representation learning to occur only in a "Goldilocks zone" (including comprehension and grokking) between memorization and confusion. We find on transformers the grokking phase stays closer to the memorization phase (compared to the comprehension phase), leading to delayed generalization. The Goldilocks phase is reminiscent of "intelligence from starvation" in Darwinian evolution, where resource limitations drive discovery of more efficient solutions."

There is less of this flexibility in symbolic AI and neurosymbolic AI, but that can be more efficient. But current mainstream AI systems are slowly morphing into neurosymoblic AI. Various math AIs like AlphaGeometry and AlphaProof uses LLM with symbolic Lean [AI achieves silver-medal standard solving International Mathematical Olympiad problems](https://deepmind.google/discover/blog/ai-solves-imo-problems-at-silver-medal-level/) o1 for reasoning uses CoT RL with reward model, not just pure deep learning [Introducing OpenAI o1-preview](https://openai.com/index/introducing-openai-o1-preview/) AlphaCode uses MCTS and sampling [Competitive programming with AlphaCode](https://deepmind.google/discover/blog/competitive-programming-with-alphacode/) AlphaFold for protein folding used graph network (with attention), which is one type of inductive bias, technically can be seen as neurosymbolic. [AlphaFold 3 predicts the structure and interactions of all of life’s molecules](https://blog.google/technology/ai/google-deepmind-isomorphic-alphafold-3-ai-model/) etc. The field of trying to understand the mind of AI is exploding! If the scaling hypothesis believers are right, as they have been to a certain degree so far, then [[superintelligence]] is coming soon. However, if they're wrong, all the hundreds of billions and potentially trillions of dollars invested could be viewed as one of the biggest bets that became one of the biggest wastes of resources in human history. [Can AI Scaling Continue Through 2030?](https://epochai.org/blog/can-ai-scaling-continue-through-2030) [X](https://x.com/EpochAIResearch/status/1826038729263219193), [$125B for Superintelligence? 3 Models Coming, Sutskever's Secret SSI, & Data Centers (in space)... - YouTube](https://youtu.be/QCcJtTBvSKk](https://youtu.be/QCcJtTBvSKk) Microsoft etc. wants to build 100 billion $ supercomputer for example. OpenAI [[o1]] showed new inference time scaling laws, so, we will see, how far will this go. In another 6 months we will possibly have o1 (full), Orion/GPT-5, Claude 3.5 Opus, Gemini 2 (maybe with Alphaproof and Alphacode integrated), Grok 3, possibly Llama 4 The capability of AI systems I'm the most interested in is if you gave the system all of classical mechanics, if it could derive general relativity and quantum mechanics from it, which seems to be a stronger out of distribution generalization than the current types of systems can do, but I'm open to be mistaken. And give it all (most of) known empirical data from experiments before the phase shift and derive it from these too. LLMs are such extremely fascinating systems relative to all the things they are capable of doing when they approximate the training data manifold by curve fitting with attention and interpolate on top of it with all sorts of vector program combinations. And it still boggles my mind how the models can sometimes generalize out of distribution a lot with just curve fitting by getting into generalizing short program circuit, that lies in often flat local minima, when they grok! Models are the data Memorization is the first step towards generalization Weight decay in deep learning incentivizes sparse generalizing circuits instead of inefficient distributed lookup table memorizing circuits Can all the missing capabilities and steering of AI systems be achieved in deep learning by incentivizing the emergent growth of them as grokked robust symbolic generalizing circuits encoded in matrix multiplications with nonlinearities? It would be great to have mathematical steering model that makes AI models trained on any arbitrary structured (mathematical) data grok that mathematical structure as a generalizing circuit Grokking in mechanistic interpretability of neural networks shows how learning symbolic algorithms using flexible nonsymbolic substrate comes as a sudden metastable phase shift into nonsymbolic's substrate's configuration of its parts mathematically corresponding to computing the symbolic algorithms The implementation details of all sorts of matrix operations black magic in code of low level deep learning engineering is just such a fascinating wizardry It's still weird that multiplicating and adding numbers together can compress information and generalize so well in deep learning How to formally define deception/lying to localize it in AI systems using mire formal mathematical analytical methods instead of statistical vibes? I tend to forget that so many tricks we use in deep learning in for example transformers are less than 10 years old, wtf Even tho LLMs can (for most tasks they're trained on) do just weak generalization by interpolation on the training data manifold, it's still so extremely useful in so many ways, like for math and coding, reformulating things, reexplaining things (for example using examples), knowledge retrieval, synthetizing knowledge, structure knowledge, synthetizing stories, combining concepts etc.! It's unbelievable how relatively good and useful in practice they are at so many of these tasks! Mechanistic interpretability is function deapproximation Here are additional extracted thoughts about AI mathematics, theory and engineering, continuing from most all-encompassing to most concrete: Bitter lesson: Is all we need hidden in trainable structure of training data? The model is the data, and if we feed it a ton of data from tons of modalities (not just human text, but also for example all sorts of synthetic data from physics simulations, etc.), might be possible to design data such that we get a lot of emergent generalizing technically superintelligent circuits If you overfit on the entire world, you are basically done. Machines are superhuman at many many dimensional manipulation and visualization We will create more and more predictive models about how deep learning works Black box AI models will be reverse engineered Reverse engineering AI systems is the most interesting and the most important thing Technical AI redteaming is machine learning whitehacking For some tasks we will need unconstrained creative open-ended alien intelligence to solve it, so we cannot fully steer all AI systems. Complete reverse engineering and formal verification might not even be possible, because the systems are evolutionary chaotic fuzzy statistical madness like organisms are to some extend, which will most likely be never fully interpretable and controllable, but only approximately, which is still useful, but only sometimes, but where we need it we should have it. Would mechanistic interpretability find out that Sora approximates wonky navier stokes equations for fluid dynamics? Would mechanistic interpretability find out that AlphaFold approximates current or better symbolic equations for protein folding? Hallucinations in LLMs are lowering with a lot of new research and engineering techniques, but probably it will be always effective to ground it externally realtime, unless the weights are somehow constantly updated and we reverse engineer the models in mechanistic interpretability and to good enough approximation figure out how exactly everything is stored and encoded in the weights of the model and manipulate the internals for perfect representations of facts and programs and do effective less faultty reasoning over them that minimizes hallucinations as much as possible to good enough level. You can tell when deep learning code was written by metamathemagician or empirical alchemist engineer Do you do frequent normalizations in your mental frameworks or do your gradients love to explode at slight perturbations? GELU activation function adds in some gel to prevent dead neurons that ReLU suffers from AI: Wins silver medal in international math olympiad, something that has been considered as an absolute AI win for a long time People, desensitized from the recent AI hype: Nothing ever happens Yawn AI gives unconstrained creativity "AI is just a fad" says while he uses tools that use machine learning algorithms everywhere he steps without even realizing it Inside of you are million dynamically on the fly constructed experts forming higher order experts I tend to forget that so many tricks we use in deep learning in for example transformers are less than 10 years old, wtf AI for the benefit of all sentient beings Growing robust neural circuits in my garden Stochastic parrots can fly so high We will steer superintelligence Fullbody strength training on caffine, creatine, protein, with Leopold's situational awareness of imminent superintelligence in first ear, Karpathy's GPT-2 from scratch in second ear, Stanford lectures on machine learning and transformers in third ear, Jeremy Howard's fastai practical deep learning for coders in fourth ear, Francois Chollet's algorithmic information theoretic model of general intelligence in fifth ear, Dive into Deep Learning in sixth ear, machine learning with pytorch and Sckit-learn in seventh ear, Deeplearning.AI's agentic LLM workflows in eighth ear, The AI Timeline, Latest AI Research Explained Simply in nineth ear, button down AI news in tenth ear, AI explained youtube channel in eleventh ear, bycloud AI news in twelveth ear, Wes Roth AI news in thirteenth ear, David Shapiro AI future in fourteenth ear, /r/singularity in fifteenth ear, /r/MachineLearning in sixteenth ear, /r/LocalLLaMA in seventeenth ear, Neel Nanda's reverse engineering of transformers in seventeenth ear, Arena mechanistic interpretability in eighteenth ear Grokking in reverse engineering of AI systems is the ultimate nerdsnipe Mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of mixture of agents made of...

Can't wait for other neurosymbolic approaches fundamentally embedded into the architecture or using LLMs in a composite system! Better interpretability of neurosymbolics will also make better steerability and generalization and therefore more novel thoughts! Mainstream LLM benchmarks suck and are full of contamination. AI explained has private noncontaminated reasoning benchmark. You can see how the models are actually getting better, and that were not really "stuck at GPT-4 level intelligence for over a year now". The implementation details of all sorts of matrix operations black magic in code of low level deep learning engineering is just such a fascinating wizardry One of my favorite ways of learning math with language models is prompting them to go step by step using examples through the various mathematical equations transforming data Memorizing the benchmarks is all you need AI systems need more centers from the brain implemented other than just language and visual centers Soon we'll be duplicating and merging layers in biological systems too and duplicating and merging biological and nonbiological systems together Autists (depth-first search) Schizos (breadth-first search) Autismophrenia, depth search of the breath of all possible topics in parallel Technically you can make LLMs learn new things by putting what you said into short term memory (context window, which disappears with a new chat when you use some wrapper over the raw model) or long term memory (into a (vector) database or "into neurons" by training, but that's not being really done in practice yet) the math of neural networks is 10000000 simplifications in a minute I find it cool that the form of that Xavier initialization is not empirical guessing, but actually there is some mathematical derivation behind it For deep learning systems mechanistic intepretability is a good approach in my opinion, because when we find featuras and circuits, we are able to do causal interventions, and thus steer the model The typology of features and cricuits has been explored a lot in CNNs before (1) and is now starting to be explored in transformers in language (2). We have only recently been able to decipher superposition more (3). 1: [Chris Olah - Looking Inside Neural Networks with Mechanistic Interpretability Chris Olah 2023](https://www.youtube.com/watch?v=2Rdp9GvcYOE), [Zoom In: An Introduction to Circuits 2020](https://distill.pub/2020/circuits/zoom-in/), [Curve Detectors 2020](https://distill.pub/2020/circuits/curve-detectors/), [Visualizing Weights 2021](https://distill.pub/2020/circuits/visualizing-weights/) 2: [Open Problems in Mechanistic Interpretability: A Whirlwind Tour | Neel Nanda 2023](https://www.youtube.com/watch?v=EuQjiNrK77M), [An Extremely Opinionated Annotated List of My Favourite Mechanistic Interpretability Papers v2 2024]([An Extremely Opinionated Annotated List of My Favourite Mechanistic Interpretability Papers v2 'Äî AI Alignment Forum](https://www.alignmentforum.org/posts/NfFST5Mio7BCAQHPA/an-extremely-opinionated-annotated-list-of-my-favourite-1)) 3: [Toy Models of Superposition 2022](https://transformer-circuits.pub/2022/toy_model/index.html), [Towards Monosemanticity: Decomposing Language Models With Dictionary Learning 2023](https://transformer-circuits.pub/2023/monosemantic-features/index.html), [Scaling Monosemanticity: Extracting Interpretable Features from Claude 3 Sonnet 2024](https://transformer-circuits.pub/2024/scaling-monosemanticity/index.html) I think you'll find out what youre looking for by whichever tools you're currently using. There are more specific and more general, simpler and more complex, etc., features and circuits depending on what kind of architecture and training data you have. You can find fur detectors in image models trained on animals. Finite state automata of HTML on code are found in models trained on code. Induction heads are more common and simple circuit in attention block in transformers across different training data. Indirect object recognition is a more complex circuit. E.g.

Similarly, I steered LLM through sparse autoencoder in Neel Nand's workshop. :D But the existing methods are still not sufficient, 100% efficient and interpeting everything. Architectures that will change through development and learning will change some features and circuits and not others depending on how generic they are and what stage of training you are in. They can reverse engineer realtime while training, so they can, for example, explore circuit formation phases and see different phase shifts, which is mega cool, for example with this paper I tried: [ Progress measures for grokking via mechanistic interpretability, reverse-engineering transformers learned on modular addition with learned emergent generalizing trigonometic functions circuit 2023](https://arxiv.org/abs/2301.05217) I'm all for trying to hardcode inductive biases (circuits) in AI systems, but it's also interesting to reverse engineer what features and circuits are emergently learned by deep learning, which can be many times more efficient, or impossible to hardcode by humans. Insights from reverse engineering deep learning systems can potentially be used to design new more intepretable and steerable architectures from scratch. Symbolic and neurosymbolic systems wouldn't need this reverse engineering so much because they would be more interpretable right out of the gate, but no one has successfully scaled them yet, so there is definitely some reason why black box (more white box over time as we reverse engineer them) deep learning is state of the art in so many tasks. The flexibility of deep learning is magical and absolutely necessary and useful for a lot of tasks, but in other tasks it can often be tragic if we don't reverse engineer it properly, and thus it can be less reliable, resillient, stable, steerable, etc. than we need, but that can be improved by reverse engineering and thus steering. There is less of this flexibility in symbolic AI and neurosymbolic AI. We get to sample the AI capabilities exponential just once a couple of years because it takes a while to build the supercomputers and train models on top of them Is AI overhyped in the short term and underestimated in the long term? I think the current AI boom might crash because of wayyy too early too big overly inflated expectations but then then AI will basically quickly boom again in a few years when new systems get released that are orders of magnitude scaled or algorithmically improved or with smarter data engineering or all or something else. A lot of the current inflated expectations will turn out to be true quickly soon in few years anyway, but so many of them are so early. And some exponentials are sampled too discretely. I think this will happen again and again. Booms and crashes will be closer and closer to eachother. Faster and faster, more compressed, closer to eachother overtime gartner hype cycles. A global exponential made of closer and closer local sigmoids. This is how I see the current technological singularity. Are we getting to the point where AI is too (under certain definitions of intelligence) intelligent for the regular folk so AI companies have to nerf it to increase its usage lol. LLMs are just the beginning of AI Will AGI be bayesian? Memorizing the benchmarks is all you need "Learn to use AI" is the new "Learn to code" ## Deep dives Now the biggest limitations in current AI systems are probably: to create more complex systematic coherent reasoning, planning, generalizing, search, agency (autonomy), memory, factual groundedness, online/continuous learning, software and hardware energetic and algoritmic efficiency, human-like ethical reasoning, or controllability, into AI systems, which they have relatively weak for more complex tasks, but we are making progress in this, either through composing LLMs in multiagent systems, scaling, higher quality data and training, poking around how they work inside and thus controlling them, through better mathematical models of how learning works and using these insights, or modified or overhauled architecture, etc.... or embodied robotics is also getting attention recently... and all top AGI labs are working/investing in these things to varying degrees.

I was a little surprised. | Science News](<https://www.youtube.com/watch?v=g7TghURVC6Y>), [Thousands of AI Authors on the Future of AI](https://arxiv.org/abs/2401.02843): "In the largest survey of its kind, 2,778 researchers who had published in top-tier artificial intelligence (AI) venues gave predictions on the pace of AI progress and the nature and impacts of advanced AI systems The aggregate forecasts give at least a 50% chance of AI systems achieving several milestones by 2028, including autonomously constructing a payment processing site from scratch, creating a song indistinguishable from a new song by a popular musician, and autonomously downloading and fine-tuning a large language model. If science continues undisrupted, the chance of unaided machines outperforming humans in every possible task was estimated at 10% by 2027, and 50% by 2047. The latter estimate is 13 years earlier than that reached in a similar survey we conducted only one year earlier [Grace et al., 2022]. However, the chance of all human occupations becoming fully automatable was forecast to reach 10% by 2037, and 50% as late as 2116 (compared to 2164 in the 2022 survey). Most respondents expressed substantial uncertainty about the long-term value of AI progress: While 68.3% thought good outcomes from superhuman AI are more likely than bad, of these net optimists 48% gave at least a 5% chance of extremely bad outcomes such as human extinction, and 59% of net pessimists gave 5% or more to extremely good outcomes. Between 38% and 51% of respondents gave at least a 10% chance to advanced AI leading to outcomes as bad as human extinction. More than half suggested that "substantial" or "extreme" concern is warranted about six different AI-related scenarios, including misinformation, authoritarian control, and inequality. There was disagreement about whether faster or slower AI progress would be better for the future of humanity. However, there was broad agreement that research aimed at minimizing potential risks from AI systems ought to be prioritized more."

[AI Index Report 2024 – Artificial Intelligence Index](https://aiindex.stanford.edu/report/) Top 10 Takeaways: 1. AI beats humans on some tasks, but not on all. AI has surpassed human performance on several benchmarks, including some in image classification, visual reasoning, and English understanding. Yet it trails behind on more complex tasks like competition-level mathematics, visual commonsense reasoning and planning. 2. Industry continues to dominate frontier AI research. In 2023, industry produced 51 notable machine learning models, while academia contributed only 15. There were also 21 notable models resulting from industry-academia collaborations in 2023, a new high. 3. Frontier models get way more expensive. According to AI Index estimates, the training costs of state-of-the-art AI models have reached unprecedented levels. For example, OpenAI’s GPT-4 used an estimated $78 million worth of compute to train, while Google’s Gemini Ultra cost $191 million for compute. 4. The United States leads China, the EU, and the U.K. as the leading source of top AI models. In 2023, 61 notable AI models originated from U.S.-based institutions, far outpacing the European Union’s 21 and China’s 15. 5. Robust and standardized evaluations for LLM responsibility are seriously lacking. New research from the AI Index reveals a significant lack of standardization in responsible AI reporting. Leading developers, including OpenAI, Google, and Anthropic, primarily test their models against different responsible AI benchmarks. This practice complicates efforts to systematically compare the risks and limitations of top AI models. 6. Generative AI investment skyrockets. Despite a decline in overall AI private investment last year, funding for generative AI surged, nearly octupling from 2022 to reach $25.2 billion. Major players in the generative AI space, including OpenAI, Anthropic, Hugging Face, and Inflection, reported substantial fundraising rounds. 7. The data is in: AI makes workers more productive and leads to higher quality work. In 2023, several studies assessed AI’s impact on labor, suggesting that AI enables workers to complete tasks more quickly and to improve the quality of their output. These studies also demonstrated AI’s potential to bridge the skill gap between low- and high-skilled workers. Still, other studies caution that using AI without proper oversight can lead to diminished performance. 8. Scientific progress accelerates even further, thanks to AI. In 2022, AI began to advance scientific discovery. 2023, however, saw the launch of even more significant science-related AI applications— from AlphaDev, which makes algorithmic sorting more efficient, to GNoME, which facilitates the process of materials discovery. 9. The number of AI regulations in the United States sharply increases. The number of AIrelated regulations in the U.S. has risen significantly in the past year and over the last five years. In 2023, there were 25 AI-related regulations, up from just one in 2016. Last year alone, the total number of AI-related regulations grew by 56.3%. 10. People across the globe are more cognizant of AI’s potential impact—and more nervous. A survey from Ipsos shows that, over the last year, the proportion of those who think AI will dramatically affect their lives in the next three to five years has increased from 60% to 66%. Moreover, 52% express nervousness toward AI products and services, marking a 13 percentage point rise from 2022. In America, Pew data suggests that 52% of Americans report feeling more concerned than excited about AI, rising from 37% in 2022. ## Written by AI (may include factually incorrect information) #### Map 1 # The Largest Comprehensive Map of Artificial Intelligence Paradigms Artificial Intelligence (AI) is a rapidly evolving field with a vast array of paradigms, methodologies, techniques, and applications.
