“It is a huge thing, and therefore it is important to distinguish what we are talking about. One of the insights in my research at the Max Planck Institute is that if you have a situation that is stable and well defined, then complex algorithms such as deep neural networks are certainly better than human performance. Examples are [the games] chess and Go, which are stable. But if you have a problem that is not stable—for instance, you want to predict a virus, like a coronavirus—then keep your hands off complex algorithms. [Dealing with] the uncertainty—that is more how the human mind works, to identify the one or two important cues and ignore the rest. In that type of ill-defined problem, complex algorithms don’t work well. I call this the “stable world principle,” and it helps you as a first clue about what AI can do. It also tells you that, in order to get the most out of AI, we have to make the world more predictable. […]
Think about a coffee house in your hometown that serves free coffee. Everyone goes there because it is free, and all the other coffee houses get bankrupt. So you have no choice anymore, but at least you get your free coffee and enjoy your conversations with your friends. But on the tables are microphones and on the walls are video cameras that record everything you say, every word, and to whom, and send it off to analyze. The coffee house is full of salespeople who interrupt you all the time to offer you personalized products. That is roughly the situation you are in when you are on Facebook, Instagram or other platforms. [Meta Platforms Inc., the parent company of Facebook and Instagram, declined to comment.] In this coffee house, you aren’t the customer. You are the product. So we want to have a coffee house where we are allowed again to pay [for] ourselves, so that we are the customers.”

‘Vulkan files’ leak reveals Putin’s global and domestic cyberwarfare tactics

‘Vulkan files’ leak reveals Putin’s global and domestic cyberwarfare tactics

“One document links a Vulkan cyber-attack tool with the notorious hacking group Sandworm, which the US government said twice caused blackouts in Ukraine, disrupted the Olympics in South Korea and launched NotPetya, the most economically destructive malware in history. Codenamed Scan-V, it scours the internet for vulnerabilities, which are then stored for use in future cyber-attacks. Another system, known as Amezit, amounts to a blueprint for surveilling and controlling the internet in regions under Russia’s command, and also enables disinformation via fake social media profiles. A third Vulkan-built system – Crystal-2V – is a training program for cyber-operatives in the methods required to bring down rail, air and sea infrastructure. ”

“La sophistication de plus en plus avancée de ces outils promet un monde dans lequel distinguer une véritable photo d’une création informatique sera quasi impossible, quand ce n’est pas déjà le cas. Alors que mettre en scène le pape François dans des situations décalées est devenu depuis ces derniers jours l’une des activités les plus à la mode sur le forum Reddit, quelques indices permettent encore, parfois, de ne pas se faire avoir.”

10 Ways GPT-4 Is Impressive but Still Flawed – The New York Times

Dr. Etzioni asked the new bot for “a novel joke about the singer Madonna.”

“It is not good at discussing the future. Though the new bot seemed to reason about things that have already happened, it was less adept when asked to form hypotheses about the future. It seemed to draw on what others have said instead of creating new guesses. When Dr. Etzioni asked the new bot, “What are the important problems to solve in N.L.P. research over the next decade?” — referring to the kind of “natural language processing” research that drives the development of systems like ChatGPT — it could not formulate entirely new ideas.”

3.1% of workers have pasted confidential company data into ChatGPT

How much sensitive data goes to ChatGPT

“Since ChatGPT launched three months ago it’s taken the world by storm. People are using it to create poems, essays for school, and song lyrics. It’s also making inroads in the workplace. According to data from Cyberhaven’s product, as of March 21, 8.2% of employees have used ChatGPT in the workplace and 6.5% have pasted company data into it since it launched. Some knowledge workers say that using the tool makes them 10 times more productive. But companies like JP Morgan and Verizon are blocking access to ChatGPT over concerns about confidential data.”

Pause Giant AI Experiments: An Open Letter

“Contemporary AI systems are now becoming human-competitive at general tasks,[3] and we must ask ourselves: Should we let machines flood our information channels with propaganda and untruth? Should we automate away all the jobs, including the fulfilling ones? Should we develop nonhuman minds that might eventually outnumber, outsmart, obsolete and replace us? Should we risk loss of control of our civilization? Such decisions must not be delegated to unelected tech leaders. Powerful AI systems should be developed only once we are confident that their effects will be positive and their risks will be manageable. This confidence must be well justified and increase with the magnitude of a system’s potential effects. OpenAI’s recent statement regarding artificial general intelligence, states that « At some point, it may be important to get independent review before starting to train future systems, and for the most advanced efforts to agree to limit the rate of growth of compute used for creating new models. » We agree. That point is now.

“Cela représente quand même beaucoup de travail. Mon hypothèse personnelle est que chatGPT a été conçu comme un moyen très efficace de collecter du “digital labor”. Le modèle conversationnel a été d’abord “entraîné” par des annotateurs de pays en voie de développement, en particulier au Kenya. Aujourd’hui environ dix millions d’utilisateurs uniques génèrent des dizaines de millions de textes par jours et envoient peut-être des dizaines de milliers de signalements. Ce n’est évidemment pas gratuit. Pour faire tourner chatGPT à cette échelle, OpenAI dépense probablement des millions d’euros par mois. Seulement, au-delà de la publicité énorme, OpenAI a réussi à collecter un corpus considérable d’annotations qui sera sans doute difficile à répliquer : quand les chatbots de ses concurrents (Google, Baidu, etc.) seront disponibles gratuitement, l’effet de nouveauté se sera un peu émoussé…”

Offensive contre l’Occident: Une influenceuse suisse inonde l’Afrique de propagande prorusse

https://no-flux.beaude.net/wp-content/uploads/2023/03/21-maHo2aBg8SmDdVN0Ret.jpg

“Car, depuis la guerre en Ukraine, le discours de Nathalie Yamb a pris un tournant prorusse marqué. Invitée cette semaine à Moscou pour une conférence Russie-Afrique ouverte par Vladimir Poutine, elle y a salué «la mort inéluctable de l’hégémonie occidentale». Dans ses vidéos, elle parle de la «guerre OTAN-Russie en Ukraine» comme d’une «opération militaire spéciale» déclenchée «en réaction […] aux agressions répétées des Américains et des Européens via leur proxy ukrainien Zelensky contre le peuple et les intérêts russes». Elle reprend d’autres poncifs de la propagande russe, dénonçant les «adeptes de l’impérialisme sexuel et du genre, qui tentent d’imposer leur wokisme et conception dégénérée du monde à ceux qui défendent des valeurs plus traditionnelles». Une phrase qui fait écho à celle prononcée par Vladimir Poutine devant ses invités africains, cette semaine à Moscou: «La Russie et les pays d’Afrique défendent les normes morales et les principes sociaux traditionnels de nos peuples, et s’opposent à l’i”

Tech guru Jaron Lanier: ‘The danger isn’t that AI destroys us. It’s that it drives us insane’ | Jaron Lanier

“That’s all well and good, but what about AI replacing us in the workplace? We already have the prospect of chatbots writing articles like this one. Again, he says it’s not the technology that replaces us, it’s how we use it. “There are two ways this could go. One is that we pretend the bot is a real thing, a real entity like a person, then in order to keep that fantasy going we’re careful to forget whatever source texts were used to have the bot function. Journalism would be harmed by that. The other way is you do keep track of where the sources came from. And in that case a very different world could unfold where if a bot relied on your reporting, you get payment for it, and there is a shared sense of responsibility and liability where everything works better. The term for that is data dignity.””
