Geoffrey Hinton sobre la inteligencia artificial

 


Will Douglas Heaven entrevista en Technology Review del MIT a Geoffrey Hinton, sobre su actual desconfianza en la Inteligencia Artificial:

Hinton fears that these tools are capable of figuring out ways to manipulate or kill humans who aren’t prepared for the new technology.

“I have suddenly switched my views on whether these things are going to be more intelligent than us. I think they’re very close to it now and they will be much more intelligent than us in the future,” he says. “How do we survive that?”

He is especially worried that people could harness the tools he himself helped breathe life into to tilt the scales of some of the most consequential human experiences, especially elections and wars.

“Look, here’s one way it could all go wrong,” he says. “We know that a lot of the people who want to use these tools are bad actors like Putin or DeSantis. They want to use them for winning wars or manipulating electorates.”

Hinton believes that the next step for smart machines is the ability to create their own subgoals, interim steps required to carry out a task. What happens, he asks, when that ability is applied to something inherently immoral?

“Don’t think for a moment that Putin wouldn’t make hyper-intelligent robots with the goal of killing Ukrainians,” he says. “He wouldn’t hesitate. And if you want them to be good at it, you don’t want to micromanage them—you want them to figure out how to do it.”

There are already a handful of experimental projects, such as BabyAGI and AutoGPT, that hook chatbots up with other programs such as web browsers or word processors so that they can string together simple tasks. Tiny steps, for sure—but they signal the direction that some people want to take this tech. And even if a bad actor doesn’t seize the machines, there are other concerns about subgoals, Hinton says.

“Well, here’s a subgoal that almost always helps in biology: get more energy. So the first thing that could happen is these robots are going to say, ‘Let’s get more power. Let’s reroute all the electricity to my chips.’ Another great subgoal would be to make more copies of yourself. Does that sound good?”

Maybe not. But Yann LeCun, Meta’s chief AI scientist, agrees with the premise but does not share Hinton’s fears. “There is no question that machines will become smarter than humans—in all domains in which humans are smart—in the future,” says LeCun. “It’s a question of when and how, not a question of if.”

But he takes a totally different view on where things go from there. “I believe that intelligent machines will usher in a new renaissance for humanity, a new era of enlightenment,” says LeCun. “I completely disagree with the idea that machines will dominate humans simply because they are smarter, let alone destroy humans.”

“Even within the human species, the smartest among us are not the ones who are the most dominating,” says LeCun. “And the most dominating are definitely not the smartest. We have numerous examples of that in politics and business.”

Yoshua Bengio, who is a professor at the University of Montreal and scientific director of the Montreal Institute for Learning Algorithms, feels more agnostic. “I hear people who denigrate these fears, but I don’t see any solid argument that would convince me that there are no risks of the magnitude that Geoff thinks about,” he says. But fear is only useful if it kicks us into action, he says: “Excessive fear can be paralyzing, so we should try to keep the debates at a rational level.”


LeCun es muy optimista...si no fuera por los drones sobre Kiev, la prisión de Navalni, o las medidas de control social de China, quizá se podría aceptar su visión.

Publicando al IBM i sin IBM

 Un comercial de una empresa americana que trabaja con el as400, hoy llamado IBM i, cansado de escuchar afirmaciones de que el equipo ya no se fabrica ni usa, decidió publicar una empresa por vez,  que usa el equipo en Estados Unidos. Una idea que responde a la inactividad de IBM respecto a un equipo que le ha dado mucho dinero en los 35 años que lleva evolucionando, y que no se merece lo que en la práctica parece un ocultamiento de parte de IBM. Si usted busca información de desarrollo sobre el equipo, le costará encontrarla: si pregunta por DB2, será redirigido a DB2 para el system z, si pregunta por utilidades de SQL, o facilidades para procesar JSON, será redirigido primero al system z, y sólo refinando la búsqueda logrará acertar. Todos los enlaces preexistentes a artículos muy valiosos y bien escritos fueron perdidos y no redireccionados hace unos pocos años atrás. Los materiales existen, pero sólo una paciente búsqueda le permitirá llegar a ellos. Lamentable para un equipo que no ha dejado de evolucionar y adquirir funcionalidades de primera línea, cuya velocidad de procesamiento se mantiene muy competitiva, y que mantiene una gran base de clientes, que no recibe educación. En fin, quizá a fuerza de no educar y ocultar, IBM consiga que el equipo no exista. 

Lo que dice Alex Woodie sobre este esfuerzo solitario:

If you are a consumer of mainstream news, it can be hard to find anything about IBM i. The proprietary business platform isn’t marketed by IBM in advertisements and it receives very little coverage in mainstream IT publications. But a salesman for an IBM i business partner has come up with an easy yet compelling way to boost the visibility of the platform.

Earlier this month, Josh Bander, who is an enterprise account executive at Briteskies, shared a recent conversation he had through his LinkedIn page .“Over the weekend, I spoke to a few of my friends in IT, and they all told me #IBMi is dead,” Bander said. “To prove them wrong, I plan to take pictures of items in my house made with IBM i for the next week.”

The first picture featured Bander’s car, a Honda. The Japanese carmaker’s US subsidiary, American Honda Motor Company, has used one or more IBM i servers at its Torrance, California, facility for years.

Day three brought an image of a shoe by Nike. The legendary Oregon company has been an IBM i shop since at least 2003, when Nike acquired Converse, and it was still using IBM i in 2021, according to the list of IBM i shops maintained by All400s.com, which Bander used for his project.

A range hood for a stove made by Broan-NuTone appeared on day four of Bander’s IBM i journey through his home. The Hartford, Wisconsin-based manufacturer, which makes a variety of fans and air quality products, is also a confirmed IBM i ship.

Do you have Kleenex in your house? If so, then you have a product made by an IBM i shop, as the Irving, Texas-based Kimberly-Clark, maker of the Kleenex brand of facial tissues, is another confirmed IBM i user.

What about Taster’s Choice? It may not be everybody’s favorite cup of joe – Starbucks, the coffee goliath from Seattle, Washington, is a longtime IBM i shop – but the iconic coffee brand has IBM i in its veins, since it is owned by Switzerland-based Nestle, which is the largest food company in the world and another IBM midrange system user.

Maybe you have some shipping labels lying around. If they’re made by Avery Dennison, the well-known manufacturer of shipping labels and packaging materials based in Glendale, California, then you’ve found another everyday product made by an IBM i shop.

You don’t have to live the California wine country life to shop at Williams Sonoma. But if you do buy from the popular retailer, you can rest easy knowing that at least some aspect of the San Francisco company’s business is managed by IBM i.

Another iconic American brand, Rubbermaid, is also an IBM i shop. The Atlanta, Georgia company, which is now owned by Newell, was known to have run the IBM i as of 2021.

Bander’s LinkedIn posts of household items made by IBM i shops attracted quite a bit of attention from the IBM i ecosystem, and the hashtag “IBMiEverywhere” began trending. Apparently, IBM i professionals enjoy seeing that well-run and world-famous consumer brands are longtime IBM i users.

So why doesn’t IBM do this, or something similar? We have pestered Big Blue server execs many times over the years about the lack of marketing and advertising support for the platform, and rarely come away with satisfying answers.

To IBM’s credit, it does write and run case studies about IBM i customers. It has a section of its website where it has around 100 case studies of IBM i customers, as well as stories about a few business partners. Honda is on that list, as well as brands like Carhartt and Lamps Plus.

But there are many, many more name-brand companies that rely on IBM i that have never been officially mentioned by IBM as customers. Some of the world’s largest and most profitable companies run at least a small part of their businesses on the IBM i system, and while that in itself is not a reason for other companies to follow suit, it at least shows that world-class companies are continuing to invest in it and that has value.

IBM execs often say they wish they could do more to tout the great companies that rely on IBM i, and there’s no reason not to believe them. The truth is, the companies themselves often are not interested in participating in a formal IBM case study, marketing campaign, or to be featured in actual advertisements – and if they are, they often expect something in return for their cooperation.

That makes rogue efforts like Bander’s all the more fun and entertaining. John Rockwell does his best to keep the All400s list up to date, and while there are companies on the list that are actively moving off the platform or planning to, there are plenty more that are happy customers that aren’t going anywhere.

In the end, sharing unofficial lists of companies that run on IBM i seems to be a good way to boost morale for the IT soldiers in the trenches, who hear a lot of FUD and may be questioning their choice of platform. As it turns out, there are a lot of great companies that continue to rely on the box, which continues to run business software reliability, securely, and efficiently decade after decade.

They may not be shouting their IBM i success from the rooftops. But sometimes actions speak louder than words.

AI y la ética

 El mayor problema de la inteligencia artificial es que sus construcciones están basadas en principios matemáticos y lógicos, y estos no son suficientes y pueden ser desviados. Hace muy poco, Galáctica lo ha reflejado, en su inicio desastroso, capotando en tres días. GPT parece estar embarcado en mejorar esta aproximación, y es un proyecto en curso, arrasando todas las marcas de interés del pasado. Mientras tanto, las Big Tech probablemente deban realinearse. Dice Will Douglas Heaven en Technology Review:

While OpenAI was wrestling with GPT-3’s biases, the rest of the tech world was facing a high-profile reckoning over the failure to curb toxic tendencies in AI. It’s no secret that large language models can spew out false—even hateful—text, but researchers have found that fixing the problem is not on the to-do list of most Big Tech firms. When Timnit Gebru, co-director of Google’s AI ethics team, coauthored a paper that highlighted the potential harms associated with large language models (including high computing costs), it was not welcomed by senior managers inside the company. In December 2020, Gebru was pushed out of her job

El IBM i y sus capacidades actuales

 Dice Mike Pavlak: “At the end of the day, professionally I’ve worked in about six different languages. I can write bad code in every one of them,”

El contexto de la afirmación es interesante: el conjunto de recursos que hoy dispone el IBM i (¿o debemos decir IBM Power? ) para interconectarse con toda clase de recursos: PHP, Node, Python, sumados a los viejos conocidos de c. c++. java. Pavlak enfoca y evalúa la conveniencia de cada uno en función de conexiones con arquitecturas web, fundamentalmente, pero ese abanico de posibilidades puede ir más allá sin duda.

Dice Pavlak en particular sobre Node: 

Node.js isn’t as easy to learn for true-blue IBM i types, but it has one advantage over the other two: it uses JavaScript, which as previously noted has been broadly adopted by the wider IT world. However, there’s a caveat to the notion that Node.js developers only need to know JavaScript to be productive.

“A lot of people like Node because there’s a myth that I can use the same language on the presentation layer, JavaScript . . . up on the server,” Pavlak said. “And there’s truth to that. The syntax of the language is the same. What’s different though is the library usage. The libraries you’d use on the client end are not the libraries you would use on the server.”

Choosing Node.js makes sense in certain scenarios, such as when an IBM i shop has hired younger developers with JavaScript skills. Because the syntax is the same, these front-end JavaScript developers may be able to become productive developing back-end Node.js code on the IBM i server in a shorter amount of time than using other languages. “Using Node on the backend starts to make sense in that scenario,”

(...) Node.js does have a significant performance advantage over PHP and Python in on particular category: How quickly the stack starts. The technology, which was created by Google, is widely used by massive Web properties, such as Netflix. When you fire up a Netflix session on your TV, your Roku, or your phone, you’re actually initiating the deployment of a Node.js instance running on AWS.

“Node.js starts so fast, it’s so much easier to scale…horizontally,” Pavlak said. “So AWS instances are basically X86. In that scenario, Node has a decided advantage.”
