The scientist behind a landmark letter calling for a pause in developing powerful artificial intelligence systems have said tech executives did not halt their work because they are locked in a "race to the bottom". Despite support from more than 30,000 signatories, including Elon Musk and the Apple co-founder Steve Wozniak, the document failed to secure a hiatus in developing the most ambitious systems. Speaking to the Guardian six months on, Tegmark said he had not expected the letter to stop tech companies working towards AI models more powerful than GPT-4, the large language model that powers ChatGPT, because competition has become so intense. "I felt that privately a lot of corporate leaders I talked to wanted [a pause] but they were trapped in this race to the bottom against each other. So no company can pause alone," he said.

Fox News Flash top headlines for Sept. 14 are here. Check out what's clicking on Foxnews.com Famed Massachusetts Institute of Technology (MIT) computer scientist Richard Stallman is under fire after a leaked email thread showed him defending an associate of the late convicted sex offender Jeffrey Epstein, claiming that his alleged victims were "entirely willing." In the email thread, leaked by MIT alum Salam Jie Gano to VICE on Friday, Stallman argued that the late Marvin Minsky – an AI pioneer who died in 2016 and is accused of assaulting one of Epstein's victims, Virginia Giuffre, - had not actually assaulted anyone. "The word'assaulting' presumes that he applied force or violence, in some unspecified way, but the article itself says no such thing. Only that they had sex," he wrote, referring to an article about Giuffre's testimony against Minsky.

A prominent computer scientist and MIT professor believes there's a very good chance we're all living in a computer simulation. The idea of humans living in a simulated reality controlled by robotic overlords has been much explored by academics, experts and notable figures like tech mogul Elon Musk. But in MIT researcher Rizwan Virk's new book, 'The Simulation Hypothesis,' he probes the idea further, even examining how long it might take before humans could use today's technology to construct their own simulation of reality. MIT researcher Rizwan Virk believes it's more possible than not that we're living in a computer simulation akin to the scenario depicted in the 1990 sci-fi film the Matrix (pictured) There are several aspects of our world that explain why it's likely we are all living in a simulation, Virk said in an interview with Vox. He pointed to'quantum indeterminacy,' or'the idea that a particle is in one of multiple states and you don't know that unless you observe the particle,' Virk said.

In case you didn't make it to the ISCA (International Society for Computers and their Applications) session this year, you might be interested in a presentation by [Joel Emer] an MIT professor and scientist for NVIDIA. Along with another MIT professor and two PhD students ([Vivienne Sze], [Yu-Hsin Chen], and [Tien-Ju Yang]), [Emer's] presentation covers hardware architectures for deep neural networks. The presentation covers the background on deep neural networks and basic theory. Then it progresses to deep learning specifics. One interesting graph shows how neural networks are getting better at identifying objects in images every year and as of 2015 can do a better job than a human over a set of test images.

But automakers should be transparent with their data so independent researchers can assess whether certain self-driving cars are behaving in a biased fashion, Rahwan said. For example, if data shows a self-driving car is disproportionately harming specific people, like hitting cyclists over pedestrians, programmers should revisit their algorithms to see what's going wrong.

Joseph Weizenbaum, an MIT professor and a pioneer in artificial intelligence whose famed computer program Eliza seemed to converse with humans in 1964, spent the rest of his life speaking out against substituting machines for human decision-making. "He was a critic of society and science and a true humanist who really touched people," said Peter Haas, a Vienna-based filmmaker who made the 2007 documentary "Weizenbaum. Mr. Weizenbaum, whose parents fled Nazi Germany when he was a boy, died March 5 in Groben, Germany, from cancer. One of his four daughters, Sharon Weizenbaum, recalled playing with the Eliza program in her father's study at her childhood home in Concord. "Eliza was something that was fun to fool around with," she said.

Machine learning has proven it can beat traditional human techniques in healthcare for some time now, yet it remains limited in use in the healthcare industry. But that may be about to change. "Machine learning is changing everything -- except maybe healthcare," MIT professor John Guttag said here at the Big Data and Healthcare Analytics Forum on Oct. 24. While machine learning drives products and services such as Google Maps, many websites' tracking of shopping habits and presenting options, banking, credit card companies and others, healthcare providers have done much less with the existing technologies. "There's lots of talk, but very little action, very little progress in healthcare," Guttag said.

There are two main approaches to machine learning – supervised and unsupervised – and each has specific applications in the context of healthcare. And even though their impact has not yet sent shockwaves through the industry, the potential of each is enormous, according to John Guttag, head of the Data Driven Inference Group at MIT's Computer Science and Artificial Intelligence Laboratory. At its basic level, machine learning involves looking at data, and from that data finding information that is not readily visible. Example: Applying machine learning to data about patients infected with Zika or another virus and using what we can learn about what happens to those people to inform care decisions regarding the best ways to treat people who get infected in the future. "Typically we use machine learning to build inference tools, where we find patterns in existing data that allow us – when presented with new data – to infer something interesting about that data," said Guttag.

When John Guttag keynotes the HIMSS and Healthcare IT News Big Data and Healthcare Analytics Forum in Boston on October 24, the MIT professor will describe the unique challenges of applying machine learning to healthcare – as well as the huge potential for efficiencies and quality improvements as these data techniques become more widespread across the industry. Guttag, who heads the Data Driven Inference Group at the MIT's Computer Science and Artificial Intelligence Laboratory, and his MIT students are currently working closely with Mass General on integrating machine learning into clinical workflows, specifically with the aim of reducing healthcare-associated infections. "I want to actually see things change in the system, not just write papers saying things could change," Guttag said. "The goal here is to have something good happen. I hope a year from now I'm able to say, 'Guess what, we've lowered the rate of nosocomial infections at MGH – and more importantly put together a description of how we've done it that is exportable to other organizations.'"
