I used to think that today’s so-called “artificial intelligences” are actually pretty dumb. But I’ve recently changed my mind. In this video I want to explain why I think that they do understand some of what they do, if not very much. And since I was already freely speculating, I have added some thoughts about how the situation with AIs is going to develop.
It looks like AT&T experienced a data breach, leaving roughly 9 million customers data exposed. The data breach didn’t come directly from the wireless carrier, but occurred with one of its vendors.
The news originates from the AT&T forums, where customers were curious about an email that has apparently been going out to affected customers since last week. The email discusses the breach the wireless carrier experienced, sharing that it occurred with one of its vendor’s systems, which gave access to the wireless carrier’s “Customer Proprietary Network Information” (CPNI) system.
A series of three neuroimaging studies identified a pattern of neural activation involving specific brain regions that differentiates drug users from non-users with 82% accuracy. Researchers named the pattern the Neurobiological Craving Signature (NCS). Their findings have been published in Nature Neuroscience.
Craving is a strong desire to use drugs or eat. It has long been considered a key factor driving substance abuse and overeating. It is one of the criteria used for diagnosing substance use disorders. Craving is often induced by exposure to certain stimuli. In the case of overeating, these include the smell or sight of food. In the case of drugs, craving can be induced by one being in places or situations he/she associates with taking drugs or being offered drugs. This is called cue-induced craving.
Earlier studies of craving have successfully relied on self-reported craving, but recent research has focused on discovering its biological basis. Human neuroimaging studies have identified neural circuits related to the risk of substance abuse. Some brain circuits have been found to be involved in different substance use disorders and risky behaviors. These include specific parts of the ventromedial prefrontal cortex (vmPFC), ventral striatal/nucleus accumbens (VS/NAc) and insula regions of the brain. These regions also appear to play a role in weight gain and obesity.
While the world’s major powers are locked in an arms race to develop the best and most advanced hypersonic weapons, missiles capable of flying faster than Mach 5 and are thus able to defeat missile defense systems and radars, the Defense Advanced Research Projects Agency (DARPA) has been flying at these speeds for more than a decade.
The history of hypersonics go back much, much further than the 21st century. Nazi Germany’s V-2 rockets were able to reach speeds of Mach 4.3 after takeoff, but when they struck targets, they were often exceeding Mach 5. By 1949, the United States had adopted German rocket technology, which allowed rockets to exceed Mach 5 on takeoff for the first time.
Through this development, the U.S. was able to build its intercontinental ballistic missile arsenal, all of which were capable of speeds above Mach 5 upon reentry. It wasn’t until 1980 that hypersonic research began to focus on glide maneuvering and carrying people. This led to the creation of the X-15 rocket plane, a manned craft that could reach those speeds but was launched from a B-52 “mother ship.” An X-15 holds the official world record for the highest speed ever recorded by a crewed, powered aircraft when it reached Mach 6.7 in 1967.
Worker bees twerk in order to inform their coworkers of a pollen target. The specific communication signal that they use is referred to as the waggle dance. These bees perform steps to show where and how far the food is.
Now, a recent study has shed light on how bees actually learn how to do the waggle dance.
Altman, the 37-year-old CEO of OpenAI, invested $180 million in a startup that aims to delay death by 10 years, per the MIT Technology Review.
Australian researchers have uncovered an enzyme capable of transforming air into energy. The study, which was recently published in the prestigious journal Nature, shows that the enzyme utilizes small amounts of hydrogen in the air to generate an electrical current. This breakthrough paves the way for the development of devices that can literally generate energy from thin air.
The discovery was made by a team of scientists led by Dr. Rhys Grinter, Ashleigh Kropp, a Ph.D. student, and Professor Chris Greening from the Monash University Biomedicine Discovery Institute in Melbourne, Australia. The team produced and studied a hydrogen-consuming enzyme sourced from a bacterium commonly found in soil.
Recent work by the team has shown that many bacteria use hydrogen from the atmosphere as an energy source in nutrient-poor environments. “We’ve known for some time that bacteria can use the trace hydrogen in the air as a source of energy to help them grow and survive, including in Antarctic soils, volcanic craters, and the deep ocean,” Professor Greening said. “But we didn’t know how they did this, until now.”
ChatGPT might well be the most famous, and potentially valuable, algorithm of the moment, but the artificial intelligence techniques used by OpenAI to provide its smarts are neither unique nor secret. Competing projects and open-source clones may soon make ChatGPT-style bots available for anyone to copy and reuse.
Stability AI, a startup that has already developed and open-sourced advanced image-generation technology, is working on an open competitor to ChatGPT. “We are a few months from release,” says Emad Mostaque, Stability’s CEO. A number of competing startups, including Anthropic, Cohere, and AI21, are working on proprietary chatbots similar to OpenAI’s bot.
The impending flood of sophisticated chatbots will make the technology more abundant and visible to consumers, as well as more accessible to AI businesses, developers, and researchers. That could accelerate the rush to make money with AI tools that generate images, code, and text.
Andreas Braun, CTO of Microsoft Germany, announced the introduction of GPT-4 for next week. The models will be multimodal.
At the “AI in Focus – Digital Kickoff” event, Microsoft Germany presented business applications of large language models and talked about its cooperation with OpenAI and new Azure offerings resulting from it.
As Silke Hahn reports for Heise, Braun announced a GPT-4 reveal next week: “Next week we will present GPT-4, there we have multimodal models that offer completely different possibilities – for example videos,” Braun said.
