Metaphysic’s new Live tool creates high-resolution photorealistic faceswaps and de-aging effects on top of actors’ performances live and in real-time without the need for further compositing or VFX work.
ChatGPT may be coming for our jobs. Here are the 10 roles that AI is most likely to replace
Media jobs across the board — including those in advertising, technical writing, journalism, and any role that involves content creation — may be affected by ChatGPT and similar forms of AI, Madgavkar said. That’s because AI is able to read, write, and understand text-based data well, she added.
“Analyzing and interpreting vast amounts of language based data and information is a skill that you’d expect generative AI technologies to ramp up on,” Madgavkar said.
Economist Paul Krugman said in a New York Times op-ed that ChatGPT may be able to do tasks like reporting and writing “more efficiently than humans.”
Will an AI Be the First to Discover Alien Life?
SETI, the search for extraterrestrial intelligence, is deploying machine-learning algorithms that filter out Earthly interference and spot signals humans might miss.
Our future could be full of undying, self-repairing robots. Here’s how
If we’re going to put an AI brain somewhere, it’s likely going to be a robot. The next step – making that robot immortal.
Google invests $300 million in Anthropic as race to compete with ChatGPT heats up
Check out all the on-demand sessions from the Intelligent Security Summit here.
According to new reporting from the Financial Times, Google has invested $300 million in one of the most buzzy OpenAI rivals, Anthropic, whose recently-debuted generative AI model Claude is considered competitive with ChatGPT.
According to the reporting, Google will take a stake of around 10% and Anthropic will be required to use the money to buy computing resources from Google Cloud. The new funding will value the San Francisco-based company at around $5 billion.

My name is Artem, I’m a computational neuroscience student and researcher. In this video we will see why individual neurons essentially function like deep convolutional neural networks, equipped with insane information processing capabilities as well as some of the physiological mechanisms, that account for such computational complexity.

Restaurants can’t find workers because they’ve found better jobs
Robots are coming. And since the workers are already leaving the industry, no one will be harmed and service will be cheaper. Loving it!
Nearly three years since the coronavirus pandemic upended the labor market, restaurants, bars, hotels and casinos remain perpetually short-staffed. But these workers didn’t disappear, they found better jobs.
Google CEO Sundar Pichai says users will be able to interact directly with AI features in its search engine ‘very soon’
He really wants to squash the competition.
AI “is the most profound technology” the company is working on, Pichai said. He first mentioned Google’s plans to become “AI-first” several years ago.
