This week - Google's AI generates videos from text; neurons in lab play Pong; armed robodog dropped from a drone; and more!
We've had AI-generated images and now we have AI-generated videos. Google's Imagen Video can generate short 1280×768 videos at 24 frames just from a text prompt. Google is not releasing Imagen Video to the public, saying that the AI can be used "to generate fake, hateful, explicit or harmful content" and until these concerns are resolved, Imagen's model and code will be closed to the public.
In this talk, Andrew Ng compares the rise of AI to the rise of literacy. Like literacy hundreds of years ago, AI is accessible only to a highly trained group of people working for large institutions. Andrew Ng shares a vision for democratizing access to AI, empowering any business to make decisions that will increase their profit and productivity.
Nothing is true. Everything is permitted.
A video has been published on Weibo showing a drone dropping an armed robot dog on the ground.
Gillian Okimoto shares her experience of attending classes as a robot. She couldn't go to school and be with her friends once she was diagnosed with rare bone cancer. However, the hospital she was in had a telepresence robot and allowed Gilian to use it. So, for over a year, she was a robot. She also compares attending classes with a robot to remote learning and, in her own words, the robot "was light-years ahead of Zoom or Google Meet".
“Ai-Da”, described by its creator, Aiden Meller, as “the world’s first ultra-realistic robot artist”, appeared in front of the House of Lords communications and digital committee as part of its inquiry into the future of the creative industries in the UK. According to The Guardian, the meeting did not go smoothly. Ai-Da read typos from its pre-written script, struggled to hear questions, and needed to be rebooted halfway through the session.
Researchers have grown neurons in a lab and taught them to play Pong. Writing in the journal Neuron, Dr Brett Kagan, of the company Cortical Labs, claims to have created the first ''sentient'' lab-grown brain in a dish. Other experts describe the work as ''exciting'' but say calling the brain cells sentient is going too far.
Here is an interview with Sergiu Paşca - a researcher who grows little human brains to understand the causes of neurological and psychiatric diseases. He shares his journey into growing brains, how to transform skin cells into stem cells and then into neurons and how he uses them to study autism and other neurological diseases.
Some time ago, researchers successfully implanted human brain cells into rats' brains. Human cells were able to grow and integrate into rats' brains. A few months after they’d been implanted, the human cells made up around a sixth of the rats’ brains and appeared to have a role in controlling the animals’ behaviour. This invites the question: Are these animals still 100% rat?
