"Today's AIs are book smart," reports the Wall Street Journal. "Everything they know they learned from available language, images and videos. To evolve further, they have to get street smart." And that requires "world models," which are "gaining momentum in frontier research and could allow technology to take on new roles in our lives." The key is enabling AI to learn from their environments and faithfully represent an abstract version of them in their "heads," the way humans and animals do. To do it, developers need to train AIs by using simulations of the world. Think of it like learning to drive by playing "Gran Turismo" or learning to fly from "Microsoft Flight Simulator." These world models include all the things required to plan, take actions and make predictions about the future, including physics and time... There's an almost unanimous belief among AI pioneers that world models are crucial to creating next-generation AI. And many say they will be critical to someday creating better-than-human "artificial general intelligence," or AGI. Stanford University professor and AI "godmother" Fei-Fei Li has raised $230 million to launch world-model startup World Labs... Google DeepMind researchers set out to create a system that could generate real-world simulations with an unprecedented level of fidelity. The result, Genie 3 — which is still in research preview and not publicly available — can generate photo-realistic, open-world virtual landscapes from nothing more than a text prompt. You can think of Genie 3 as a way to quickly generate what's essentially an open-world videogame that can be as faithful to the real world as you like. It's a virtual space in which a baby AI can endlessly play, make mistakes and learn what it needs to do to achieve its goals, just as a baby animal or human does in the real world. That experimentation process is called reinforcement learning. Genie 3 is part of a system that could help train the AI that someday pilots robots, self-driving cars and other "embodied" AIs, says project co-lead Jack Parker-Holder. And the environments could be filled with people and obstacles: An AI could learn how to interact with humans by observing them moving around in that virtual space, he adds. "It isn't clear whether all these bets will lead to the superintelligence that corporate leaders predict," the article concedes. "But in the short term, world models could make AIs better at tasks at which they currently falter, especially in spatial reasoning."

The BBC reports that a million-year-old human skull found in China suggests that the human species "began to emerge at least half a million years earlier than we thought, researchers are claiming in a new study." It also shows that we co-existed with other sister species, including Neanderthals, for much longer than we've come to believe, they say. The scientists claim their analysis "totally changes" our understanding of human evolution and, if correct, it would certainly rewrite a key early chapter in our history. But other experts in a field where disagreement over our emergence on the planet is rife, say that the new study's conclusions are plausible but far from certain. The discovery, published in the leading scientific journal Science, shocked the research team, which included scientists from a university in China and the UK's Natural History Museum. "From the very beginning, when we got the result, we thought it was unbelievable. How could that be so deep into the past?" said Prof Xijun Ni of Fudan University, who co-led the analysis. "But we tested it again and again to test all the models, use all the methods, and we are now confident about the result, and we're actually very excited."

Six months ago California had 48% more public and "shared" private EV chargers than gasoline nozzles. (In March California had 178,000 public and shared private EV chargers, versus about 120,000 gas nozzles.) Since then they've added 23,000 more public/shared charging ports — and announced this week that there's now 68% more EV charger ports than the number of gasoline nozzles statewide. "Thanks to the state's ever-expanding charger network, 94% of Californians live within 10 minutes of an EV charger," according to the announcement from the state's energy policy agency. And the California Energy Commission staff told CleanTechnica they expect more chargers in the future. "We are watching increased private investment by consortiums like IONNA and OEMs like Rivian, Ford, and others that are actively installing EV charging stations throughout the state." Clean Technica notes in 2019, the state had roughly 42,000 charging ports and now there are a little over 200,000. (And today there's about 800,000 home EV chargers.) This week California announced another milestone: that in 2024 nearly 23% of all the state's new truck sales — that's trucks, buses, and vans — were zero-emission vehicles. (The state subsidizes electric trucks — $200 million was requested on the program's first day.) Greenhouse gas emissions in California are down 20% since 2000 — even as the state's GDP increased 78% in that same time period all while becoming the world's fourth largest economy. The state also continues to set clean energy records. California was powered by two-thirds clean energy in 2023, the latest year for which data is available — the largest economy in the world to achieve this level of clean energy. The state has run on 100% clean electricity for some part of the day almost every day this year. "Last year, California ran on 100% clean electricity for the equivalent of 51 days," notes another announcement, which points out California has 15,763 MW of battery storage capacity — roughly a third of the amount projected to be needed by 2045.
