    Here's why I think there's now a one-in-six chance of an imminent global #NuclearWar, and why I appreciate @elonmusk and others urging de-escalation, which is IMHO in the national security interest of all nations: lesswrong.com/posts/Dod9AWz8…

    Dagan Shani has IMHO made the most important film of the year - about the harsh #AI truth:

    Help us find an unsung hero! If they win, they get $50k & you get up to $3k for nominating/spreading the word. Our first 3 awards went to Vasili #Arkhipov, Stanislav #Petrov & Matthew #Meselson, for helping prevent 2 #nuclear wars & 1 bioweapon arms race.

    Humanity's lackadaisical response to the superintelligence threat makes me feel I'm in the movie "Don't Look Up". I just explained why here:

    Our paper making neural networks more modular, sparse and interpretable by penalizing neuron length is now on arXiv. Less is more! @ZimingLiu11 arxiv.org/abs/2305.08746

    Most of my MIT colleagues are in denial of this coming tsunami
    Anthropic: Intellectual AI capabilities matching or exceeding that of Nobel Prize winners across most disciplines—including biology, computer science, mathematics, and engineering by 2026-2027 "Our own recent work adds further evidence to the idea that powerful AI will arrive

    Only about 18% of Americans voted for #realdonaldtrump yesterday – the biggest block chose not to vote at all! I just made this infographic:

    We just made the most scientifically complete #NuclearWar simulation to date, from fires to famine. As you can see, about 99% die in the US, Europe, Russia & China. Winner: nobody.
    How would a nuclear war between Russia and the U.S. affect you? Who would survive? Watch and share our most realistic nuclear war simulation yet:

    My beloved dad died peacefully this morning, after 92 inspiring orbits around the sun, retaining his dark humor and epic stoicism until the very end. I feel so grateful for all his love, wisdom and encouragement, and for getting to do 53 orbits together. ❤️

    No, LLM's aren't mere stochastic parrots: Llama-2 contains a detailed model of the world, quite literally! We even discover a "longitude neuron".
    Do language models have an internal world model? A sense of time? At multiple spatiotemporal scales? In a new paper with @tegmark we provide evidence that they do by finding a literal map of the world inside the activations of Llama-2!

    Like @EmmanuelMacron and @elonmusk, I don't want a world war – and I won't apologize for saying this. If you agree, please write #idontwantaworldwar as a reply to this tweet!
    What nuclear war looks like from space based on data from peer-reviewed science papers. A Nature Food paper today suggests that over 98% would starve to death in the US, Europe, China & Russia.

    Agreed: an unregulated race to the bottom will end badly for the human race.
    Dear everyone who wants to regulate and slow down AI: please stop fighting over who has the Most Correct Reason for the slow down. Just work together and make it happen! Reasons in alphabetical order: * autonomous weapons * bias * biosecurity * children's safety (more...)

    Our new AI paper reveals surprising geometric structure in the LLM-learned concepts: 1) They form brain-like "lobes", 2) they form "semantic crystals" much more precise than it first seems, and 3) the concept cloud is more fractal than round:
    1/6 New paper! “The Geometry of Concepts: Sparse Autoencoder Feature Structure.” We find that the concept universe of SAE features has interesting structure at three levels: 1) “atomic” small-scale, 2) “brain” intermediate-scale, and 3) “galaxy” large-scale!

    In an international climate treaty hopeless? No! 😃 That's how we mended the #OzoneHole, thanks to the heroes in this video, so we can succeed again with our future climate! #FutureOfLifeAward #Optimism
