RT by @elonmusk: Unlimited tolerance is how open societies commit suicide. Elon Musk just warned that societies holding incompatible values eventually hit a reckoning. Karl Popper made the exact same point in 1945 while watching fascists and communists use open societies’ own tolerance against them. Popper wrote that unlimited tolerance must lead to the disappearance of tolerance. If a society keeps extending tolerance to people who openly want to destroy it and refuses to defend itself, the intolerant win and tolerance dies with them. He never demanded censorship first. Argue with intolerant ideas. Suppress them only when they stop arguing and start using force. 80 years later Musk is asking the same question: how much can a tolerant society tolerate before it stops being one?

RT by @elonmusk: Geoffrey Hinton says a big language model runs on about 1% of your brain's connections and still ends up knowing more than you: "So in your brain, you have a hundred trillion connections, roughly speaking. Okay. That's a lot. And you only live for about two billion seconds. That's not much." "If you compare how many seconds you live for, with how many connections you've got, you have a whole lot more connections than experiences." "Now with these neural nets, it's sort of the other way round. They only have of the order of a trillion connections. So like 1% of your connections, even in a big language model, many of them fewer, but they get thousands of times more experience than you." "So the big language models are solving the problem with not many connections, only a trillion. How do I make use of a huge amount of experience?" "And back propagation is really, really good at packing huge amounts of knowledge into not many connections." "But that's not the problem we're solving. We've got huge numbers of connections, not much experience. We need to sort of extract the most we can from each experience." Two to three billion seconds is the whole budget. Everything you know, you learned inside it. So evolution built you to squeeze a lot out of very little. Hinton's point is that a language model has the opposite problem and the opposite fix, and backprop turned out to be extremely good at that fix. Worth noticing what this predicts about failure. A system running on 1% of your wiring and thousands of times your experience is not going to fail the way you do. You fail from having seen too few examples. It fails from compressing too many into too little, and the compression is where the errors get made. That is a strange thing to be deploying into hospitals and courts with no way to inspect it. We test these systems by asking them questions, which tells you what came out. Nobody can yet look at a trillion connections and say what got packed in. - Geoffrey Hinton, Nobel laureate and Turing Award winner, on StarTalk (@StarTalkRadio) with Neil deGrasse Tyson.

RT by @elonmusk: Elon Musk on early days of SpaceX: "When I started SpaceX, one of my friends got a compilation of rocket failures & made me watch the whole thing. I knew the probability of SpaceX failing was high"

What has happened to towns who did nothing to deserve it, like little Piddington village, will happen to all of Britain, unless there is fundamental political change. It’s not right. Not right at all.

RT by @elonmusk: Grok is now available directly inside Google Workspace One add-on brings Grok into Google Sheets, Slides and Docs, where it works beside the file you already have open In Sheets, Grok can: • Read selected ranges and explain the data • Cite the exact cells behind its answers • Write and fill real spreadsheet formulas • Update values and rebuild financial scenarios In Slides, it can: • Generate a complete presentation from an outline • Add new slides that match the existing theme • Restructure entire sections • Rewrite titles so every slide communicates a clear takeaway In Docs, it can: • Draft directly inside the document • Turn rough notes into formatted sections • Correct grammar and rewrite content • Apply consistent headings and styles across the file Everything happens through a side panel, without constantly copying information between tabs or rebuilding the output manually One installation works across all three apps, and organizations can deploy it across their entire workforce Grok is rapidly becoming a native intelligence layer for the tools people already use every day

老石這篇說到點子上了 作為持豬肝護照的群體 從哪方面說都得支持高市早苗 小粉紅認為她讓日本經濟崩潰 那你們還不支持？ 反賊認為她是中共的剋星 那也必須支持💪 只有日本人才⋯⋯ 同理，持外國護照了，當然可以對「牆人劣根性」表示溫和包容，因為從護照顏色上說，那幫玩意再怎麼全世界散德行，也代表不了人家，與人家無關。但我們不行！

2026-07-25 07:09:53
這一點，大家真的不能學高市 很多人其實都活反了 越是人過中年才應該多睡 腦子裡一堆事 很多人睡不著是事實 所以能「按需睡眠」是福氣 跟吃飯的「少食多餐」一樣 有錢有閒每天都要多睡「幾次」 這比「保溫杯裡泡枸杞」養生 高市早苗身體堪憂 這是從她出來競選 我就一直在說的「短板」

There you have it, $GOOGL Waymo to explore split with $UBER per FT. My view last year was that Uber partnering with Waymo was a bad choice… since Uber would just serve as a distribution funnel that Google needed as they scale up. And that $NBIS Avride, other neutral players, or vertical integration would be the optimal path forward. Now their own partner Waymo looks to be the strongest disruptor to Uber.
