<p>Good point. It can't have much battery. Also wonder if the propellant/s are cryogenic. Monopropellant? You could tell from analyzing the plume.</p>

<p>Ok, so it actually flies. That was unexpected.<p>It's an incredible engineering achievement to build in massive fans and rocket engines into a high performance car. It's truly wild.<p>It's being sold in two modes. One with cold gas (no combustion) seemingly just for extra forwards acceleration (no flying) and one with real combustion rocket engines, the latter was in the video and is "invite only".<p>Wild that they devoted so much effort to an economically completely infeasible model. I wonder if the combustion version will even break 3 figures sales.<p>Even just the cold gas variant seems like a nightmare for production, there's a high pressure COPV in that thing and that's gonna make crashes much more.. exciting, and Tesla doesn't have a great record anyways. But very few of these are ever getting sold anyways.</p>

<p>I'm a Linux and Windows user thinking of getting a Macbook, mostly for the hardware.<p>All these recent proclamations of disappointment in Tahoe seem insanely overblown to me. The problem that this post leads with is that thumbnails' corners are too rounded, which "misrepresents" the original? Seriously?<p>Maybe it's worse now compared to the golden years, I don't know, never owned a Mac. And it's fair to criticize it from that perspective. But I am completely at a loss for how any of these issues could be bad enough to make you switch platforms. Windows and Linux are not exactly usability all-stars! I had to write my own app for decent speech-to-text on Linux which is built in at a system level on Macs.<p>This feels to me like just the age-old tale of people wanting to (love | hate) brands, when really, things are nuanced. I switched from Android to iOS recently and the experience did not change much. iOS is absolutely not "borderline unusable" like I've seen many claim. If anything it's maybe a 10% nicer experience overall.<p>Lack of nuance in people's takes makes for less signal in the noise and makes it annoying to figure out the actual pros and cons of different platforms.</p>

<p>It's an arms race between human writers and AI. Writers want to sound less like AI and AI wants to sound more like writers, so no indicator is reliable for long. Today typos indicate a real writer, so tomorrow LLMs will inject them where appropriate. Yesterday em dashes indicated LLM, so now LLMs use them less.<p>Beyond these surface level tells though, anyone who's read a lot of both AI-unassisted human writing as well as AI output should be able to pick up on the large amount of subtler cues that are present partly <i>because</i> they're harder to describe (so it's harder to RLHF LLMs in the human direction).<p>But even today when it's not too hard to sniff out AI writing, it's quite scary to me how bad many (most?) people's chatbot detection senses are, as indicated by this article. Thinking that human writing is LLM is a false positive which is bad but not catastrophic, but the opposite seems much worse. The long term social impact, being "post-truth", seems poised to be what people have been raving / warning about for years w.r.t other tech like the internet.<p>Today feels like the equivalent of WW1 for information warfare, society has been caught with its pants down by the speed of innovation.</p>

<p>Chinese builders are not equal to Chinese hackers (even if the hackers are state sponsored). I doubt most companies would be interested in developing hacking tools. Hackers use the best tools available at their disposal, Claude is better than Deepseek. Hacking-tuned LLMs seems like a thing that might pop up in the future, but it takes a lot of resources. Why bother if you can just tell Claude it's doing legitimate work?</p>

<p>That issue is the fourth most-reacted issue, and third most open issue. And the two things above it are feature requests. It seems like you should at the very least have someone pop in to say "working on it" if that's what you're doing, instead of letting it sit there for 4 months?</p>

<p>I'm thinking a lot about the ARC-AGI ML benchmarks, especially the "shape" of the dataset and what that says about how it should be solved. I think there's good reasons to believe that deep learning - at least differentiable SGD backprop style - is a bad fit for this specific benchmark, due to the tasks being almost entirely discrete symmetries, and also having so little data to approximate the discrete symmetries with continuous ones (considering deep learning to be the learning of continuous symmetries). I think that a more explicit and discrete approach is the way to go, and it's possible to build something surprisingly general and not heuristic-based even without gradient descent, guided by minimum description length to search for both grid representations and solver functions. I'm looking for teammates for ARC-3 so hit me up if this sounds interesting, I'd love to chat!<p>I made a viewer on my website to build intuition for my preferred perception algorithm which is entropy filtering + correlation. Pretty neat to check out the heatmaps for random tasks, there is a lot of information inherent in the heatmap about the structure of the task: <a href="https://synapsomorphy.com/arc/" rel="nofollow">https://synapsomorphy.com/arc/</a></p>

<p>Interesting essay. But it attributes something magical (ability to solve undefined problems) to humans and says that AI doesn't have it.<p>It seems pretty meaningless and not engaging with the real problem to say that AI doesn't "actually" write movie scripts or paint pictures. Like this doesn't line up with my definitions for doing those things which AI clearly fulfills.<p>And human intelligence arises from a well defined problem: maximizing f(environment, self) -> babies.<p>Also: if it were possible to measure, which it isn't, I strongly suspect that ability to solve well-defined problems and ability to solve poorly-defined problems are highly correlated, not totally uncorrelated. Happiness is a poorly defined problem, but it's just one of many, and has its own pile of things to consider that can isolate it from the general ability to solve poorly-defined problems.<p>I do like the framing. seems to be describing something similar to Goodhart's Law.</p>

<p>I'm completely puzzled on why space-based compute is so exciting to everyone all of a sudden. I have worked on spacecraft and the constant power benefit seems comically far from outweighing the many, many negatives, even if launch cost is zero, which we are still very far from.<p>Am I missing something? Feels like an extremely strong indicator that we're in some level of AI bubble because it just doesn't make any sense at all.</p>

<p>Not sarcasm at all.<p>There are some "AI thinkers" who are trying to make 8% faster CUDA kernels for attention, and there are some trying to save the world. These fields are called "capabilities" and "alignment". There is some overlap but not much.<p>LessWrong is mostly the latter, and labs and universities are mostly the former. That said, many LessWrongers work on AI at labs or universities or other places.</p>
