Image by Michael Carroll in 2013. We did NOT see the little one coming; it hit Earth above Chelyabinsk in 2013, injuring >1400 people. Asteroid 2024 YR4 is bigger than the little one & perhaps as large as the football field! JWST 🔭 data next month will help pin down the size.

ALT Image by Michael Carroll illustrating the sizes of some asteroids in 2013. The asteroids are shown in comparison to a US football field. We had seen the big one "2012 DA14" coming, and it just buzzed Earth. But the littler one we did NOT see coming, and it hit Earth above Chelyabinsk, creating a shockwave the blew out windows and injuring more than 1400 people. The asteroid we are monitoring now - 2024 YR4 - is bigger than the little guy, but maybe as large as the whole football field! Our JWST measurements next month will help pin down the size of 2024 YR4. Source: https://carrollspaceart.com/gallery/comparisons/

The government’s new AI plan marks a big shift in direction.
Sunak saw the importance of AI but he tried to position the UK as the world’s AI safety leaders, emphasising the risks and in an eye-catching but negative way.

It feels almost pointless reposting this on X these days but, as we predicted, 2024 was the warmest in the instrumental record, and probably since humans evolved. The climate will not stabilise until we reach net zero, and that physics is not susceptible to lobbying or bullying
2024 has recorded the highest temperature in any year since 1850 🌡🌍
This is the 11th year in succession that has equalled or exceeded 1.0°C above the pre-industrial average period

Now that's one wild proposal ... scrap the #Artemis program immediately - and use the SLS built for Artemis II already to send a spacecraft after the first interstellar visitor we know. ;-) The LSST with the @VRubinObs should discover objects like this all the time, by the way.

@KevinRoose, of Hard Fork and NYT, was so impressed with OpenAI’s rollout that he joked “of course they have to announce AGI the day my vacation starts”.
For many people, what sealed the deal, or lead them to conclude, wrongly, that o3 necessarily “must be a step to AGI”, was o3’s performance on @fchollet’s ARC—AGI.
Yesterday war erupted over what was actually done. Here’s what you should know:
1.As NYU prof @LakeBrenden pointed out, the test should never have been called ARC-AGI. Even Chollet acknowledged this in his blog, saying “it’s not an acid test for AGI”. At *most* the test is necessary for AGI; it certainly isn’t sufficient. Critical things like factuality, compositionality, and common sense aren’t even addressed.
2.The video should have been much clearer about what was actually tested and what was actually trained. To the average listener it may have sounded like the AI took the test cold, with a few sample items, like a human would, but that’s not actually what happened.
3.What was actually done - pretraining on what I believe was hundreds of public examples - is NOT comparable to what humans require. Such pretraining is not uncommon in the field, but was not made clear in the video. Altman saying that the test wasn’t “targeted” added to the confusion.
4.Because of the pretraining, and lack of comparability, what was actually shown was disappointing. @Thom_Wolf, cofounder of HuggingFace, wrote “people commenting that it's normal to train on the train set but somehow I would have expected/hoped that as we're nearing AGI-level capabilities we would not need to really fine-tune/specifically train the model on any specific downstream task”
5.Two graphs, one presented by OpenAI and one by Chollet were misleading. As the DeepMind’s @olcan pointed out, the Chollet blog version made the breakthrough seem bigger than it really was by omitting results from others like the @jacobandreas lab at MIT. Same was true of the openAI graph: the MIT work (halfway in between o1 and o3) and many others results weren’t shown, making the breakthrough relative to the field seem far bigger than it really was.
6.As the scientist @AdanBecerraPhD put it (and Chollet publicly agreed) the best thing would have been to present data for the “base model” without the pretraining. This is what many people thought they saw, and that # is important scientifically. Unfortunately the key test was not done.
7.The way in which influencers tried to frame my legitimate criticism as being exclusively about my personal alleged bias was intellectually dishonest. Many others, including researchers from HuggingFace, DeepMind, NYU, and Huawei, and even Chollet himself, shared many of my concerns. Every single point I made was shared by at least one other researcher with a PhD.
Conclusions
⁃The problem wasn’t the task per se (a fine addition to our benchmark collection), or even how it was administered (legit relative to the test’s rules), it’s in the impression that OpenAI conveyed, which left many (not all) people believing that more had been shown than actually was.
⁃We still don’t have a solid test of what o3 does without the pretraining, in the case that would be more comparable to humans
- Because the wrong experiment was performed, and key data weren’t given, we can’t compare directly with humans. (And best humans still outperformed the model).
⁃Until there is considerable external scientific scrutiny (so far there has been none), we won’t really know exactly what the o3 advance is or how important it is.
⁃What we saw is not AGI. Both Chollet and OpenAI’s @anupk24 made this clear, but only after the video.
⁃People in the media probably shouldn’t even joke about it being AGI. The media should be asking hard questions, not fanning hype.
