    Poincare missed special relativity because he knew too much: the leading physicists of the day were prisoners of their own expertise.

    Their wordshis expertise seems to be getting in the way. He knows so much, he understands so much, um and then he's not able to let go of these these things.

    What made the new astronomy compelling was neither accuracy nor simplicity but that one set of ideas explained three disconnected phenomena at once.

    Their wordsAnd so, you have what seem like three very different disconnected phenomena all being explained by this one set of ideas.

    The idea that Newton was the first modern scientist is wrong: he was a transitional hybrid, part superstitious and part modern.

    Their wordsAnd like, this idea that people have that that that Newton was um sort of the the first modern scientist is is somehow wrong. He I mean, it's there's some truth to it, but he really had this very different way um of of looking at the world that was part sort of superstitious um and part modern. It was a funny hybrid.

    Science always bottlenecks precisely where the heuristics that worked before stop applying, which is definitionally what makes something a bottleneck.

    Their wordsthe point is that where we always get bottlenecked is where the the previous processes and and and heuristics don't apply. Right? Like that's almost sort of definitionally what causes the bottlenecks.

    Darwin's genius was not having the idea of selection, which animal breeders already had, but seeing how central it was to the whole of biology.

    Their wordsand in some sense Darwin's genius wasn't in having that idea. It was understanding just how central it was uh to to to biology.

    Evolution was not a thinkable theory before deep time: without hundreds of millions of years it simply looks like a nonstarter.

    Their wordsif you don't have at least sort of tens or hundreds of millions of years, uh evolution just starts to look like a nonstarter.

    A trained model is a new kind of object that should be taken seriously as an explanation, once we work out the operations to perform on it.

    Their wordsAnd I think the like the third and the most interesting possibility is no, that like they're they're a new type of object in some in some sense. They should be taken very seriously as as explanations, but where in the past we haven't had the ability to really do anything with them.

    A theory gets abandoned when the old explanation becomes visibly insufficient: special relativity made Newtonian gravity's action at a distance impossible, and that was the forcing function.

    Their wordsUm and so, it's not a big leap to realize, "Oh, we have a big problem here." Um and so, you know, that's kind of the that's the forcing function there. It's it's you've realized that your old explanation is not sufficient. You need something new.

    Anomalies cannot be sorted in advance: the same move that found Neptune failed completely for Mercury, so a field has to pursue both answers at once.

    Their wordsAnd so you sort of you've you've pursued very similar ideas. It's been very successful in one case and it's been completely and utterly unsuccessful in the other case. And I think I mean a priori, you can't tell which of these is the thing to do. And you actually need to do both.

    AI has moved the programmer's bottleneck from writing code to having good design ideas, and there is no verification loop for a design idea.

    Their wordsSo certainly one thing that a lot of them seem to be bottlenecked on is now having interesting ideas and in particular having interesting design ideas.

    A theory of everything would not finish physics: Turing and Church laid down computation's theory of everything in the 1930s and we have spent ninety years exploring the consequences.

    Their wordsPeople will sometimes talk about um you know, a theory of everything as a potential goal for for physics. And and then there's this presumption somehow that physics is done once you get there. And of course, this is this is not true at all if you think about computer science.

    Comparative advantage stops governing once the power imbalance is large enough: groups then switch into seeking to dominate instead of trading.

    Their wordsand part of it is just power, I think. Like, once there's a sufficiently large power imbalance, um, very often, not always, but very often groups of people seem to to sort of shift into this other mode where they just seek to dominate.

    Most of the tech tree will never be explored by anyone at all, which is exactly why the choice of which direction to explore matters so much.

    Their wordsUm, there's just too many interesting ways of combining things. There's too many sort of deep ideas waiting to be uh, discovered and when it you know, not only we, but but nobody ever is going to to discover most of them. So, choices about how to make how to do the exploration actually matter quite a bit.

    Technological determinism is only believable low down the tech tree; higher up we already choose which paths not to take.

    Diminishing returns in research are not intrinsic to the world: they are what you get when the institutions around research stop changing.

    Their wordsIf you're not changing it, if there's some kind of stagnation there, if you're not changing those external sort of circumstances, yes, like you may start to get sort of diminishing returns again. But that doesn't mean there's anything intrinsic about the situation.

    Creative work splits into routine work you should get fast at and high-variance work you must be willing to spend a long time on, and almost everyone is good at only one of the two.

    Their wordsthere's sort of there's two types of work that tends to be involved in any kind of creative project. There's routine stuff and there you just want to avoid procrastination. You just want to like, you know, how do I get good at this or how do I outsource it and how do I do it as rapidly as possible? Um and just avoid you know, like getting into a situation where you're prolonging it. Um, and then there's high variance stuff where you actually you need to be willing to to you know take a lot of time.
