My conclusion, after reading the book, was that the author knows what test results you need in order to prevent or reverse cognitive decline, but he is no expert in how to get those results. Feel free to ignore whatever he says about how you optimize your test results, but I trust him a lot more on what happens when you have successfully optimized those results.
Doesn‘t every game end where it started?
Oh there is definitely a large group of people pushing this mistaken belief. When you hold the belief that there are no genders then logically there can be no women's sports and you cannot hold the idea that there are physical/mental differences between men or women without some for of cognitive dissonance.

The media and many others are backing transgender men entering multiple women's sports like it's not a problem. They're even ok with it happening in MMA and it's terrifying. You're going to have woman killed with this sort of stuff.

> describing spin-1/2 particles (i.e. generating SU(2))

This has the relationship backwards. Particles have this spin group because they can rotate in 3-dimensional space, not because they have some mysterious association with the complex plane.

That we can represent rotations using 2x2 unitary matrices of unit determinant is just a coincidence. There are a bunch of such coincidental isomorphism between groups. The explanation is comparable to the “strong law of small numbers” https://en.wikipedia.org/wiki/Strong_law_of_small_numbers

(The unitary matrices come about when we take points on the 2-sphere and stereographically project them onto the plane, representing points in the plane by complex numbers. Then concentric rotations of 3-space of correspond to particular Möbius transformations of the complex plane, which can be represented as the special unitary matrices. This works out cleanly when projecting onto a 2-dimensional plane, but representing rotations gets trickier in higher dimensions.)

* * *

But you are missing Jason’s point. There are clearly many possible ways of representing the same relationships. The underlying relationships don’t change if you e.g. use classical spherical trigonometry. The question he is trying to ask instead is: which representation is most conceptually clear and intuitive to work with (after some experience), has the nicest and easiest to manipulate notation, etc.

There are valid reasons to use a stereographic representation of points on the sphere. (For instance, it involves 2 coordinates instead of 3.) And from there, representing spherical rotations as Möbius transformations is convenient and effective. But conceptually, if trying to solve arbitrary problems with pen and paper, representing points as vectors and rotations as scalar+bivector "quaternions" is a lot more natural. Especially if you have a problem where some parts are not confined to the sphere.

For more on representing spherical geometry stereographically, cf. https://observablehq.com/@jrus/planisphere – there are some tools even here where we get leverage out of treating stereographically projected points as 2D vectors rather than as complex numbers, and separating the concepts of scalar, vector, and bivecor.

I agree with you that starling murmuration are chaotic systems in the mathematical sense. I don't think that this pop-sci article meant chaos in the mathematical sense though:

> “I’m interested in the transient moments when chaos briefly changes to order, and thousands of individual bodies appear to move as one,”

This quote in the article from the photographer makes it clear that she considered the birds to look/be chaotic before the brief moment when all the bodies moved as one.
In the spirit of recursion my own personal view is that the purpose of existence is to figure out the purpose of existence.

There are many questions we aren't really close to answering and our knowledge of this universe is very incomplete. Ultimately if we are able to develop a complete understanding of this universe down to the very origins of existence with no loose ends we can answer the question why we exist. So that's the goal. Help humanity answer this question. It might not be answered in your lifetime but the purpose of existence is not about your life. It's a longer term story that runs over countless generations eventually leading to the answer you ask.

The papers I provided go a bit beyond "electrical usage". One of them is cited by the paper in question.

Yes, they are approximations in lieu of more accurate data but that doesn't invalidate them as a tool or a motivation for future work such as this one.

Consider further that it's not just OpenAI's models in question: it's every practitioner who attempts to train similarly large models. These practitioners may not be using "green" data centers, even if we generously assume that OpenAI does. (Microsoft's 100% renewable target for data centers isn't until 2025. Read another way: they may be trying but they're not there yet.)

The available data and approximations illustrate that it is not accurate to assume that the average data center are powered by 100% renewables and carbon neutral. Thus the only reasonable conclusion is that more efficient models will have a positive impact on CO2 which is the motivation of the paper.

Even if you don't agree, it's not completely unfounded and is based on at least some research and data. At the end of the day, is this really worth fighting against? Who wants less energy efficient models?
Why is that not an issue with traditional crops? At least with GM crops if there is a known blight you can introduce traits that confer resistance to said blight in a much faster process than attempting to cross a high yielding and blight resistant strain and getting both favorable phenotypes in your crops. Especially with crops where it can take years for the progeny to reach maturity to even assess the phenotypes of the hybrids.

Until 2019 housing costs was one of the main drivers of inflation. The CPI had something like 3%-4% housing inflation but there are lots of products with barely any inflation which dragged the numbers to 2% or below.

The amount you pay on your mortgage and the amount that the previous homeowner gets are two different numbers because you have to pay interest on your mortgage. Low interest rates don't really change your monthly payment people the bank simply charges less interest which lets you bid for higher prices on homes. You get a more expensive home without paying more on your mortgage.

It's funny because if men didn't have clear advantage in sports (and competition in general as the advantage is there in less physical activities like mind sports/games as well) then it would be hard to justify existence of women only competitions. One of the conundrums of woke culture - no matter how you try to flex it your ideology doesn't fit the reality.

Btw, that anyone needs to see studies to be convinced men has significant advantage in sports over women is already a sad sign of common sense often being lost nowadays.
If you're lucky you might have a shot at changing the world, or at least having your name attached to something world changing that you – plus a whole bunch of others upon whose shoulders you stood – managed to ship. Some may argue that lucky is not the correct word here.

Away from that, on one dimension you then have the classic supporting-actor role. You baked the bread or brewed the beer that sustained the next Einstein or Estefan. Good job! On the same axis but a bit further removed: maybe you paid the taxes that paid Einstein2's research grant, or put Estefan2 through music school. Again, good job! Taxes are a good if slightly basic way of supporting your local society.

A different and orthogonal dimension is kids. You might directly raise Einstein3, or you might raise the guy who runs Einstein4's pub. At the very least your kids will be paying taxes to support the single mother of Estefan5. You can also support the people who raise kids. You're the solid gal who grows the potatoes eaten by the teachers who taught Estefan6 how to write.

You've got to play a part in society though. Some people withdraw from society and it's the most abysmal thing you could do as a member of a social, cultural, and technological species. I'm looking at you, preppers. Get back over here – back on the the grid as they would never say – and do something useful for the rest of us. Bake some bread! Think of the children!

I mean, I don't think there is non-free will either, but this debate is kind of confused because the widespread concept of philosophical free will, as "choosing one of a set of possible alternative futures to become real", is either self-contradictory or forces some very strange models of selfhood, to the extent of requiring some form of dualism or magical powers of consciousness. In contrast, I just think that people can evaluate imaginary futures and select which seems most pleasing, then act to bring it about, and that this is what free will is in the decisionmaking sense. But I don't think that's the same meaning of will as in this article, which seems to refer more to the ability to act from intention at all.

I think people instinctively feel that more extensive concepts of selfhood "aren't real" more because they don't have the conceptual tools to recognize and describe their presence in their minds. Most people behave as if self and control are real, at least.

For context, I believe that the universe fundamentally consists in a kind of mathematical structure; I don't think there is a reason to postulate a difference between "matter" and "the laws of physics" as a plain mathematical abstraction. As an extension of that, it seems to me that "models" of reality, such as self and the subjective perception of the universe, are embedded, compressed mathematical structures that can be viewed as a simplified abstraction plus an error term. We hold these models precisely because they predict and enable control of the larger system; this is occasionally useful. :) As such, I think they are fundamentally constructed, but not arbitrary - I think that's my major disagreement with the buddhist view.

Surely the ability to recycle/repurpose an old tyre matters more than the flats, so I'm not sure how this helps.

Also, I see the biggest concern as degradation of tyres contributing to rubber-dust pollution: "according to the UK government, and they are the second largest source of microplastic pollutant in oceans after single-use plastic"

Seems like it would be better to find an eco-friendly alternative to tyre rubber instead. If this design allows that (e.g. by allowing tyre materials that aren't as stretchy as an inflatable would need to be) I'm all for it, but that's a more complicated definition of "good for environment", dependant on other tech being developed.

Maybe a tiny minority do, but it isn't so much about the physicality and genes, but treatment and identification.

Hey, not taking sides here, just saying it's not as simple as reducing to people who think women and men (or female and male) are actually the same.

But if it helps taking sides, from our current way of doing most competitive sports, it makes sense to split into male and female (biologically speaking, at birth) and transgenders shouldn't compete on the other side.

When I first heard about premortems, the application was project planning. Before embarking on a project, you'd assume it failed and try to root cause the failures. You'd then take action to mitigate these risks (or possibly scrap the project completely if you discovered a fatal flaw, but that would presumably be rare).

I've since used them to mitigate risks to high-profile events that you can't really simulate, like major product releases or peak traffic events. In those cases, it's important that you do the premortem at a time where it can make a difference. Ideally there is a time when you are more or less code-complete but still have a few development cycles before the big day where you would be otherwise working on polish work.

Well, it's pretty easy to spot which information is not exactly right, what is unknown, and what is outright false.

It's not that difficult. Somehow the misinformation discussion gets derailed into "but what is actually the truth" empty debates, when the misinformation we are discussing is as stupidly false as "COVID is fake" or "vaccines don't work" for example.
I wonder if they could outsource this to the crowd. With things like Twitch, there are already lots of eyeballs on some of the higher-skill games. I mean you couldn't trust the twitch chat to actually do banning, but maybe they could flag things for in-house human review.

Independent of that and completely niche -- a game where they specifically themed it as some sort of 'gladiatorial combat,' and ranked the players based on crowd response could be cool. I definitely wouldn't want that in every game, but it could be a neat spin-off.

> What did the US even get out of it's relationship with China?

According to economic orthodoxy as old as Adam Smith, trading with a large trading partner makes both countries more prosperous.

It also reduces the odds of a shooting war. A shooting war between nuclear powers is likely to escalate to the point where it ends the world.

Also, the most important benefit of the current relationship with China is that warhawks can always grouse about it to distract the American public from domestic problems.
If I were to subject you to enormous pain you would cry out for it to stop. If I said "Why? Why does it matter if you're hurting? The universe is vast, you're a speck and you'll die soon enough anyway, as will we all" it would be entirely irrelevant. You'd still cry out for the pain to stop. It would still matter very much to you.

Just as "there's no point" is of no consolation in this situation, it should be of no detriment to your experience of happiness, beauty, love, fulfilment, etc.

People who decide that "there's no point" (for some usually ill-defined, abstract interpretation of that phrase), and conclude that this has some actual bearing on their lives, are deluded in a way that leads to nothing good. (I say this having been such a person.)

America stopped investing in itself because the ROI was much higher in countries with monumentally lower quality of living (and thus, lower worker wages and so on).
