I recently read Construction Physics' post on concrete use:

https://constructionphysics.substack.com/p/so-you-want-to-us...

and I consider it to be required reading for people outside of the field on the topic of concrete emissions. Globally, concrete production emits like crazy but this is largely a product of scale; other building materials emit far more GhGs by mass and volume but are used in much smaller quantities than concrete.

I'm all for a broad package of carbon taxes to both reduce growth and force the development of political and financial solutions for a low-growth, steady-state or degrowth economy but don't be misled into thinking the end result is a smaller share of concrete as a building material. More likely, carbon taxes will reduce the proportions of plastics, steel, aluminum and glass in construction in favour of more concrete.

Kotkin spoke to the Hoover Institute in Q1 this year about China and he had the insight that in any communist country you can't be half communist. It's a binary choice which means there's almost no opportunity for centrist constituencies to arise. The only constituencies are pro-central government, anti-central government and apathetic.

This makes government legitimacy the central political object that almost all political discourse revolves around, whether there happens to be a taboo in acknowledging it or not. Following this, policy mistakes become comparatively much harder to reverse in communist countries than in liberal/illiberal democracies, monarchies and pseudo-monarchies.

with Chinese characteristics.

I'd argue that PZ's idea of what globalization is is v. different to Morris Chang's idea of what it is.

Do you think a version tweaked for much greater incidence of "hallucination" would be a profitable sell to people who like cheap artistic text without being overly concerned about a human factor (eg: strapline writing) or too correlated with perceived low quality to sell well?

Is there an existing service where I can query an URL and get a list of preservation projects that have successfully archived that URL?

Wealth is unevenly distributed because the acquisition of wealth by agents is (and has been) unevenly distributed.

What property do all extant technologies possess (that some, yet undeveloped technologies, may not,) that has ensured that none of them have been able to flatten that distribution? Is it comprehensibility?

Was this article assembled by an AI from a bulleted list of story details? The structure is erratic and some paragraphs are repeated entirely.

Might work better if you use twitter frequently. I have less than 50 tweets and had three duplicate roasts in a sample size of ten.

Would expanded civilian nuclear power provide some kind of sustainable helium production as a side effect or do the numbers not work out?

Although it is a cliché at this point, a carbon tax would allow the market to efficiently balance these two concerns.

To paraphrase a joke from model theory, allowing facts to make claims about other facts up to recursion is a fine way to prevent any long-term success in natural language processing. If you drop absoluteness, the consequences will never be the same.

I'm not really familiar with math beyond linear algebra and googling was not very helpful; could you please give an example of an obviously incorrect result enabled by the axiom of choice? No need for detail, just the name of an example is good enough for me.
