Societies have been “hacked”. We don’t know what was let loose in elections since 2012 & in particular around 2016 “events”. Matching in high dimensional space (lookalike audiences around god knows what is measured, latent or incidental) and it can’t even be reproduced.

Since we are seeing now more "validation" of narratives, using AI to pluck in holes in stories in particular of people that often are involved in lobbying, its worth upping this. We are roughly at that part. I need to improve the write-up to make it more accessible & abstract...

We have now the second sharp price signal in less than 5 years to build resilience in food systems. Circular economic solutions around biomass/agricultural waste, manure etc are ready to scale for many countries offering ample opportunities for domestic value chains to emerge.

Thanks for the feedback, I try to take this more on board as yes, maybe its a bit too much. But, one fun way to think about it as the bold text being annotations. Imagine we now strip the non bold text, could the document be reconstructed without this? This is effectively what (I think/perceive) the human brain does and is the type of corpus that LLMs are being trained on. So, I personally find it helpful to see what an author perceives to be important, it provides a window into the attention mechanism of the writer. Just like, say, an author organizes a book into chapters or sections. You seem to have a very strong emotional reaction to the visual encoding of information around this. When I have strong emotional reactions to "things", I try to reflect and ask myself: what is it that inside me caused me to have such a strong reaction? What are the assumptions or beliefs I hold about myself and/or about others that induce me to have such a strong reaction?

Interesting post, but I am the only one who gets annoyed at the abuse of bold text in writing? Not only is it stylistically horrible, but it insults your readers intelligence - I am capable of understanding the main points without you flagging them for me every 5 seconds!

Daron Acemoglu has used his language & authority to flag a serious risk: AI could contribute to a breakdown of knowledge transmission and a reduction in the stock of skills. I wanted to share some broader reflections on this topic on dimensions that I think are missing but not...

The two key determinants of workers’ lifetime losses (or gains!!) from accelerating a transition are thus their relative skill and remaining age. Since older folks vote at a higher rate than younger people, this is important politically.

Social scientists working with materials requiring digitization can only study what machines can read. In practice, that means printed Latin-script documents from well-funded archives. In a new working paper, I show that Vision Language Models used zero-shot outperform every existing OCR system across every script evaluated, and I propose a pipeline for deploying them on new collections. I apply it to six archival collections spanning 1.8 million pages across six countries for under $1,900.

Dear followers, I’m happy to share this new academic paper on how even capable AI can lead to deterioration of collective knowledge in society

I sure would hope so... informational boundaries anyone? In Germany, the previous government made sure the mechanical "means" for (more) targeted transfers has been put in place. In the UK, not really.

in many uses. And that explains much of what is going on in the geopolitics of it all and how climate action has become (partially) collateral damage. Answers are: technological convexification, demand reduction, circularity/recycling, and expansion of supply.

And here is the knowledge graph representation of the “why”: the I/O linkages of petroleum to downstream uses highlights propagation sharpness. But crude oil is increasingly substitutable in many applications — rare earths, while having a similar graph topology are Leontief…

A planning system that does not capture the land rents build low density communities that are a hard and costly to “run” absent WFH and spatial sorting — they act as a productivity tax on the commons and may be one of the many legacies of feudalism.
KingoftheCoast@kingofthecoastt

Why do cities w more stringent land use regs see similar house price growth in response to demand? Likely a fake composition effect. Their new homes are farther from the city center -- bc of regs. All else equal, far away homes have lower prices, to make up for costly commutes.

In Teilhard de Chardin's words -- I read his work as a teenager -- the noosphere is a stage in cosmic evolution where minds begin to interconnect & reflect collectively — ultimately moving toward what he called the Omega Point, a kind of convergence of consciousness. Open data...
