A lot of folks in the AI space are like people who insist it’s safe and smart to get drunk in the driver’s seat of their Tesla on a country road and a lot of their opponents are like people saying there’s no such thing as an automatic transmission

Grande sertao veredas
A hora da estrela
Dom casmurro
Vidas secas

These are some of the fiction classics. They might not reflect the current zeitgeist though. For that, there are some good new films/documentaries

This is the single best piece I've read on "replacing coders with AI," it fully dispells the myth from the perspective of a software engineer and does so in a calm, reasonable way.

There is a bunch I disagree with here, but it makes an argument for why AI adoption may be less rapid and less immediately world-changing (& dangerous) than people expect.

Well worth reading, as it is a useful base case where AI is just another technology. knightcolumbia.org/content/ai-a...

Why aren't university students more engaged? All they care about nowadays is "practical value" & making money, an attitude universities feed by increasingly mass-producing diplomas. [The American Mathematical Monthly 36(1), 1929]
"...be made with little study, and a position can be secured through channels other than that of scholastic attainment. The question uppermost in every student's mind is, "Of what practical value is this?" The information he seeks is that which he thinks will enable him to make ready money. But so long as the colleges and universities grant diplomas by the wholesale, why should we blame the student if he desires a diploma rather than the possession of that for which the diploma stands."

But DeepSeek shows - in the same moment as the Stargate announcement - that the trade off that OpenAI & co frame as wholly necessary is actually not. 15/

Quite the indictment of AI products: they are more appealing to people who don't understand how they work and see them as magical

The paper concludes: "businesses may benefit from targeting those with lower AI literacy" and "maintaining an aura of magic around AI" ✨

The whole special issue of the Journal of Continental Philosophy this article is part of is now online.

Really a great collection of the latest philosophical thinking on technology!

There are 2 mistakes you can make about LLMs:

① Thinking everything LLMs say is correct, they can reason, and with a bit more scale they’ll get us to superintelligence

② Thinking LLMs are good for almost nothing—they are FAR better at all #NLProc tasks than previous methods

Just realized BlueSky allows sharing valuable stuff cause it doesn't punish links. 🤩

Let's start with "What are embeddings" by @vickiboykis.com

The book is a great summary of embeddings, from history to modern approaches.

The best part: it's free.

Link: vickiboykis.com/what_are_emb...
Book outline Over the past decade, embeddings — numerical representations of
machine learning features used as input to deep learning models — have
become a foundational data structure in industrial machine learning
systems. TF-IDF, PCA, and one-hot encoding have always been key tools
in machine learning systems as ways to compress and make sense of
large amounts of textual data. However, traditional approaches were
limited in the amount of context they could reason about with increasing
amounts of data. As the volume, velocity, and variety of data captured
by modern applications has exploded, creating approaches specifically
tailored to scale has become increasingly important.
Google’s Word2Vec paper made an important step in moving from
simple statistical representations to semantic meaning of words. The
subsequent rise of the Transformer architecture and transfer learning, as
well as the latest surge in generative methods has enabled the growth
of embeddings as a foundational machine learning data structure. This
survey paper aims to provide a deep dive into what embeddings are,
their history, and usage patterns in industry. Cover image

How should we think about the value of human writing? What norms should we develop for labeling AI text? How can LLMs be built to better cite human writers' work and not plagiarize? How can we reduce their environmental impact? How can we mitigate biases?

As with every review cycle, this compelling argument about whether peer review accomplishes any of its stated goals. I don't think I agree with all of it but it's at least interesting
www.journals.uchicago.edu/doi/full/10....
 Prepublication peer review should be abolished. We consider the effects that such a change will have on the social structure of science, paying particular attention to the changed incentive structure and the likely effects on the behaviour of individual scientists. We evaluate these changes from the perspective of epistemic consequentialism. We find that where the effects of abolishing prepublication peer review can be evaluated with a reasonable level of confidence based on presently available evidence, they are either positive or neutral. We conclude that on present evidence abolishing peer review weakly dominates the status quo.

"92 million low-income people in the U.S. states—everyone whose income is less than 200 percent of the federal poverty line—have some basic aspect of their lives decided by AI"

www.techtonicjustice.org/reports/ines...

this is a damning report
reads: The Ways AI Decides How Low-Income People Work, Live, Learn, and Survive

The use of artificial intelligence, or AI, by governments, landlords, employers, and other powerful private interests restricts the opportunities of low-income people in every basic aspect of life: at home, at work, in school, at government offices, and within families. AI technologies derive from a lineage of automation and algorithms that have been in use for decades with established patterns of harm to low-income communities. As such, now is a critical moment to take stock and correct course before AI of any level of technical sophistication becomes entrenched as a legitimate way to make key decisions about the people society marginalizes.

Employing a broad definition of AI, this report represents the first known effort to comprehensively explain and quantify the reach of AI-based decision-making among low-income people in the United States. It establishes that essentially all 92 million low-income people in the U.S. states—everyone whose income is less than 200 percent of the federal poverty line—have some basic aspect of their lives decided by AI.
