Here is a formal impossibility result for XAI: Informative Post-Hoc Explanations Only Exist for Simple Functions. I'll give an online presentation about this work next tuesday in @timvanerven.nl 's Theory of Interpretable AI Seminar:

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.

Today, building a fence with solar can be cheaper than using wood.

75% of gains in the S&P 500 centred on AI stocks are almost entirely driven by hype, and the hype has come unglued from reality.

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n
Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

Interesting work on science discussions on Bluesky vs. X. Bluesky post about science receives up to an order of magnitude (!) more interactions here: www.nature.com/articles/d41...
Research posts on Bluesky are more original — and get better engagement

It's seeming likelier and likelier that AI really could eliminate a lot of jobs very soon. Just not in the way boosters have suggested. www.theatlantic.com/economy/arch...
Just How Bad Would an AI Bubble Be? The entire U.S. economy is being propped up by the promise of productivity gains that seem very far from materializing. By Rogé Karma The capability-reliability gap might explain why generative AI has so far failed to deliver tangible results for businesses that use it. When researchers at MIT recently tracked the results of 300 publicly disclosed AI initiatives, they found that 95 percent of projects failed to deliver any boost to profits. A March report from McKinsey & Company found that 71 percent of companies reported using generative AI, and more than 80 percent of them reported that the technology had no “tangible impact” on earnings. In light of these trends, Gartner, a tech-consulting firm, recently declared that AI has entered the “trough of disillusionment” phase of technological development. By one estimate, Meta, Amazon, Microsoft, Google, and Tesla will by the end of this year have collectively spent $560 billion on AI-related capital expenditures since the beginning of 2024 and have brought in just $35 billion in AI-related revenue. OpenAI and Anthropic are bringing in lots of revenue and are growing fast, but they are still nowhere near profitable. Their valuations—roughly $300 billion and $183 billion, respectively, and rising—are many multiples higher than their current revenues. (OpenAI projects about $13 billion in revenues this year; Anthropic, $2 billion to $4 billion.) Investors are betting heavily on the prospect that all of this spending will soon generate record-breaking profits. If that belief collapses, however, investors might start to sell en masse, causing the market to experience a large and painful correction. The dot-com crash was bad, but it did not trigger a crisis. An AI-bubble crash could be different. AI-related investments have already surpassed the level that telecom hit at the peak of the dot-com boom as a share of the economy. In the first half of this year, business spending on AI added more to GDP growth than all consumer spending combined. Many experts believe that a major reason the U.S. economy has been able to weather tariffs and mass deportations without a recession is because all of this AI spending is acting, in the words of one economist, as a “massive private sector stimulus program.” An AI crash could lead broadly to less spending, fewer jobs, and slower growth, potentially dragging the economy into a recession. The economist Noah Smith argues that it could even lead to a financial crisis if the unregulated “private credit” loans funding much of the industry’s expansion all go bust at once.

Viktig inlaga av @erikangner.com i Svensk filosofi i debatten om universitetens frihet. För den som tycker att en fri akademi är värd att bevara är tiden att reagera på detta övertramp nu, inte "sen", för då tillåts denna förflyttning i auktoritär riktning.

A good summary expressing something similar to how I feel about the current hype around "AI". It just wish the hype would be over, that the grifters would turn their attention somewhere else, and that we all could move on to do purposeful "AI" again.
