CAIL = prerequisite knowledge for a critical perspective, such as to tell apart nonsense hype from true theoretical computer scientific claims. For example, the idea that human-like systems are a sensible or possible goal is the result of circular reasoning and anthropomorphism. olivia.science/ai

Si nos importa hacer campaña/tener conversaciones efectivas, en vez de hacernos señalamiento virtuoso entre nosotros
A veces veo esas listas tipo "razones para no votar por Kast" y, estoy de acuerdo con todas,pero al mismo tiempo esas son todas las razones por las que mi mamá si vota por Kast (anti inmigracion, reducción del sueldo minimo, anti aborto, etc). Como izquierda tenemos q entender como piensa la derecha

“While the AI industry claims its models can “think,” “reason,” and “learn,” their supposed achievements rest on marketing hype and stolen intellectual labor. In reality, AI erodes academic freedom, weakens critical reading, and subordinates the pursuit of knowledge to corporate interests.”
AI Is Hollowing Out Higher Education
Olivia Guest & Iris van Rooij urge teachers and scholars to reject tools that commodify learning, deskill students, and promote illiteracy.

extraño trabajar con estudiantes universitarios de chile, lo gringos del maple son full clientes de la universidad. La actividad política es casi nula y se gasta mucho tiempo en pelear las notas en vez del aprendizaje. Obviamente, la culpa la tiene la estructura que te pone 400 cabros en una sala

and then they hit you back with a "oh, so you don't like my wording", and I mean, yeah, because what they say is wrong or imprecise, not just because I have a liking for other words or a different order of them.
It is hard to grade university assignments when it is clear that what a lot of the students need first is some highschool level writing and computer classes. Like, I'm not grading them on that, but it causes some very consistent mistakes of the "you're not saying what you think you're saying" kind

One of the best things about finishing the phd is that I don't have to do any more research😂, I'm so done with the whole system, high effort, the professional risk of narrowing your possibilities, not so great rewards

Crazy to think I'll be defending my dissertation in a week. It is also crazy to think about how ANN's have become so relevant since I started. I remember when connectionism used to be this weird dead thing, and while that is still true (lol), concepts from the field have regained importance.

I think this is true in a deep and troubling way. I have been observing this too. I am getting old & maybe I’m wrong, but I really feel basic academic, critical and intellectual, attitudes that were normal and prominent 20 years ago seem to have eroded. I agree, we need to understand how and why.
The scenario in which there are oligarchs powerful enough to succeed at their AI con and force LLMs onto the rest of society is the outright fascist and dystopian scenario. That higher ed has largely capitulated to the scam means it had already been deskilled. We need to understand how and why.
“Ultimately, the collective strategy of AI companies threatens to deskill precisely those people who are essential for society to function(…) automation of knowledge and culture by private companies is a worrying prospect – conjuring dystopian and outright fascistic scenarios.” — @olivia.science

important on LLMs for academics:
1️⃣ LLMs are usefully seen as lossy content-addressable systems
2️⃣ we can't automatically detect plagiarism
3️⃣ LLMs automate plagiarism & paper mills
4️⃣ we must protect literature from pollution
5️⃣ LLM use is a CoI
6️⃣ prompts do not cause output in authorial sense

A unique selling point of these systems is conversing and writing in a human-like way. This is imminently understandable, although wrong-headed, when one realises these are systems that
essentially function as lossy2
content-addressable memory: when
input is given, the output generated by the model is text that
stochastically matches the input text. The reason text at the output looks novel is because by design the AI product performs
an automated version of what is known as mosaic or patchwork
plagiarism (Baždarić, 2013) — due to the nature of input masking and next token prediction, the output essentially uses similar words in similar orders to what it has been exposed to. This
makes the automated flagging of plagiarism unlikely, which is
also true when students or colleagues perform this type of copypaste and then thesaurus trick, and true when so-called AI plagiarism detectors falsely claim to detect AI-produced text (Edwards, 2023a). This aspect of LLM-based AI products can be
seen as an automation of plagiarism and especially of the research paper mill (Guest, 2025; Guest, Suarez, et al., 2025; van
Rooij, 2022): the “churn[ing] out [of] fake or poor-quality journal papers” (Sanderson, 2024; Committee on Publication Ethics,](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:vsyj5jtayxcq5dw5mtja4xtb/bafkreieufyngjbrn23zkmesrimcwemxkxtaf2x7d3bedjt7bg65htgtkrm@jpeg)
