Conferences ought to be venues where small communities of researchers can gather for a few days, hear about new work, and discuss new ideas one-on-one. You can't do that when there are multiple tracks, spotlight talks, poster sessions where authors aren't present, etc.

My personal feeling is, for any theory, the best way to keep its vitality is to constantly revise it whenever new insights are systematically available, and this is exactly what Chomsky and his collegues have been doing, the traction is simply the natural consequence of this.

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
5 Ghostwriter in the Machine
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,Either way, even if
the courts decide in the favour of companies, we should not allow
these companies with vested interests to write our papers (Fisher
et al., 2025), or to filter what we include in our papers. Because
it is not the case that we only operate based on legal precedents,
but also on our own ethical values and scientific integrity codes
(ALLEA, 2023; KNAW et al., 2018), and we have a direct duty to
protect, as with previous crises and in general, the literature from
pollution. In other words, the same issues as in previous sections
play out here, where essentially now every paper produced using
chatbot output must declare a conflict of interest, since the output text can be biased in subtle or direct ways by the company
who owns the bot (see Table 2).
Seen in the right light — AI products understood as contentaddressable systems — we see that framing the user, the academic
in this case, as the creator of the bot’s output is misplaced. The
input does not cause the output in an authorial sense, much like
input to a library search engine does not cause relevant articles
and books to be written (Guest, 2025). The respective authors
wrote those, not the search query!

This afternoon, I will give a public lecture about #ResearchIntegrity and #ImageForensics, at the University of Bern, CH, where I will receive an honorary doctorate from the Faculty of Science tomorrow. Thank you for your support ❤️
Screenshot from a flyer that reads: 
Public Lecture on Scientific Integrity
Dr. Elisabeth Bik
Errors and Misconduct in
Biomedical Research
Images
Science builds upon science. Even after peer-review and publication, science papers could still contain
images or other data of concern. If not addressed, papers containing incorrect or even falsified data
could lead to wasted time and money spent by other researchers trying to reproduce those results.
Several high-profile cases of science misconduct have been reported, but many more remain
undetected. Elisabeth Bik is an image forensics detective who left her paid job in industry to search for
and report biomedical articles that contain errors or data of concern. She has conducted a systematic
review of 20,000 papers across 40 journals and found that approximately 4% of these contained
inappropriately duplicated images. In her talk, she will present her work and show several types of
inappropriately duplicated images and other examples of research misconduct. In addition, she will
discuss how Artificial Intelligence can both help identify cases of misconduct and also create them, as
well as the growing threat of scientific paper mills.
On the occasion of the Dies academicus of the University of Bern on 6th December 2025,
Elisabeth Bik will receive an honorary doctorate from the Faculty of Science for her
groundbreaking work and untiring commitment to scientific integrity.
