Nobody wants to admit it but "vibecoding" works until your app has actual users. Then you discover what senior engineers have been getting paid for.

Students need ChatGPT because how could you possibly write a 1500 word essay yourself in only 11 weeks?

A PhD's success depends more on the fit between the student, the advisor, and the lab than on the specific topic being studied (it barely matters at all). Similarly, a lab's success depends more on how excited (or miserable) its researchers are than on the precise project they are working on (it could be virtually anything). This information isn't in papers or in grant proposals, you have to ask the researchers.

🦔UC Berkeley's computer science department just posted its worst failure rates in years. 35.3% of CS 10 students got F's in spring 2026, up from under 10% in prior semesters. Professor Dan Garcia says the primary driver is a "vast increase in academic dishonesty" through LLMs. Students use AI to complete assignments, never learn the material, then fail exams. His office hours, once full, are now empty. My Take Companies are firing experienced engineers while the pipeline that produces new ones is being gutted by the same technology. Students use AI to bypass the hard part of learning, show up to exams without the understanding, and fail. One professor discovered a student's linear algebra class had an "open AI" policy for homework and exams. That student then couldn't do basic linear algebra in the next course. Both ends of the workforce are eroding at the same time. Senior engineers are getting cut to fund AI spending. Junior engineers are graduating without the skills because AI did their coursework. And the companies spending trillions on these tools haven't connected those two facts yet. Hedgie🤗

A lot of scholars don’t understand why publishing LLM hallucinated bullshit is unacceptable because it’s only a degree of kind away from the bullshit already normalized in their fields. This economist just straight up admits it.
I've gotten a lot of comments like this, so forgive me if this isn't very kind, but I'm at my limit. If you're a serious academic, you've spent a lot of time looking at citations, and you know they often contain errors. You know that it's very common for professors just to copy citations they found in other papers and put them into their own papers because they need a lot of citations to look credible. Given that this is going on, it's kind of silly to think that we should have a kind of death penalty for having an LLM, hallucination mistake What you're doing is virtue signaling and pretending that citations are somehow sacred to what academics do, when in fact they're mostly just poorly put up window dressing. You're being dishonest. Perhaps with yourself, perhaps with me.

The arXiv one-year ban reveals that a lot of people who submit papers don't like...doing research. Reading papers is fun. Talking about papers in a group is interesting. Synthesizing the literature is rewarding. There are lot of careers don't involve those things & pay better.

A one-year ban for submitting totally fake nonsense as though it were real research is *insultingly* lenient. Do *you* want to waste your time reading papers by the guy who got caught committing fraud eighteen months ago?
The reactions of many researchers on finally being held responsible for having read the very paper they submitted are... something.

Citations supply research support for a point made in a paper. So fake citations are literally lies, not typos. You can correct a typo in your head, interpret it to figure out what the author really meant. The presence of hallucinated citations means you can't trust the author.

Citing an AI hallucinated source that doesn’t exist is not equivalent to a typo.
Replying to @Zeke_Darwin
I think this is a pretty bad heuristic. Sometimes errors slip through; would you say that a paper with a factual error or a typo is no longer trustworthy? Should someone who publishes a paper with an inessential error be banned for life from publishing preprints?
