I think about this finding a lot: "Students whose school uses AI for many reasons are more likely to report that they or a friend of theirs has had a back-and-forth conversation with AI, like chatbots, in potentially troubling ways." From @cdt.org's report:
Hand in Hand: Schools’ Embrace of AI Connected to Increased Risks to Students
Artificial intelligence (AI) has continued to alter the educational experiences of teachers, students, and parents during the 2024-25 school year. The frequency and variety of AI uses continues to gro...

Hypervisible @hypervisible.blacksky.app · yesterday“…the researchers found that opening up to chatbots about personal issues made some people feel not better but worse.”
I wrote about the Trojan horse, and what we can learn from her mouth about different cultural attitudes towards deception and violence. As someone comments below, the phrase GIFT ARTICLE is pretty scary in this context.

Hey yeah time to dust off those 2020 tweets about how PEOPLE WITH UNDERLYING HEALTH ISSUES DESERVE TO LIVE TOO, YOU ABSOLUTE GHOULS.
The New York Times@nytimes.com · 2d agoBreaking News: Two deaths in Michigan have been linked to cyclospora. Both people who had the parasite also had underlying health issues.
It's genuinely upsetting to see high level mathematicians be so un credulous at the motives of big tech. No ethical thoughts at all, seemingly. Just oh look this shiny toy they were "nice" enough to give me spat out a theorem.
i think a lot about this thing thurston says in "on proof and progress in mathematics" 🧮 arxiv.org/pdf/math/940...
What is higher education if not "a particular vision of social change"

I was curious so I looked up one of the popular Calculus books (Stewart), and Amazon lists it for $277 🤡. Good thing there are plenty of great resources out there, like our TBIL Calculus activity book or Active Calculus, that are free and open.
Jennifer N. Victor@jenvictor.bsky.social · 6d agoToday, in middle-aged academics' rage, I learned that a paperback version of the course textbook I've used for 20+ years costs $265!! The electronic version, which requires students to read it through the publisher's proprietary software interface, is $98. RIP books! 😩
And now thanks to the beauty of open source / open access, you can view the electronic version of Linear Algebra for @tbil.org online for free: tbil.org/library/ Also includes materials for Precalculus and Calculus!

Hillary Monahan@hillarymonahan.bsky.social · last wk.Nobody wants predictive data models to stop working for the people in medicine. Or translating ancient Pompeii texts. Or the other ways we were already using it. We want it to stop replacing workers, killing the environment, and stealing from artists. Hope that clarifies.

Is it time to start writing your course materials? Want to make them accessible? We are hosting a few free workshops in the next weeks to help you do just that with PreTeXt. And using PreTeXt.Plus means nothing to install and no GitHub required. Info here: pretext.plus/announcement...
PreTeXt.Plus | Writing Accessible Course Materials with PreTeXt: workshops in July & August 2026 | Office Hours at MAA MathFest
To help our colleagues adopt PreTeXt to meet this need (whether via the PreTeXt.Plus app, or a local install of PreTeXt's free and open source software), we're excited to offer several virtual workshops this July and August.

An autistic man with a special interest in the Harry Potter series has made the decision to value the lives and dignity of his trans friends more than a book about a wizard who grows up to be a cop, sources have reported.

13. Hence our dismal conclusion: rather than finding that LLMs free us to do a better job of what we were doing before they came along, they shift scientific incentives (and the playing field of academic competition) in ways that compel us to do more and more, faster and faster, less and less well.
Apparently my hot take of the day is that time spent trying (and failing) to prove a conjecture is not wasted effort, even if it turns out to be that the conjecture was false.
ꭓle Ormsby 𓆙@motivickyle.bsky.social · 2w agoSorry to Contribute to Discourse, but maybe it’s Good and Useful for the Field and Human Mathematicians if Machines pick off counterexamples to conjectures, thus correcting and refining our view of the Mathematical Landscape. Less wasted Human Effort and a clearer Path Forward.
Being unable to say “I don’t know” is fundamentally incompatible with education and it would be nice if even a single senior leader of a university understood that.
Talk about burying the lede... a counterexample to the Jacobian conjecture in dimension 3 has been found with the help of AI. And it is only degree 6! xenaproject.wordpress.com/2026/07/20/h...

The algorithms are inundating me tonight with content from self-described "autism parents*", and I just really wish they would accurately describe themselves instead as neurotypical (or allistic) parents of autistic kids.

"I don't like being called cis" "I don't like being called white" "I don't like being called abled" That's because you view yourself as "normal" or "the default" and everyone else as *not*. Viewing yourself as the baseline is just another form of prejudice. It's just a more implicit type.

Read the whole thing, but this is really spot on. "It is dismaying to watch campus pour money into a technology that is cannibalizing student achievement across its disciplines."
Dave Kung@dtkung.bsky.social · 3w agoListen to the students: "New technologies have harmed student learning at both the HS and collegiate levels. To focus on the SAT...misses the point: Student achievement will continue to decline as long as more fundamental barriers to student success persist." www.dailycal.org/opinion/edit...
