New: Trio of Dem senators urge Apple and Google to enforce their own terms of service and ban X, Grok apps for their flood of nonconsensual sexual imagery.
I've repeatedly asked both Apple and Google about this for three days. They're completely silent, seemingly hoping the question just goes away.

Senators urged Apple and Google to remove X and Grok from app stores over sexual deepfakes
“Turning a blind eye to X’s egregious behavior would make a mockery of your moderation
practices,” three Democratic senators wrote to Apple’s and Google’s CEOs.

Yann LeCun has long proclaimed LLMs to be a dead-end research strategy, at least if we are after a technology that can successfully mimic intelligent behavior. Looks like he is finally putting his money where his mouth is and fleeing the sinking ship.

The progenitor of Go and UTF-8 would like a word:
Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software.
Just fuck you. Fuck you all.
I can't remember the last time I was this angry.

to me
Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)

close observations of my most traditionally successful peers suggests much academic productivity is driven by a desire to be seen as really smart
this has put me at a profound career disadvantage, because, more like a normal person, I just want people to think I'm hot and a good cook

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.

'whether LLMs can make “scientific discoveries” is no more interesting a question than whether Galileo’s telescope “really saw.” The better question is whether LLMs can be usefully integrated in the processes by which scientific knowledge gets made, validated, and disseminated.'

The Pennsylvania Department of Transportation (PennDOT) does not keep the trains and trams running. It will not retitle my vehicle. It does not plow the streets of Pennsylvania. If PennDOT maintains neither the public transit nor the vehicular transit infrastructure, does it actually exist?

Important post: my colleague documents an “official, nationwide policy of intimidating and threatening people who attempt to observe and record DHS operations,” or who peacefully and without interference follow and protest them, even though the First Amendment broadly protects doing those things. /1
On Dec. 4, DOJ labeled people who impede or "dox" ICE agents "domestic terrorists." I document how DHS believes following, recording, and protesting agents is "impeding," and has a policy of threatening & arresting ICE observers. That's unconstitutional. www.cato.org/blog/dhs-pol...
