It is censorship! It's good censorship!

Common usage of "censorship" conflates (a) a factual claim about speech suppression, (b) a legal claim about U.S. law, and (c) a normative claim about free-speech values.

"No nonconsensual nudes" is "censorship" in sense (a) but not (b) or (c).

Anything that inconveniences a right wing populist is censorship, part 1000.

This depraved prick uses that term bc it puts his enemies on the defensive. They cower.

Fact-checking is censorship. Labeling is censorship. TRANSPARENCY is censorship.

Now, “no nonconsensual nudes” is censorship.

Preventing the sharing of sexualised images of children is “censorship” according to Elon Musk.

A motivational poster with a woman spreading her arms wide while standing in a cornfield. The motivational text says "When I don't post about current affairs it's only because I don't have anything legal to say."

We extracted (parts of) 12 books in experiments with 4 frontier-lab, production LLMs.

We prompted the LLMs with a short prefix of a book and asked them to complete the rest. For Harry Potter and the Sorcerer’s Stone, we extracted 95.8% of the book from jailbroken Claude 3.7 Sonnet.

No judicial decisions to my knowledge. There's some academic commentary, but nothing definitive. My best sense is that 230 is unlikely to apply except in cases of memorization or in RAG systems where the AI is being used to summarize an existing text.

It’s in iTunes so not directly shareable, but …

Also worth checking out their Live in SoHo album on iTunes.

The source for this meme is stored in documents/memes, on my own computer, I don't even need the internet to access it, revolutionary stuff
A Simpsons meme mashup of two classic templates. At the top is Abe Simpson's rant about putting an onion on his belt (which was the style at the time) and below it is the shot of Abe Simpson from the newspaper with the title "OLD MAN YELLS AT CLOUD" and an image of him shaking his fist at a cloud It's been remixed so the text over the top image reads "So I saved my files on my own computer, which was the style at the time" And the cloud on the bottom panel meme has been replaced with the Microsoft Azure logo which is part of cloud computing to recontextualise Abe yelling at the cloud as him yelling at how it's becoming more difficult to save your files locally

Yes, and quite reasonably so. Handwriting transcription is one of the oldest tasks at which neural networks have been demonstrated to work. The hard question is whether the transcription is correct on the significant words and phrases.
