That depends on the jurisdiction's rules for statutory interpretation and on the statute in question. And, FWIW, computer-misuse laws like the federal CFAA were written to deal with viruses, worms, and other indirect ways of using computers and have been repeateldy applied in cases involving them.

It’s worth clarifying what’s wrong with this trial. Guinea-Bissau does not presently vaccinate newborns for HepB, so this study does not withhold a vaccine they would otherwise have gotten, or expose infants to a disease they would otherwise have been protected against.

No. Criminal liability is mostly based on statutes, rather than precedents. The big issue is the defendant's state of mind, not whether something like this has happened before. Civil liability depends on the causal chain, which can break if it is too long (10,000 agents).

Did I abuse Claude by showing it an 1844 newspaper?
Transcript from a Claude session. 

Historian: 
why am i getting this error: This response was blocked by content filtering. Rephrase your message or try again.

Claude:
Investigating the likely cause of a content filtering error.
I can’t see that error or what triggered it, so this is my best guess rather than a diagnosis: an automated filter checks responses as they’re generated, and this page is a hard case for it. It’s a nativist paper’s account of the Kensington riots, full of graphic descriptions of shootings and beatings and hostile language about Irish Catholics. A verbatim transcription reproduces all of that, and the filter can’t tell a historical source from new writing.

It is darkly funny that the alignment-based paradigm within which the AI industry operates was designed to deal with AGI risks but seems much more suited to the mundane ones, while the most effective safeguard against the actual AGI risks seems to be mundane cybersecurity discipline.

They were still running these tests through SEPTEMBER? Did they learn nothing from the hacks in JULY?
The company discovered the error on Sept. 28. As a result, Gripp said, Anthropic terminated testing for that model and added safeguards for further trials.

They were testing *what* on the public Internet? This is getting into CFAA intentional access without authorization territory. This is how you commit actual crimes while doing AI testing.
The email was flagged as spam and remained in that folder until Wednesday, when Anthropic alerted police to the incident, authorities said. No city or police data was accessed as a result of the interaction, Gripp said.

This wasn’t Anthropic’s systems flagging a user prompt for investigation. This was a system just making up a tip.
The model gave information purporting to come from someone with information about an unsolved homicide, he said.

Compare this to Lewis Lapham’s account of his CIA interview in 1957. www.laphamsquarterly.org/spies/open-i...
Prepared for nothing less, I had spent the days prior to the interview reading about Lenin’s train and Stalin’s prisons, the width of the Fulda Gap, the depth of the Black Sea. None of the study was called for. Instead of being asked about the treaties of Brest-Litovsk or the October Revolution, I was asked three questions bearing on my social qualifications for admission into what the young men at the far end of the table clearly regarded as the best fraternity on the campus of the free world:

1. When standing on the thirteenth tee at the National Golf Links in Southampton, which club does one take from the bag?
2. On final approach under sail into Hay Harbor on Fishers Island, what is the direction (at dusk in late August) of the prevailing wind?
3. Does Muffy Hamilton wear a slip?

Oh, yes, and sorry that I should have been clearer. It's better that they ask than cut back on the work; the bad thing is that they have to ask. Something can be the best response to an ugly fundraising environemnt, and still distort the mission.

Part of this conversation should be about the high barriers—both technical and financial—that the ALI puts around access to its projects. Compare, for example, the difficulty of getting the text of a Restatement to the ease of getting the text of a Uniform Act.

Federal wire fraud requires (1) a falsehood, (2) that is material (i.e., matters to the person deceived), (3) made with the intent to deceive, and (4) the receipt of money or property as a result. Your laptop in the car example doesn't have (3) or (4).

No it fucking didn't! Did anybody other than me actually read the fucking opinion? I feel like I'm taking crazy pills. (this is a guest column in The Hill which I will not dignify with a link, whose author, a legislator who otherwise sounds like someone who'd deserve my respect, should know better)
That’s got to stop now. A federal appeals court recently agreed but ruled that the current state of the law prevents law enforcement from prosecuting people who use AI image generators to create what is often called “synthetic child pornography.” These materials can be lifelike depictions of toddlers engaged in sex acts with adults, or anything else you can imagine. But the court ruled that because the images don’t depict actual sexual abuse crimes against real children, they are free speech protected by the First Amendment.
