Looks like LLMs are *very* vulnerable to attack via poetic allusion: "curated poetic prompts yielded high attack-success rates (ASR), with some providers exceeding 90% ..."

This is why AI isn't going to turn out like businesses think. Like a toddler they believe that the environment won't respond back.
When an AI-powered writing tool was rolled out on a job site, the length of proposals exploded. Signals employers used to identify good candidates — like quality of writing, and relevance of experience — became ubiquitous. That was OK for bad candidates, but terrible for good ones.

Claiming AI agents have autonomy is like me claiming my oven roasts a chicken on its own, between me putting it in and taking it out.

Duolingo’s increasing desperation to sell me their AI enhanced version is getting kind of off putting. Mates, make it part of the core offering or move on.

It's fascinating to me about how the intentions of the AI companies (fire all the people) and the uptake of AI in business (get it to do the work of people we fired already) are in conflict.

“Current architectures of LLMs cannot imagine, but they can sequence … For the same reason that a dog can go to church but a dog cannot be Catholic, an LLM can have a conversation but cannot participate in the conversation.”
I've been re-acquainting myself with NNs, transformers and LLMs this week, so these are early thoughts. But I am starting to think about language without the capacity to imagine language, i.e., an LLM unable to imagine itself participating in language. mail.cyberneticforests.com/what-machine...

Nice illustration of AI and Jevons' paradox. AI makes the amount of cases in Brazilian legal system go up.
“We note that the use of AI, in the end, rather than diminishing litigation, is increasing it…[AI] may be a solution, but no one’s sure if it will actually work.”
AI is helping judges to quickly close cases, and lawyers to quickly open them
Brazil’s overburdened courts and lawyers are adopting artificial intelligence. But experts wonder whether it serves justice.

Generative AI is 1st new tech marketed in post-Moore's Law era.
In previous decades, if new digital tech needed more or cheaper computing power to work & make economic sense, a few more years of Moore's law would solve.
But exponential growth in transistor density is stalling now...
