Tim Cook is “not 100 percent” sure Apple can stop AI hallucinations

This is a most excellent place for technology news and articles.
As others are saying it's 100% not possible because LLMs are (as Google optimistically describes) "creative writing aids", or more accurately, predictive word engines. They run on mathematical probability models. They have zero concept of what the words actually mean, what humans are, or even what they themselves are. There's no "intelligence" present except for filters that have been hand-coded in (which of course is human intelligence, not AI).
"Hallucinations" is a total misnomer because the text generation isn't tied to reality in the first place, it's just mathematically "what next word is most likely".

Remember the game people used to play that was something like "type my girlfriend is and then let your phone keyboards auto suggestion take it from there?" LLMs are that.
An LLM once explained to me that it didn't know, it simulated an answer. I found that descriptive.
I was wondering, are people working on networks that train to create a modular model of the world, in order to understand it / predict events in the world?
I imagine that that is basically what our brains do.
Many attempts, some well-funded.
They have been successful in very limited domains. For example, the F-35 integrated sensor suite.
Now I know why they crash so often
Not really anything properly universal, but a lot of task specific models exists with integration with logic engines and similar stuff. Performance varies a lot.
You might want to take a look at wolfram alpha's plugin for chatgpt for something that's public
Yeah I'm sure folks are working on it, but I'm not knowledgeable or qualified on the details.
They do have internal concepts though: https://www.lesswrong.com/posts/yzGDwpRBx6TEcdeA5/a-chess-gpt-linear-emergent-world-representation
Probably not of what a human is, but thought process is needed for better text generarion and is therefore emergent in their neural net
Ok, maybe there's a possibility someday with that approach. But that doesn't reflect my understanding or (limited) experience with the major LLMs (ChatGPT, Gemini) out in the wild today. Right now they confidently advise ingesting poison because it's grammatically sound and they found it on some BS Facebook post.
If ML engineers can design an internal concept of what constitutes valid information (a hard problem for humans, let alone machines) maybe there's hope.
Ethical and healthy is a whole harder problem lol. Having reasoning and thinking will come before
The problem is they have many different internal concepts with conflicting information and no mechanism for determining truthfulness or for accuracy or for pruning bad information, and will sample them all randomly when answering stuff
Indeed
all we know about ourselves is what's in our memories. the way normal writing or talking works is just picking what words sound best in order
That's not the whole story. "The dog swam across the ocean." is a grammatically valid sentence with correct word order. But you probably wouldn't write it because you have a concept of what a dog actually is and know its physiological limitations make the sentence ridiculous.
The LLMs don't have those kind of smarts. They just blindly mirror what we do. Since humans generally don't put those specific words together, the LLMs avoid it too, based solely on probability. If lots of people started making bold claims about oceanfaring canids (e.g. as a joke), then the LLMs would absolutely jump onboard with no critical thinking of their own.
Humans do the same thing. Have you heard of religion?
Have you heard of music theory and psychoacoustics (frankly even painting with oil you'll use that)? Where we hear something dependent on what we expect and what we actually get, both in time, in length, in color, in amplitude etc.
Religion is about the same, it uses the concepts of impossible, unreachable and transcendent. Kicking something left and then back into place is not the same as not touching it.
