CEO of Google Says It Has No Solution for Its AI Providing Wildly Incorrect Information

You know how Google's new feature called AI Overviews is prone to spitting out wildly incorrect answers to search queries? In one instance, AI Overviews told a user to use glue on pizza to make sure the cheese won't slide off (pssst...please don't do this.)
Well, according to an interview at The Vergewith Google CEO Sundar Pichai published earlier this week, just before criticism of the outputs really took off, these "hallucinations" are an "inherent feature" of AI large language models (LLM), which is what drives AI Overviews, and this feature "is still an unsolved problem."
They keep saying it's impossible, when the truth is it's just expensive.
That's why they wont do it.
You could only train AI with good sources (scientific literature, not social media) and then pay experts to talk with the AI for long periods of time, giving feedback directly to the AI.
Essentially, if you want a smart AI you need to send it to college, not drop it off at the mall unsupervised for 22 years and hope for the best when you pick it back up.
No he's right that it's unsolved. Humans aren't great at reliably knowing truth from fiction too. If you've ever been in a highly active comment section you'll notice certain "hallucinations" developing, usually because someone came along and sounded confident and everyone just believed them.
We don't even know how to get full people to do this, so how does a fancy markov chain do it? It can't. I don't think you solve this problem without AGI, and that's something AI evangelists don't want to think about because then the conversation changes significantly. They're in this for the hype bubble, not the ethical implications.
We do know. It's called critical thinking education. This is why we send people to college. Of course there are highly educated morons, but we are edging bets. This is why the dismantling or coopting of education is the first thing every single authoritarian does. It makes it easier to manipulate masses.
You’re exactly right. There is a similar debate about automated cars. A lot of people want them off the roads until they are perfect, when the bar should be “until they are safer than humans,” and human drivers are fucking awful.
Perhaps for AI the standard should be “more reliable than social media for finding answers” and we all know social media is fucking awful.
We haven't even been able to eliminate religious thought patterns, human minds attach to stories not facts. We are a sad alpha version of sentience and I sincerely hope the next version isn't so fundamentally broken.
I let you in on a secret: scientific literature has its fair share of bullshit too. The issue is, it is much harder to figure out its bullshit. Unless its the most blatant horseshit you've scientifically ever seen. So while it absolutely makes sense to say, let's just train these on good sources, there is no source that is just that. Of course it is still better to do it like that than as they do it now.
Google AI suggested you put glue on your pizza because a troll said it on Reddit once...
Not all scientific literature is perfect. Which is one of the many factors that will stay make my plan expensive and time consuming.
You can't throw a toddler in a library and expect them to come out knowing everything in all the books.
AI needs that guided teaching too.
"Most published journal articles are horseshit, so I guess we should be okay with this too."
I'm addition to the other comment, I'll add that just because you train the AI on good and correct sources of information, it still doesn't necessarily mean that it will give you a correct answer all the time. It's more likely, but not ensured.
Yes, thank you! I think this should be written in capitals somewhere so that people could understand it quicker. The answers are not wrong or right on purpose. LLMs don't have any way of distinguishing between the two.
I'm a mathematician who's been following this stuff for about a decade or more. It's not just expensive. Generative neural networks cannot reliably evaluate truth values; it will take time to research how to improve AI in this respect. This is a known limitation of the technology. Closely controlling the training data would certainly make the information more accurate, but that won't stop it from hallucinating.
The real answer is that they shouldn't be trying to answer questions using an LLM, especially because they had a decent algorithm already.
Yeah, I've learned Neural Networks way back when those thing were starting in the late 80s/early 90s, use AI (though seldom Machine Learning) in my job and really dove into how LLMs are put together when it started getting important, and these things are operating entirelly at the language level and on the probabilities of language tokens appearing in certain places given context and do not at all translate from language to meaning and back so there is no logic going on there nor is there any possibility of it.
Maybe some kind of ML can help do the transformation from the language space to a meaning space were things can be operated on by logic and then back, but LLMs aren't a way to do it as whatever internal representation spaces (yeah, plural) they use in their inners layers aren't those of meaning and we don't really have a way to apply logic to them).
So with reddit we had several pieces of information that went along with every post.
User, community along with up, and downvotes would inform the majority of users as to whether an average post was actually information or trash. It wasn't perfect, because early posts always got more votes and jokes in serious topics got upvotes, bit the majority of the examples of bad posts like glue on food came from joke subs. If they can't even filter results by joke sub, there is no way they will successfully handle saecasm.
Only basing results on actual professionals won't address the sarcasm filtering issue for general topics. It would be a great idea for a serious model that is intended to only return results for a specific set of topics.
It’s worse than that. “Truth” can no more reliably found by machines than it can be by humans. We’ve spent centuries of philosophy trying to figure out what is “true”. The best we’ve gotten is some concepts we’ve been able to convince a large group of people to agree to.
But even that is shaky. For a simple example, we mostly agree that bleach will kill “germs” in a petri dish. In a single announcement, we saw 40% of the American population accept as “true” that bleach would also cure them if injected straight into their veins.
We’re never going to teach machine to reason for us when we meatbags constantly change truth to be what will be profitable to some at any given moment.
no, the truth is it's impossible even then. If the result involves randomness at its most fundamental level, then it's not reliable whatever you do.
Sure, the AI is never going to understand what it's doing or why, but training it on better datasets certain WILL improve the results.
Garbage in, garbage out.
That's just not how LLMs work, bud. It doesn't have understanding to improve, it just munges the most likely word next in line. It, as a technology, won't advance past that level of accuracy until it's a completely different approach.
Or you could just not use LLMs for this.
The truth is, this is the perfect type of a comment that makes an LLM hallucinate. Sounds right, very confident, but completely full of bullshit. You can't just throw money on every problem and get it solved fast. This is an inheret flaw that can only be solved by something else than a LLM and prompt voodoo.
They will always spout nonsense. No way around it, for now. A probabilistic neural network has zero, will always have zero, and cannot have anything but zero concept of fact - only stastisically probable result for a given prompt.
It's a politician.
They could also perform some additional iterations with other models on the result to verify it, or even to enrich it; but we come back to the issue of costs.
Also once you start to get AI that reflects on its own information for truthfulness, where does that lead? Ultimately to determine truth you need to engage with the meaning of the words, and the process inherently involves a process of self-awareness. I would say you're talking about treaching the AI to understand context, and there is no predefined limit to the layers of context needed to understand the truthfulness of even basic concepts.
An AI that is aware of its own behaviour and is able to explore context as far as required to answer questions about truth, which would need that exploration precached in some sort of memory to reduce the overhead of doing this from first principles every time? I think you're talking about a mind; a person.
I think this might be a fundamental barrier, which I would call the "context barrier".
I think you’re right that with sufficient curation and highly structured monitoring and feedback, these problems could be much improved.
I just think that to prepare an AI, in such a way, to answer any question reliably and usefully would require more human resources than there are elementary particles in the universe. We would be better off connecting live college educated human operators to Google search to individually assist people.
So I don’t know how helpful it is to say “it’s just expensive” when the entire point of AI is to be lower cost than a battalion of humans.
Why not solve it before training the AI?
Simply make it clear that this tech is experimental, then provide sources and context with every result. People can make their own assessment.
Because a lot of people won't look at sources even if you serve them up on a silver platter?
