Marketing hype.
No amount of training can ever eliminate the need for human curation. This is not AI, it's a jumped up pattern recognition engine. False positives and false negatives are inevitable without a consciousness to evaluate it. Hallucinations are an intractable problem that can not be solved, regardless of training, and so all these AI can ever be is a tool for human workers.
It'll take something totally different and new.
I understand what you are saying but I dont agree, look at the examples we already have: I use chatgpt at work to code, it has limitations but works without any human curation. Check midjourney as well, it has great accuracy and if you ask a picture of dogs it will create without any human intervention. Yes, it took a long time and human effort to train them, but in the end it is not needed anymore for the majority of the cases. What you say about hallucinations, innacurate results, they happen yes, but ita becoming fringe cases and less and less. Its true that its not the miracle tool that marketing says it is, thats marketing, but its much more dangerous than it looks and will definetly substitute a lot of workers, it already does.
LLMs may fabricate things now and then but so do humans. I am not convinced the problem is intractable.
You have no reason to believe the problem can be solved.
It's almost religious. You just have faith in technology you don't understand.
Keep praying to your machine spirits, maybe the Omnissiah will deliver the answer!
I have no reason to believe the problem can't be solved, except insofar as it hasn't been solved yet (but LLMs only recently took off). So without a good reason to believe it's intractable, I'm at worst 50/50 on if it can be solved. Faith in the machine spirit would be if I had an unreasonably high expectation LLMs can be made not to hallucinate, like 100%.
My expectation is around 70% that it's solvable.
You have no reason to think it can be solved. You're just blindly putting your faith in something you don't understand and making up percentages to make yourself sound less like a religious nut.
If I have no reason to believe X and no reason not to believe X, then the probability of X would be 50%, no?
By this logic, the probability of every stupid thing is 50%
You have no reason to believe magic is real, but you have no reason to not believe magic is real. So, is there a 50% probability that magic is real? Evidently you think so, because the magic science mans are going to magic up a solution to the problems faced by these chatbots.
Absolutely not true. The probabilities of stupid things are very low; that's because they are stupid. If we expected such things to be probable, we probably wouldn't call them stupid.
I have plenty of evidence to believe magic isn't real. Don't mistake "no evidence (and we haven't checked)" for "no evidence (but we've checked)". I've lived my whole life and haven't seen magic, and I have a very predictive model for the universe which has no term for 'magic'.
LLMs are new, and have made sweeping, landmark improvements every year since GPT2. Therefore I have reason to believe (not 100%!) that we are still in the goldrush phase and new landmark improvements will continue to be made in the field for some time. I haven't really seen an argument that hallucination is an intractable problem, and while it's true that all LLMs have hallucinated so far, GPT4 hallucinates much less than GPT3, and GPT3 hallucinates a lot less than GPT2.
But realistically speaking, even if I were unknowledgeable and unqualified to say anything with confidence about LLMs, I could still say this: for any statement X about LLMs which is not stupid by the metric that an unknowledgeable person would be able to perceive, the probability of that statement being true about LLMs to an unknowledgeable person is 50%. We know this because the opposite of that statement, call it ¬X, would also be equally opaque to an unknowledgeable person. Given X and ¬X are mutually exclusive, and we have no reason to favor one over the other, both have probability 50%.
This technology isn't actually that new, it's been around for almost a decade. What's new is the amount of processing power they have to throw at the data bases and the level of data collection, but you're just buying into marketing hype. It's classic tech industry stuff to over promise and under deliver to pump up valuations and sales.
Ok, but by that same perspective, you could say convolutional neural networks have been around since the 80s. It wasn't until Geoffrey Hinton put them back on the map in 2012ish that anyone cared. GPT2 is when I started paying attention to LLMs, and that's 5 years old or so.
Even a decade is new in the sense of Laplace's law of succession alone indicating there's still a 10% chance we'll solve the problem in the next year.
Laplace’s law of succession only applies if we know an experiment can result in either success or failure. We don't know that. That's just adding new assumptions for your religion. For all we know, this can never result in success and it's a dead end.
I have to hard disagree here. Laplace's law of succession does not require that assumption. It's easy to see why intuitively: if it turns out the probability is 0 (or 1) then the predicted probability from Laplace's law of succession limits to 0 (or 1) as more results come in.
If the probability is 0 then it will never be 1
Therefore, there must be some probability of success.
It may help to distinguish between the "true" probability of an event and the observer's internal probability for that event. If the observer's probability is 0 or 1 then you're right, it can never change. This is why your prior should never be 0 or 1 for anything.
For anything? Are you sure about that?
Because I say there's 0 probability that six sided dice will ever produce a 7.
A better example of this is "how sure are you that 2+2=4 ?" It makes sense to assign a prior probability of 1 to such mathematical certainties, because they don't depend on our uncertain world. On the other hand, how sure are you that 8858289582116283904726618947467287383847 isn't prime?
For a die in a thought experiment -- sure, it can't be 7. But in a physical universe, a die could indeed surprise you with a 7.
More to the point, why do you believe the probability that hallucinations as a problem will be solved (at least to the point that they are rare and mild enough not to matter) is literally 0? Do you think that the existence of fanatical AI zealots makes it less likely?
Okay, so by your logic the probability of literally everything is 1. That's absurd and that's not how Laplace’s law of succession is supposed to be applied. The point I'm trying to make is that some things are literally impossible, you can't just hand-wave that!
And I'm not saying that solving hallucinations is impossible! What I'm saying that it could be impossible and am criticizing your blind faith in progress because you just believe the probability is literally 1. I can't say, for sure, that it's impossible. At the same time you can't say, for sure, that it is possible. You can't just assume the problem will inevitably be fixed, otherwise you've talked yourself into a cult.
I'm not saying the probability of literally everything is 1. I am saying nonzero. 0.00003 is not 1 nor 0.
I am not assuming the problem will inevitably be fixed. I think 0.5 is a reasonable p for most.
You do not know that it is nonzero, that's just an assumption you made up.
Also, Laplace's law of succession necessarily implies that, over an infinite number of attempts and as long as there is a possibility of success, the probability that the next attempt results in success approaches 1.
