If somebody asks a question on Stackoverflow, it is unlikely that a human who does not know the answer will take time out of their day to completely fabricate a plausible sounding answer.

Have you ever heard of Dunning Kruger effect?

There's a reason why there are upvotes, solution and third party edit system in StackOverflow - people will spend time to write their "hallucinations" very confidently.

Gravity isn't 9.8m/s/s across the universe. If you're at higher or lower elevations (or outside the Earth's gravitational pull entirely), the acceleration will be different.

Their point was the 9.8 model is good enough for most things on Earth, the model doesn't need to be perfect across the universe to be useful.

g(lower case) is literally gravitational force of Earth at surface level. It's universally true, as there's only one Earth in this universe.

G is the gravitational constant which is also universally true(erm... to the best of our knowledge), g is calculated using gravitational constant.

I asked Gemini the other day to research and summarise the pinout configuration for CANbus outputs on a list of hardware products, and to provide references for each. It came back with a table summarising pin outs for each of the eight products, and a URL reference for each.

Of the 8, 3 were wrong, and the references contained no information about pin outs whatsoever.

That kind of hallucination is, to me, entirely different than what a human researcher would ever do. They would say “for these three I couldn’t find pinouts” or perhaps misread a document and mix up pinouts from one model for another.. they wouldn’t make up pinouts and reference a document that had no such information in it.

Of course humans also imagine things, misremember etc, but what the LLMs are doing is something entirely different, is it not?

Newer models can run a search and summarize the pages. They're becoming just a faster way of doing research, but they're still not as good as humans.

Thanks for your input - great to hear from someone involved that this is the direction of travel.

I remain highly skeptical of this idea that it will replace anyone - the biggest danger I see is people falling for the illusion. That the thing is intrinsically smart when it’s not - it can be highly useful in the hands of disciplined people who know a particular area well and augment their productivity no doubt. Because the way we humans come up with ideas and so on is highly complex. Personally my ideas come out of nowhere and mostly are derived from intuition that can only be expressed in logical statements ex-post.

Is intuition really that different than LLM having little knowledge about something? It's just responding with the most likely sequence of tokens using the most adjacent information to the topic... just like your intuition.

I’m with the people pushing back on the “confidence scores” framing, but I think the deeper issue is that we’re still stuck in the wrong mental model.

It’s tempting to think of a language model as a shallow search engine that happens to output text, but that metaphor doesn’t actually match what’s happening under the hood. A model doesn’t “know” facts or measure uncertainty in a Bayesian sense. All it really does is traverse a high‑dimensional statistical manifold of language usage, trying to produce the most plausible continuation.

That’s why a confidence number that looks sensible can still be as made up as the underlying output, because both are just sequences of tokens tied to trained patterns, not anchored truth values. If you want truth, you want something that couples probability distributions to real world evidence sources and flags when it doesn’t have enough grounding to answer, ideally with explicit uncertainty, not hand‑waviness.

People talk about hallucination like it’s a bug that can be patched at the surface level. I think it’s actually a feature of the architecture we’re using: generating plausible continuations by design. You have to change the shape of the model or augment it with tooling that directly references verified knowledge sources before you get reliability that matters.

I mean... That is exactly how our memory works. So in a sense, the factually incorrect information coming from LLM is as reliable as someone telling you things from memory.

> No standard has ever been developed using money obtained by selling copies of the standard.

unfortunately there are examples in the Telecom world

JAlexoid · 4 days ago

Most of the development costs are recouped through licenses on the base-stations and somewhat on the very low patent licenses per chip/device, not the price of access to the standard.

Back to the the HDMI standard, the licensing fee has already been paid by the hardware manufacturer. Restricting software is unnecessary, as the patent license fees have already been collected on the device.

We call them "LINO"s.

JAlexoid · 18 days ago

Or... You know... We also like watching one giant corporation that benefits from distinctly authoritarian policies get wrecked by another authoritarian entity to the benefit of better competition in the market.

But apparently unless you're a suckup to the authoritarian entity that you like is now a LINO.

That is not what distribution means.

I am allowed to splice up my personal copies of videos.

JAlexoid · 18 days ago

You are allowed to splice it up, when you have a legally acquired personal copy.

But in this case you don't have one in the first place.
