Poorly understood? how convenient...
LLMs are vectorial databases with losses that index statistically filled data, which uses a text interface to query such statistically filled data. The output is a string concatenation (statistically concatenated bit by bit).
When the LLMs are queried (prompted), you can get random mixed data as output, ERRORS, due to undesired indexes getting closer at one point while the string was being concatenated for the output, what affects the rest of the indexed content that will be concatenated.
It is intrinsic to this tech. The larger the context, the greater the probability of get mixed data. And if the provider lowers the precision of those indexes -in order to decrease hardware resources and energy consumption- such probability increases to the point where those errors are granted.
Even knowing that the queries can return wrong/mixed data in the responses, errors, the companies developing this, decided to introduce a new product, that connects such LLMs outputs to the command console, latter connected to internet, raw 'eval' running commands from such outputs witch obviously can contain whatever mixed random. Then we started to hear "oh, it deleted my directory", etc, and it seems the next one will be "a missile killed my wife", because it is a text concatenation engine with errors.
To name it "hallucination" is an euphemism... those are errors, and they are granted to happen at one moment. If they do not know this, then they ate too much marketing without doing their job, or it was a convenient contract for the pocket$ of someone.

Yes, and that statistically filled data is insanely useful. It remains true that it's a relatively poorly understood how this can be applied in various scenarios and what processes are needed to ensure robust results (or quantify the uncertainty).

LLMs generate text output that appears to be useful, but regularly is not. They're alleged to be a substantial boost to writing code, but that verdict seems to be in dispute. They can generate custom mediocre prose at scale, but that seems to be of ultimately limited utility (although it may be a godsend for propagandists).
We're coming up on the 4th anniversary of ChatGPT's release. And while I get that revolutionary technologies can take a while to mature, the Wright Brothers and Goddard weren't preaching imminent societal transformation by the end to the decade from the rooftops, either. (And that's before we get into the how they got there - getting to ignore laws and steal whatever they wanted might be insanely useful to a lot of people.)

I can see that some people can make some use of them. (This is true of almost everything.) Whether or not that usefulness is worthwhile overall, whether it is a net good, or even ethical is a different question. But insanely useful?
Computers are insanely useful. So are engines. Water. Sunlight. Electricity. Grain and bread. Writing. Printing. And I don't feel bad making those sorts of comparisons, because that's the level of impact LLMs' advocates are promising. But it's not what we have.
What I would consider sufficient evidence for insanely useful? Reliably replace a human in prolonged, arbitrary, detailed interaction, without any inhuman screwups.
