Even if this were all true, it points to a fundamental risk of using LLM's for important tasks, which is that it is not at all clear to a user that this prompt would cause a problem. The LLM doesn't say "I'm sorry Dave, I just can't do that", it just complies with it and gets the wrong answer.

You can always make excuses for the LLM afterwards, but software with hidden risks like this would not be considered good or reliable in any other context.

While LLMs have incredible potential, and are even downright useful in their current format, they have the rather nasty tendency to confidently present bullshit that passes the smell test for most people. When it's wrong, it's not just wrong, by design, it's wrong but sounds plausible. Considering most people with subject matter expertise aren't going to consult such a bot for their own areas of expertise, that means most people will not be able to detect it intuitively.

Good example: I sunk probably an hour into trying to get Gemini Advanced to help me integrate it with a personal Google Calendar account. I kept asking it things and going crazy because nothing lined up with the way things worked. Finally, it referred to itself as Bard and I realized it was giving me information for a different product. As soon as I asked "are you giving me instructions for Gemini Advanced or Bard?" it was like "OH LOL WOOPS!! YOU GOT ME BRO! XD I CAN'T DO ANY OF THAT! LOL." Which, honestly, is great. Being able to evaluate its answers to realize it's wrong is really neat. Unfortunately, it was neat too late and too manually to stop me from wasting a ton of time.

I have decades of experience working in software-- imagine some rando that didn't know what the hell Bard was or even imagine this thing with "Advanced" in the name couldn't even distinguish between its own and other products' documentation.

Did it evaluate its answers, or did your expression of doubt cause the eager-to-please language model to switch from "generate (wrong) instructions because that's what the user asked for" to "acknowledge an error because that's what the user asked for"?

How many times have we seen "Oops, you're right! 2 + 2 is actually 5! I apologize for saying it was 4 earlier!"

I suppose whether or not these things evaluate anything at all depends on your perspective, but as soon as I asked if it was giving me the correct information, it did actually give me useful information after that without further prompting.

People really need to stop trying to model an LLM as some kind of magical software component: it all makes a lot more sense if you model it as an under-performing poorly-aligned employee; so like, maybe a distracted kid working for peanuts at your store. You wouldn't trust them to with all of your money and you wouldn't trust them to do a lot of math--if they had to be in charge of checkout, you'd make sure they are only given a point-of-sale terminal and their main job was to, at best, scan the barcodes and compare the total--and yet there are tasks you can imagine handing to them that you'd never give to a robot or computer even though they get it wrong a lot, as not all tasks need to be handled perfectly, they still understand extremely fuzzy tasks, and they are probably cheaper than a qualified adult (certainly cheaper than one who is being paid enough to "give a shit" and pay enough attention to not let you get robbed or even put themselves at some risk for you).

You have a point...

I once gave a 10-dollar bill to a young man serving at the cashier at a store, and he gave me 14 dollars back as a change. I pointed out that this made no sense. He bent down, looked closer at the screen of his machine, and said "Nope, 14 dollars, no mistake". I asked him if he thought I gave him 20. He said no, and even shown me the 10-dollar bill I just gave him. At that point I just gave up and took the money.

Now that I think about it, there was an eerie similarity between this conversation and some of the dialogues I had with LLMs...
