Well, there's a problem that needs a solution. Plus, a government contract. I wonder if anyone can come up with a LLM for simple tax issues.

I can't think of a worse use for an LLM...
You really under-estimate how googleable 97% of customer service calls are. The average person does not make any attempt to solve their own problems before calling customer support. That's just life.

Yes in an ideal world we would have a live customer support representative for every function in every facet of society, but there are a limited number of human beings available for such things, and this is a pretty reasonable place to do a first triage using a LLM for very simple questions.

One of the most observed weaknesses of LLMs is that they have no clue when they're dealing with a difficult problem. There's no doubt that throwing an LLM at the problem would likely fix many simple issues. The question is whether or not it can accurately triage a difficult issue, which is a task they tend to struggle with.

When accuracy matters, answering a question incorrectly puts a person in an even worse situation than simply failing to answer the question.

ChatGPT is not trained to "escalate" an issue because there's nobody to escalate to. You can get this to happen pretty reliably via prompting, and with even light retraining basically 100%.

And here's the thing: most front-line customer service is also clueless about difficult problems. The IRS cannot pull 10,000 seasonal experts on the line, they are going to hire barely-trained part-time accountants who also flub hard questions.

But human brains have a more developed and reliable means of expressing uncertainty, which is still a challenge for LLMs.

e.g. part-time front-line customer service will prefix a statement with "uhhh..." if they don't actually know what they're talking about, even if they do have trouble answering accurately.

You can literally prompt GPT4 "Prefix a statement with uhhhh if you don't know what you are talking about" and get similar behavior.

It's one of the reasons why I stopped joining facebook groups. Every day the same ^%$#^#%$ post by a [adjective] [derogatory term] who couldn't be bothered to use Google / Bing / ect.
When all you have is a hammer, everything becomes a nail I guess.
It would have to be able to fix your records in the IRS database, not just give you advice from the FAQ like most LLM support bots. Which could be awesome, but it'd have to be robust against prompt injection attacks and other bamboozlement.
