alt Hacker NewsThe frustrating part about an LLM is at a fundamental level it's designed to do the wrong thing, it's designed to provide an answer for things it can't do, e.g. one argument I've been in recently at work is someone using it to summarise numerical data. They've a raw data spreadsheet they're putting into ChatGPT and asking it to produce a report in a particular style. So the LLM is doing its job, predicting the tokens to emit, and not actually doing mathematical analysis of the underlying data.
I had a team proudly show me how they were feeding their dashboard data into an LLM to predict growth needs, instead of doing basic linear regression or any number of pre-existing basic statistical analysis. The part that depressed me the most on that was it was a bunch of engineers that did it, the people you'd most hope would understand what an LLM is/does.

For numerical work, there’s no reason to assume the computation is happening in the LLM. All frontier models could handily write a Python script to do linear regression then report the result, so the quality of the responses here depends entirely on the prompt + harness.
These days I wouldn't be surprised if the models are smart enough to get the analysis correct.
However sometimes I think that AI use shows a revealed preference around things. In this case, the actual data just ... maybe never mattered to them at all? People wanted a shiny chart and they got a shiny chart.
Either chatgpt or claude are building scripts to do those and has been for a few months at least now.
I'm building a little side business with LLMs doing 90%+ of the work, and this includes numerical analysis of revenue to figure out where to direct effort.
Today the problem you're mentioning is easily avoided if you are aware by ensuring you direct the agents to build tools for anything deterministic.
Every week "we" (myself and Claude) start by analysing revenue from the previous week. Claude will do some manual proposals but they will be based on analysis done by a deterministic script. It will then run workflows that are increasingly calling deterministic scripts - every week another few decision points the agent used to do (and that I had to then manually vet) gets replaced by deterministic scripts.
It is what allows what is a very low margin opportunity to work - it is scaling with the total amount of manual labour and total token use remaining near constant. It's an opportunity that I won't go into much detail about because the margins are thin and the moat narrow and it's basically only viable because of this approach of setting a tiny budget where ~1/3 of it or so is dedicated to systematically eliminating manual and LLM work from the process.
Even so, I expect the opportunity to actually extract profit from it is going to be short-lived - the moat will eventually evaporate if LLMs keep getting cheaper and better in favour of people "just" asking an LLM to do the whole thing end to end.
So on one hand I agree with you - there are lots of things that'd be better automated with scripts, and where there might well always continue to be efficiencies you can extract by turning things into deterministic scripts instead. On the other hand, LLMs are already so cheap for a lot of things that it increasingly doesn't matter, and good enough that where it does matter they will increasingly also just write tools themselves if you ask them and sometimes - and likely increasingly so over time - without even being asked.
