People who aren't on board with llms as the biggest driver of growth since internet search were the type of people who still thought the yellow pages were safe from Google in 2004.
I was writing a lot of rather complex augmented matrices.
Instead of having to manually type them in with all the formatting done by hand I literally gave ChatGPT a python nested list and told it what to subscript, what to bold, etc.
In previous papers I have done this by hand if there's only a few matrices that I need to show, or by writing a script to auto-generate them in whatever format I need if there will be many.
This time I just talked to a chat bot and got it working in minutes.
Then it turns out I made a mistake at the start. The fix was just to tell it what the error was and propagate the changes. It did that flawlessly.
Using an LLM to reformat/restructure your matrix data makes sense to me and this was the missing detail from your original post.
I would be too paranoid about hallucinations and opt for a script still, but that might just be personal preference.
