The OP and the farmer are people who coded in the past. There can be a big difference between someone who understands how computers and code work generally, and someone who doesn't.

I was a software engineer up till about 8 years ago. I still dabbled in scripts here and there for things I needed since then. LLMs have proved hugely useful for me to do a wide variety of things that wouldn't have been worth bothering with before. The biggest barrier that LLMs overcome for me is being able to quickly find and adapt to different tools, libraries, languages, etc. But it does help immensely to understand how software works to some degree for being able to approach the problem in the first place. I think the two factors multiply together.

I imagine if I want to I could get back into real software engineering much easier and faster than I could have a few years ago, because I still understand how things work fundamentally, I'm just out of date on what's changed in libraries and systems and languages in the last 8 years.

It's also useful for working with spreadsheets and databases.

Anyway I don't mean to shill for LLMs, I hate where this all is taking civilization in general but I'll still use it where it helps me accomplish things I do value.
