There's a large continuum between great and crap, and it sounds like you've placed a rather high bar to even consider using it.

I don't like BASH scripting. I wanted to automate a certain task and dump it in a justfile for convenient reference.

Learning BASH scripting would be a poor use of my time - I didn't value the knowledge I would gain.

Using Google to piece together everything I needed would have been very painful. Painful enough that I simply didn't bother in the past.

Asking an LLM solved the problem for me. It took about 6 iterations, because I had somewhat underspecified and the scripts it returned, while correct, had side effects I didn't like.

But even though it took several iterations it was infinitely more satisfying than the other options. Every time it failed I would explain to it what went wrong and it would amend the script.

It's like having an employee do the work for me, but much much cheaper.

That's the power of LLMs. They enable me to do things that just weren't worth the time in the past.

Would I use it for my main programming work? No. But does it increase my productivity? Definitely.
