Do you not debug, optimize, analyze ...? Copilot is especially valuable for throwaway (or nearly throwaway) log parsing/analysis, for example.

I do, but I have all the software I need for that. I may use LLMs in that context, but for the actual analysis, not for generating one-off tools.

That used to be the case with me too before LLMs.

It was because writing one off tools took time and you needed it to do more for it to be worth the time.

Now a lot more are getting written because it takes a lot less effort. :-)

It just depends on the environment. Some areas get to experiment with different approaches more than others. On one extreme if I was writing yet another crud app, it's unlikely is need any such tools. On the other, when dealing with data processing/visualisation/ml, it's small experimental tools all over the place.
