As a fellow below average programmer I have used them for that, but it feels like a fairly minor improvement over searching stack overflow, but that is definitely an area where it is a time saver, thanks for the example.

I must be more below average than you because it's a huge improvement for me over stack overflow.

I'm doing mostly scripts (some Python but mostly Google Apps Scripts) to automate processes at a digital marketing agency. As long as I can clearly explain how our business works and what I'm trying to accomplish I'm getting working first drafts of things that would take me hours to write (a way worse version of) in 30-40 minutes – and 25-35 minutes of that is writing the prompt/documenting the automation I want made.

It's really been amazing for me.
