I work with java and do a lot of integration, but a looot of my effort goes into exploring and hacking away some limitations of a test system, and doing myself things that would take a lot of time if I had to ask the proper admins. I had a problem where I was mocking a test system (for performance testing of my app) and I realized the mocked system was doing an externalUserId to internalUserId mapping. Usually that would have been a game stopper, but instead I did a slow run, asked Chat GPT to write code that reads data from a topic and eventually create a CSV of 50k user mappings; it would have taken me at least half a day to do that, and Chat GPT allowed me to do it in 15 minutes. While very little code went into my app, Chat GPT did write a lot of disposable code that did help me a lot.
