Helped: Generating disposable code for data mapping and CSV creation.
… 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.
