I personally see the LLM as a (considerably better) alternative to StackOverflow. I ask it questions, and it immediately has answers for my exact questions. Most often I then write my own code based on the answer. Sometimes I have the LLM generate functions that I can use in my code, but I always make sure to fully understand how it works before copy-pasting it into my codebase.
But sometimes I wonder if pushing a +400.000 lines PR to an open-source project in a programming language that I don't understand is more beneficial to my career than being honest and quality-driven. In the same way that YoE takes precedence over actual skill in hiring at most companies.
