Cargo-Cult programming is already happening at a not-insignificant scale due to the vast amount of sample code/tutorial/Q&A online. There could be lots of nuances in that snippet you just copied from a SO comment, which "just works". GPT-3 based tools could help you generate a working (or barely working) sample fairly easily. But the decision to just ship that code as is, or to understand it and tune it for your specific needs still mostly depends on the developer.
