It really isn't. GPT-4 is certainly an improvement over previous language models, but when I vaingloriously gave it the questions from favourite self-answers on StackOverflow, only one completion was immediately correct. The remainder were variously suboptimal, poorly crafted, overdesigned, incomplete, or downright wrong, requiring multiple re-prompts to coax into usable condition. The they were all syntactically valid but tended to misconstrue the semantics and underestimate the capabilities of the programming environments concerned. Try it with your own, but to me it's more like coaching a bright but inexperienced junior developer with the "confidently incorrect" trait.
