Interesting. Probably won't work for harder queries, but would be a good tool to make simpler queries, or parts of harder ones.
my opinion: probably will work for harder queries, because GPT is a form of general intelligence. (At least ChatGPT is. It is a much more advanced form of intelligence than davinci-003, which the poster used.)
You can trick it into working more-or-less correctly on simple sets and simple tasks, but in the wrong run it will be more wrong than correct.
