Not to defend a joke app, but I have worked in “serious” production systems that for all intents and purposes were impossible to recreate bugs in to debug. They took data from so many outside sources that the “state” of the software could not be easily replicated at a later time. Random microservice failures littered the logs and you could never tell if one of them was responsible for the final error.
Again, not saying GPT backend is better but I can definitely see use-cases where it could power DB search as a fall-through condition. Kind of like the standard 404 error - did you mean…?
