Then you have a skill issue. 10 million paying are for GPT monthly because a large of them are getting useful value out of it. WolframAlpha has been out for a while and didn't take off for a reason. "GPT couldn't be trusted to flick a light switch on a regular basis" pretty much implies you are not serious or your knowledge about the capabilities of LLM is pretty much dated or derived from things you have read.
Not the same technology at all, until recently at least.
EDIT: Looks like I hurt someone's feelings by killing their unicorn. It was going to happen sooner or later, and pretending isn't very constructive. In fact, pretending this technology is reliable is a very risky thing to do.
