The goal isn’t to be more or less useful than a person. It’s to expand the capabilities of computers. And computers are exceptionally good at mathematics tasks already. Why do we care if LLMs are good at things that are already exceptionally well done with computers? The point is they’re exceptionally good at things computers to date have been exceptionally bad at. The rest is weird goalpost moving noise - I wouldn’t use ChatGPT to solve a quadratic equation, I would use Mathematica, or any number of numeric libraries and runtimes. But I challenge you to get Mathematica to summarize a book, carry on a conversation, or even call an api based on natural human language without a rigorous specification apriori. These are holy grails of NLP, which is a capability that is enhancing of the existing capabilities offered by computing technologies today.
