Why not mow a lawn with a sledgehammer? It removed grass that was overgrown. And it was cheaper than a lawnmower.

Your analogy doesn't work.

This patient saw 6 doctors over 2 years and they all misdiagnosed them. They were taking incredibly strong medication for the wrong diagnosis.

GPT3 in 30 seconds gave 10 diagnosis and a doctor looked up the ones they didn't know. Saw one that fit, did the confirmation test, and the patient got the surgery needed.

Cheaper and better.
