Rated Against ChatGPT by Non-Tech Managers

One word.

Run

Any company where non tech managers want to say gpt can do that in 5 minutes doesn't understand the small and subtle ways gpt will misinterpret making things very messy very fast.

In toy problem scenarios gpt does pretty darn well... Because those are toys with obvious starts and ends. Gpt is useful for people who already know the answer but want to use gpt to type it up for them.

In any case, reasons aside... If your manager is hostile to seeing you as valuable leave. There's no way to improve things in that situation.
