ChatGPT is ALWAYS doing stuff like this to me. Suggest code that doesn't compile, suggest SIMD instructions that don't exist, reiterate on incorrect answers with the exact same answer, etc. Granted I use ChatGPT 3.5.
well that's one way to make code faster, just require the underlying hardware to compute things for you
But every time it gave me a very sensible solution.. Usually not something that worked right out of the box but never something totally stupid.
