The 'inverse square root' carmack trick is hardly trivial.

so luckily no one owns the idea that you can use both newtons method, and floating point bit-hacking, to produce a good estimate of a square root.

So if a similarly non-trivial piece of code was in a non-public-domain codebase and copilot copied that wholesale, then you'd have a problem with it?
