The other day I asked AI to one-shot an implementation of hyperbolic trig functions for double-double floats.

I provided a repo (mine) that already implemented double-double arithmetic, trigonometry, and logarithms/exponentials, with plenty of tests.

It produced something that looked this good. It had tests, it followed the style of the existing code base, etc. But it was full of shit and outright lies.

After I reviewed it to fix deficiencies, I don't think there was anything left of the original.

I had much more success the previous week using an AI to rubber duck the algorithms to implement trig.

I am incredibly sceptical that just adding more loops — and less critical thinking/review — to brute force through a solution, is a good idea.
