Fresh example:

I described a problem on UI level. LLM suggested the Ramer-Douglas-Peucker algorithm to solve it, which I have never heard about before. It implemented it. Works perfectly. It is 40 lines of code (of which I only really need to review the function signature, and note the fact that it's a recursive bisection algorithm). I would have spent a very long trying to figure out what to do here otherwise and the LLM handed me the solution.
