> Yep having the same experience right now with some curve/spline tessellation into triangle strips. There are many degenerate edge cases and when you ask the "ai" to handle one it breaks something else etc. Makes me think that if I had just hand coded it myself I would intimately know the code and get it working faster than prompting. Gah.

It gets so much worse. At some point you start hitting edge cases where there is no clear right answer and you have to come up with a kernel wide coherent approach to things like 1ulp differences. Parasolid is full of decades of kludges on top of kludges and giant switch statements trying to preserve backwards compatibility as they explored the space.
