Software bugs and AI

Currently there is a lot of interest in using AI to help us find and fix software bugs. On the other hand AI software may, itself, be more prone to bugs as compared to more conventional  software. If we don't fully understand what intelligence is or how it works how can we know if our AI software is buggy? There are even those who believe that human intelligence is, itself, a kludge and the resulting spaghetti code needed to model it is likely to be buggy. Most AI researchers find that it is harder to debug AI code. Its harder still to debug the software when robots are involved.
