Gadol, not that simple. Machine learning works well (or at least with predictable performance) in a “closed world” (olam satum?). When events change, or even just their probabilistic distribution, then you would need contemporary poskim to re-train the system. This is what parsha Shoftim teaches – go get training data from shoftim of your generation. So, here (computer) science and Torah are in full agreement.
The problem would be that when most of psak will be given by AI, how do we ensure that new generation poskim will be ready to step in? Same as how do we keep pilots to be ready to step into a complicated landing when they are sleeping through the flight most of the time.
