That's far too reductive. The law is abstract, and still needs to be interpreted and prudentially applied to specific situations, and you cannot capture all of that in the law a priori. Furthermore, having a computer crunch through a bunch of predicates is easy compared to getting the facts expressed in a form that is crunchable. So for specific and narrow applications where such representations are not costly to produce or already exist, such an application of computational law is feasible. But broadly? No.

And then there's the distinction between lex and ius that I think needs to be considered in this context.
