You would probably realize pretty soon if you try writing anything meaningful with Prolog. In my experience Prolog is conceptually the coolest, but practically the worst when trying to get anything done. Basically, writing a program in Prolog is like solving a puzzle. Nobody wants to solve an additional "puzzle" on top of their already existing problem they set out to solve by programming. (Unless they're doing it for fun)
