One of the older philosophical problems of AI has been that the field has been defined by problems that stop being "AI problems" as soon as a solution is discovered. So, if those problems weren't AI problems after all, then what exactly is AI?
One solution to this conundrum is to simply say that AI research is just that, a research process. There are no inherently AI problems and AI research is just a process by which we uncover solutions to previously intractable problems.
