I agree with that conclusion, use what you started with and keep improving it. The only thing AI has is the first initial, "artificial" but no intelligence.
Interestingly enough, it is easy enough to emulate what the current AI happens to be but on a far smaller scale. Start with a simple tree, keep adding nodes to it in both width and depth with each node storing data and to increase its range, make it possible for each node to link to any other node to get data from that location. With new ideas (pseudo learning) make it possible to create new trees that have the same capacities as the original tree of being able to link to any other node and you are on you way to creating a pseudo intelligent piece of software.
The difference between a tiny project like this and what is being peddled as AI is only the scale available to search engines, a truly massive volume of links to many subjects.
