Yes Steve, you are right, that is pretty close to the ‘secret sauce’. And yet, don’t humans do about the same thing when they answer similar questions?
I taught the AI that some symbols (words) represent countable units. Countable units can be compared, and can have a; =,>,< relationship. When that relationship deals with age, the smallest units are youngest and oldest are the largest.
If you believe this is thinking or not is much more based on your philosophy than absolute truth. We may never know everything that goes into a human thought, and all machines might ever do is emulate the process.
