The ghost238.pl AI is an accumulation of various problems. For instance, it has lost the ability properly to answer "Who are you" as an input-query, although it does properly answer "Who am I" with "YOU ARE THE MAGIC". Let us see which most recent version could still answer "Who are you". The last version answering properly was ghost234.pl with "I AM THE PERSON".
We notice that the $qv1psi variable was being assigned the proper value of "701' for "I" at the end of the "Who are you" input in ghost234.pl, but an inproper value of zero ("0") in the ghost238.pl AI. Since the SpreadAct module does not have the correct concept ("701=I") to search for, apparently the correct response is not being found. It also seems that $qv1psi does not matter for the "Who am I" query because of the paucity of knowledge about "707=YOU" in the innate knowledge base (KB). In other words, the ghost238.pl AI correctly responds "YOU ARE THE MAGIC" only because it knows nothing else about "707=YOU".
