You are actually getting overly philosophical. The reason is that a step of chatbot training is to fine tune the base model to less frequently respond with non answers. I have not read the article, but the answer is: Because they are specifically built not to. Its like asking why so few salesmen end a call with "yeah it seems our product is not the right solution for you"

Only person who understands this is a style choice and not a deep limitation of the robot condition.

If a politician has non-answers for difficult questions, does that mean they aren't conscious? If a student writes crap for a test question, aiming for partial marks, were they raised wrong?
