Because human neural networks don't learn, they are calibrated. Calibration requires bandwidth and time. The neural networks literally anneal calibration into them selves physically. It's as much work, if not more, than going to the gymn and picking up the heaviest weights and lifting. We don't have pain circuitry in our brains to tell us that it hurts, but we do know that there is a phenomenon of "yawning" that all students have when they are sat in a classroom and bombarded with new information. I do it as well, I was not aware of it until someone pointed me to that info. That isn't the only problem. The real problem is that your assumption is that you, the person the label the name is real. You don't exist. You, and I, the persons the labels the names, are thin pieces of software existing in the pre-frontal cortex. We are the puppets of our silent brain, our job is to justify to our selves our belief systems acquired through the annealing process our neural networks do on a regular basis. The other job that we perfom, us the person the label, is to act as a firewall between the world and the silent brain sitting behind the pre-frontal cortex. What you want is irrelevant. What you believe doesn't matter. All of that is decided for you silently by your neural networks sitting behind the pre-frontal cortext self calibrating in silence without you being aware of it. Or, to put it another way, you can't walk up to a person and just give them new information, there isn't enough bandwidth available to have that be effective. The best you can do is give them directions and even then they have to be looking for directions otherwise they won't listen.
