common sense has the misfortune of being less "common" than we would all like it to be. because some breathless hucksters are overpromising and underdelivering in the present, we may as well throw out the baby, the bath water, and the bath tub itself! who even wants computers to think like humans and automate jobs that no human would want to do? don't you appreciate the self-worth that comes from menial labor? i don't even get why we use tractors to farm when we have perfectly good beasts of burden to do the same labor!
