Run for your lives-the computers are invading. Awesomely powerful computers tackling ever more important tasks with awkward, old-fashioned interfaces. As these machines leak into every corner of our lives, they will annoy us, infuriate us, and even kill a few of us. In turn, we will be tempted to kill our computers, but we won't dare because we are already utterly, irreversibly dependent on these hopeful monsters that make modern life possible.

Alan CooperTo our human minds, computers behave less like rocks and trees than they do like humans, so we unconsciously treat them like people.... In other words, humans have special instincts that tell them how to behave around other sentient beings, and as soon as any object exhibits sufficient cognitive function, those instincts kick in and we react as though we were interacting with another sentient human being.
