We tolerate fewer faults from our computers because the underlying system is not complex enough to prevent those faults from affecting us in large ways. As you say, a small failing in the human body doesn't render the entire organism inert and useless; no, we can adapt our behavior during healing and move on. When a small fault occurs in your computer, it tends to have disastrous effects. We will tolerate faults in our computer systems when then faults don't cost us our homework, our jobs, or our lives. And complexity is the only way to making that happen. I, for one, welcome our new chaos-wielding overlord!
