Actually, a computer can do a great job of anything you can think of. It has a
problem if something comes up that nobody thought of -- like the Sioux City
accident, or if it doesn't have certain information -- like the closed airport
used by the "Gimli Glider." And, of course, it can't handle failure of itself
very well.
