I mean, the computer industry promises nothing. Did you ever read a shrink-wrapped license agreement? You should read one. It basically says, if this product deliberately kills your children, and we knew it would, and we decided not to tell you because it might harm sales, we're not liable. I mean, it says stuff like that. They're absurd documents. You have no rights.

… if anyone thinks they can get an accurate picture of anyplace on the planet by reading news reports, they're sadly mistaken.
