It's a fair point, but plenty of humans don't actually have the background to know all that stuff either. If you told a eight-year-old that Bush spent millions fighting his father's war, the kid would know that Bush was a person not a shrubbery, but that's about it. The child could read and understand every word of the sentence, but she'd lack all the same context the computer does.
