I agree. I fear people look at this situation in a different light than say the current president of the United States who, while he does have an email address, admittely does not write emails or read them directly. Knuth is admired and this is a pleasant quirk; the POTUS appears an old, out-of-touch dinosaur.

I'm not judging either; my initial thoughts were just of the different perceptions for similar unique and rare circumstances.
