Not sure about what you mean with 'oblivious' here, but Jobs' opening email is indeed flawless--taking into consideration that Apple's CEO allocated some time amidst the frenzy to write it: no trivialities, no redundancies, no chance of not being taken seriously or of being misunderstood.

I wonder how much mental debt would be eliminated if all of the world's emails were that clear. Note that, in essence, we're talking about the major means of human communication--and thus information exchange--at least in the tech industry and academia. Pretty important and impactful stuff.
