You were doing pretty well there, then dove back into the ad hominem. Who he is as a person is entirely irrelevant, if you want to criticise the letter then criticise the letter, not the man.
I am talking about my emotions, yes. All I can say, if you don't like it, is that I am sorry. But I don't believe one can have an entirely objective discussion on this topic which will arrive at an incontrovertible answer. Most tech inclined people (e.g. HN readership) are positively biased towards the space program. I am not, despite the fact that I fit the profile. I think it's science done for the wrong reasons. In addition, I don't like this guy and I expect to disagree with him and I can't change that.
