I found this short excerpt of Steve's interview in 2010 D8, a time when he was already publicly and visibly known to be quite ill. During the Q&A session, a member of the audience asked Steve if he would add anything to his famous speech in Standford; the question struck him with deep emotions that was rather unexpected from a figure like him.
It is quite remarkable that, knowing what was happening to him, he was able to remain so composed yet candid at the same time, expressing himself ever so eloquently and poetically. I browsed through his biography for his state of the mind then that may explain how he could do so, to no avail (I haven't given it a careful read). I am sure a throughout read of this book would allude a lot more about his way thinking.
