I'm left with a feeling of ambivalence. I feel bad that he couldn't enjoy the fruits of his labor by retiring and spending time with his family or whatever other interests he had. At the same time, I know that he wouldn't have had it any other way.
He recognized his gift and shared it with all of us. The experiences when using his products and the emotions when hearing him speak. I feel blessed just to have been a witness to such a human's life.
