"Now Mr. Jobs always was a free thinker, a strong believer in spirituality, a vegetarian and a known skeptic of conventional medicine. He chose to reject conventional medicine altogether. He's not alone in that. We come across many people like this and we all know someone in our midst that uses homeopathy or has this known fear of anything "chemical" (to those I always say that everything is chemical, if you think dihydrogen oxide sounds scary you should stop drinking water). Individual freedom of thought and choice is a cornerstone of our modern society and the medical world makes no exception."
Your argument seems ideological to me. I certainly agree, this is how things should work, but I would see evidence before believing that the average medical professional really does learn from their mistakes.
