Whoever agrees with that blog post doesn't belong in medicine, the purpose of which is to ameliorate disease. The limits of medical technology aside, the author is trivializing patients' suffering and the potential loss of everything that makes life worth living, if not implying that they somehow deserve to suffer or that suffering should be accepted as the default state of human life. If a disease ruins your life, knowing that there are other people who also suffer will not help you. It's easy to mouth off when you're healthy, but when it's your own life that's been devastated, you'll come to appreciate how utterly worthless doctors like that author are.
