How are you assigning the probability here? Some of his arguments (which are actually standard pro-atheism arguments) seem to be based on life extension, i.e. science leads to longer lifespans therefore it is superior to religion. His dismissal of cryonics is well known (and deeply tragic in my opinion), but he has not to my knowledge taken the position that everyone should, morally or philosophically, have a duty to die by the time they hit age 120 or so, or that there is such a thing as a "natural lifespan" towards which we are obliged.
