I've been snarky for this entire conversation - I find advocacy of death extremely irritating - but I am not just snarky by any means. The laws of physics as now understood allow no such thing, and even the author of the document to which you refer - a master of wishful thinking - now regards it as obsolete and wrong. And the point still holds - you cannot benefit today the way you could in a post-em world. If you're prepared to throw away billions of years of life as a precaution against the possibility of billions of years of torture, you should be prepared to throw away decades of life as a precaution against the possibility of decades of torture. If you aren't prepared to do the latter, you should reconsider the former.
