Not saying there aren't places here where you can software develop yourself to burnout death, but that really becomes a personal choice at that point. 80+ hour weeks are for the crazy ones. Sometimes it's the beautiful passionate crazies, and something amazing happens. I don't want to play down the results[0], but it's a gamble you play with your own health, life and well-being, it's a choice and one's own responsibility. You can't stop them, but you can make sure they may not hurt themselves too much.
[0] Actually, most examples I know of this are from areas completely outside software/computers, superheroes giving themselves for social/societal causes--but I wouldn't exclude "our" line of work per se.
