Did any of the commenters read the slideshow? Heroism is bad when it covers systemic problems. Heroes are great -- SREs who rise to the occasion to prevent horrors are appropriately rewarded and congratulated for their work. But when a product relies upon heroes to continue operating, you are in a dangerous situation. That's how major outages occur; the hero goes on vacation or decides to let it break this time and the cascade of failures causes huge amounts of damage, where letting the system break much earlier would have made it clear to the development team that there is a major gap in the intrinsic reliability of the system.
