The part about "hero culture" that needs to be said more often is that you need to reward the teams that have boring and predictable production environments rather than the ones who put in heroic efforts to keep unpredictable and blowup-prone production environments working.

I've seen way too many orgs be appreciative of employees that give over-the-top efforts without appreciating those that plan, test and deliver in a fashion that makes over-the-top efforts unnecessary.

Not sure if that was part of his spoken presentation, but it didn't make into his slide.
