My fallibility doesn't make stupid actions any less stupid. I've done stupid things myself, like ssh into prod to apply a "simple, one-liner hotfix" which ended up upgrading a minor annoyance into a partial outage.
I don't think there's a lot of value in labeling things as "stupid" unless they are somehow willfully or recklessly so, which is rarely the case. I really don't know what it gets you.
Nothing has ever gone wrong in production in ways that were fine on dev?
You've never written code to improve one metric, only to discover in prod it made another metric worse that nobody had considered?
How about a little humility for the ways in which we're all fallible and usually just trying to do our best?
