The US Navy operates a bit differently from commercial power; they have the freedom to not give a crap about being cost-effective. When it's time to refuel a nuclear submarine, they cut the entire reactor core out of the side of it and drop a new one in. The old core goes away to be disposed, and the submarine goes back out to sea.

It's amazing the safety record you can have if you just throw away the whole thing and start over every time you need to refuel.

It's also useful in learning from the mistakes of others, and stilling our anxiety that bad things can happen to us, too.

It's related to the cognitive bias called the "just world theory." It's what makes people blame victims. Sometimes more appropriately than others, and our conscious is more "shocked" the "less culpable" the victim is. And why people get more upset about bad things happening to animals than most anything else. Even children because of the assumption the parents or the state is partly at fault for not protecting them.

When a child molester is beaten/killed/raped in prison, people don't get too upset. Well he did bad things. Had it coming. Still totally the fault of the guy who attacked him! But it's a Just World when bad things happen to bad people. Don't molest kids and you won't be thrown in prison and attacked. Sleep softly.

When someone associates with thugs, and the thugs turn on him and beat or kill him, well, don't hang out with thugs and it won't happen to you. Just World. Sleep softly.

When a man is walking through a dark alley at night carrying a bunch of cash and gets robbed, well, that was kind of dumb. Totally the fault of the robber! But yeah don't do that and you're less likely to get mugged. Don't leave valuables in plain sight in the car, either. Lesson learned. World's still kinda just. Be wary, but you can still sleep softly.

When a woman is raped after going out wearing a short skirt, maybe drinking, well that's totally the fault of the rapist. It's complete bullshit that a woman can't feel safe wearing what she wants and having a good time. But there's a still a lesson to learn to help you avoid the same fate. She did put herself in that situation, after all. Maybe don't party so much, bring friends, watch your drink. The world is not just, but maybe you can protect yourself.

When something happens to a kid, what the fuck man?! The kid has no agency, there's nothing he could have done to "deserve" that or could have avoided what happened to him! But...where were the parents? Where were the teachers? CPS? It is an unjust world where anyone would hurt a child. But maybe you can learn a lesson about protecting your kids in this unjust world...

But when something happens to a defenseless animal...my God. Go John Wick on their shit. There is no justification, there is nothing the puppy could do to deserve its treatment, there's no way it could defend itself, there's no one who "should" have been looking out for it. Sleep with one eye open because there are monsters in this shithole of an unjust world.

And I'm not saying any of this is good or correct! It's a cognitive bias! But it's natural and hard to overcome.

Gotta be a troll. But if not, go through the mechanics of the Monty Hall problem. Take, for example, three playing cards - a king and two deuces. You be Monty and have your friend try to get the king, and have him always switch. It should soon be apparent to you that he is effectively getting *both* of the the ones he didn't choose originally.

Of course if you become suddenly rich in your 20's there's a pretty good chance you won't handle it well. I know personally I wouldn't have. I'd have done all kinds of stupid, blown through most of it, lost all my real friends, etc.

On the other hand, I'd have liked to have found that out the hard way...

On OS X the reboot is for user convenience. If you use the command line software update tools, you can install them as you wish, and not reboot. Then you can restart services with launchctl or reload patched kexts and save yourself a reboot. Does this take a lot of extra time and testing? Sure - thus the reboot.

But this case is black and white, so cheerleading is appropriate.

How about instead of blanket statements we look at individual cases and cheer or scold based on merit?

This is all free speech. Some speech is bad (violent and obscene comments to a teenage girl) and some is good (her dad publicly shaming the perpetrators). Don't get all hand-wringy about dad's good speech, just because "oooo things could also be bad." This is the same inability to make obvious value judgments that gets us TSA agents taking away little old ladies' nail clippers because terrorists might do bad things, despite the fact grandma is clearly not a terrorist.
