I agree that people only really respond when something goes wrong badly enough that its impossible to ignore.
I disagree that something like this would be a good thing though. Whether it's a power outage, financial crisis, or something else people will die. If that's what happens and society ends up adjusting course after then that's what happens, but I can't call people dying a good thing.
> people will die.
I don't think that's a good thing. But if we DON'T do anything, then even more poeple are likely to suffer. So while people dying is not a good thing, a thousand people dying is better than a million people dying because we don't do anything.
Same thing about burning your hand. It's not a good thing to burn your hand, but burning your hand once when you're young probably saves you from a more serious accident later on.
It would be a lesser evil rather than good.
This sort of thing was going to happen, with or without AI (state sponsored hackers, the US or China taking down systems they control, or whatever).
The later it happens, the more we will be down the path that lets it happen, and the worse the consequences. We are getting gradually worse consequences: AWS outages taking down websites, GCP outages taking down banks, attacks on fridges disrupting good supplies...
Its better for us to change path when something happens that causes dozens of people die rather than wait until its millions.
