@toffy Kind of a related thing is that it's always fascinating to me when people talk about how nobody can be trusted, because people are fundamentally selfish and if they were trusted then they would ruin it for everyone etc. etc.

And then I look at things like this, where as you say every important system in the world is relying on multiple practically unmonitored points of failure and would be trivial to fuck up if people really were untrustworthy... and yet they keep running without issues for decades at a time.

In a weird way, it's a source of optimism for me.
