I mean, that was over 40y ago. Same thing for the Ariane 5 failure which is a staple of safety-critical classes (at least in Europe), it's not getting any younger.

If all the examples you can conjure are decades old*, is it any wonder that people don't really take it seriously? Software power the whole world, and yet the example of critical failure we constantly hear about is close to half a century old?

I think the more insidious thing is all the "minor" pains being inflicted by software bugs, that when summed up reach crazy level of harm. It's just diluted so less striking. But even then, it's hard to say if the alternative of not using software would have been better overall.

* maybe they've added Boeing 737 Max to the list now?
