Every software developer should know this story, it is a humbling and important lesson. Yes luckily most of can’t ship code that accidentally kills people but we can absolutely empathize with the conditions which led to it happening.
Thank you so much for the link to the postmortem. I will be sharing it and discussing it with my colleagues. We are currently working on the embedded software for an AED.
I recommend reading the entire postmortem, http://sunnyday.mit.edu/papers/therac.pdf yes it is quite long but if you write code in any capacity it’s worth the read
