This is a good point. My comment is really an emotional reaction to the (very common) denigration of software engineers, so don't take it too seriously. But I also think that good software engineers can scale the reliability of their software to fit the purpose. There is a ton of software in medical devices, and despite the well-publicized fatal bugs, 99.9% of medical software works without error. In fact, the automation of things like drug dispensing at pharmacies has decreased mistakes. I think if you deleted all the medical software in the world, deaths would increase.
